I have scoured the net with various keywords and nobody has actually stated what the purpose of the rubber sleeve is on the bottom of a caliper pin. I'm not sure all disc brakes have it, but some do and in some cases the rubber-sleeved pin goes at the top. If it helps lubricate, why doesn't the bottom one have it? I've also run upon people with seized pins and it's because the rubber can toughen up or expand and lock in place. Wouldn't it disproportionately stiffen one pin vs the other leading to uneven braking?
#bundysgarage # calipepin #discbrakes
Finally, mine are a bit screwed, so I plan on making new rubber sleeves with some tubing from lowes (I'll dremel wheel the matching grooves in place). Any potential problem with that, assuming I can find the right fit?
The little rubber thing maybe 5 mm thick that goes in a grove at the end of the caliper pin. A couple months ago I refurbed my front brakes and had the same question. The two packs of new pins I bought had the slots for the rubber thing on one pack, but the other had no slot. I ended up not putting any of the rubber things on. It seemed like most of the reason my calipers were seizing up was that rubber thing breaking up and getting stuck in the sliding area. So far I haven't noticed a problem.
It may have to do with squealing but I know these cause problems for some people as they can get very tight and greatly limit movement of the pin. Using a rubber-destructive grease will certainly come into play here.
On toyota/scion vehicles, there are rubber o-ring bushings on some of the sliding pins for the calipers. On the front, only the bottom one I believe has it... On the rear, both do if I remember correctly.
When I did my brakes a few months ago I had big problems with the pins seizing up in the rear. Once I got them un-stuck, cleaned, relubed, replaced the pins and bushings, etc... I noticed there was much more resistance with the bushings on (I am sure by design)... Because the calipers were all seized up, there is more resistance than normal I believe.
Either way, they did slide properly after the fact but not as easily as the front ones. I removed the bushings and tested the operation without and they worked extremely well with little to no resistance at all.
But I figured that bushing had to be there for a reason so I made sure to keep them in and just lubed up as much as I could with sil-glyde (the permatex purple stuff seized them shortly after the first time... Don't use that stuff with any rubber).
My question is, are those bushings absolutely necessary? I plan to check/lube the brakes before winter again and want to hear some opinions on these... If they help the rear brakes function better (less resistance with the pins) should I remove them? When doing my dad's Prius brakes, I noticed his rear brakes had the slot for the bushings, but with no bushings present (nobody ever serviced them before me). So I am guessing it won't cause any damage if Toyota practice this on their other vehicles.
Just looking for some thoughts though... What is the function of these bushings anyway? Noise?

Same here. I own 2017 Toyota RAV4 se and I started hearing some noise like break pads were worn as I was driving. i checked the pads and they were fine. Then I did a little research and took the caliper off to check the pins and sure enough the ones with the rubber ring were completely stuck on the front and rear calipers. Breaks have never been replaced as the car only has 40,000 miles still on the original ones. I threw away the bushings, cleaned the pins well and greased them up with Toyota grease and now not only that I don’t have a vibration when breaking but I also feel like the car has slightly more power!

I had a rattle after taking my car to the local Honda dealership. They measured my brake pads to see how much life was left in them. Apparently the left rear was dragging and was down to 20% while the rest were at 80%. I wasn't happy with the rattle and a few other items that turned up broken or missing, so I haven't been back. Fast forward a year or so, rattle is still there. Replaced those rear brakes long ago, but the rattle in the front was still there. Over the past weekend, I replaced the front brakes (rotors still good). What I discovered was that the lower bolt which holds the caliper to the carriage pin was missing. Thus, my brake pads were indeed rattling against my rotor the caliper was not correctly aligned with the pad, and the metal backing of the brake pads had removed themselves from the pads (thus creating the occasional grinding noise I heard). My theory is that the dealer measured the pad thickness, and then forgot to replace the bolt when rotating the caliper back into position. This is why you do the simple work yourself!

@glasser2819 4 жыл бұрын

grease is what is known to chew up the rubber plus time and heat. The only lubricant to use on the brake slide pins is SILICONE based ie. not Petroleum based grease ! The "brakes grease" is a mixed formulation that dries into a gum with heat to quiet the caliper to pad noise. Most of its petroleum lubricant promptly evaporates to render as gum. It should be called "brakes GUM" keep it away from your slide pins because it is oil based and short lived unlike high-temp silicone. 👍🏻

DO NOT USE ANY CLEANERS ON THE RUBBER CALIPER GUIDE PIN BUSHINGS OR BOOTS as was suggested in this video. Simply wipe them off with a clean & dust-free towel or cloth. Using cleaners on them, especially gasoline, brake parts cleaner, acetone, etc. is the quickest way to cause uneven brake wear. Most cleaners will cause the bushings to swell causing the guide pins to stick inside the bracket. Also, DO NOT SPRAY CLEANERS IN THE PIN'S BRACKET HOLES. if you spray cleaners inside of these bracket holes, the bushings may continue to swell over time, seizing them entirely. DO NOT REMOVE AND DISCARD THEM EITHER, as was also suggested in this video. THEY ARE THERE FOR A REASON. The guide pins with bushings are always on the "trailing" end of the caliper and provide a slight amount of additional resistance compared to the "lead" pin, which is simply a slide and pivot. The additional resistance added by the bushings provide stability and helps reduce brake noise when braking heavily and when the brakes are released after moderate to heavy braking. This shadetree should seriously consider studying up before working on anyone else's brakes or offering bad advise to others. Reference: ASE Certs and 28 years of professional brake repair experience.

you want to take those chrome inserts off and clean any rust from the steel of the caliper bracket and then put grease on that before you put the chrome inserts back in so that you prevent "rust jacking" of those chrome inserts. "rust jacking" will restrict movement of the brake pads and the grease applied under the chrome inserts will hold "rust jacking" to a minimum.

Many of the Japanese caliper manufacturers use this differential pin arrangement. The plain pin is called the Guide Pin. The one with the rubber bush is called the Lock Pin and and is usually positioned at the trailing (second pin for a point of the disc to pass) end of the carrier. Carlson makes a kit that has the rubber bellows & the bushings.

@MrBikedrummer Жыл бұрын

Thanks for your explanation. I believe many people don't understand this and the trailing pin changes from side to side. Rotor spins counterclockwise on the left side (driver's side), so the trailing pin is on the bottom or front of the caliper. Opposite for passenger side. Great tip!

Thanks for the discussion and I'm not sure that it matters.

I consider the boots/pin rubber bellows items as part of a complete brake job so I always have the rebuild kits on hand when I dig in... yes they can swell and also the boots can get weak and tear or lose ability to keep water out so I generally will just order all the parts even if I'm just changing pads. If they are swollen generally they haven't been serviced (or correctly) in a long time or the boots bad---Using silicone based lube (lightly) and replacing rubber to me is easy enough...but agree it's not mission critical but If I have it torn down you can count on just replacing them before. you get to that point.

Just done a brake upgrade on my Fiesta ST to the Mondeo ST 220 calipers. Im in the UK so guessing that would be the Ford Fusion in the US but Im not sure you got that model. The calipers we’re used so cleaned, painted and rebuilt. Both are now sticking on all the time and I’m thinking this is the cause. Only difference I’ve got is that the rubber sleeve is around 15mm long so without it there’s quite a bit of play in the pin. I tried it before fitting them and decided they must be there for a reason so put them on. The one without the sleeve went in perfectly but the one with had to be forced in. I can’t just buy 4 kits like someone suggested as the bores are a slight different diameter meaning if I use the ones without a sleeve in the bore meant for a pin with a sleeve there’s even more play. Going to strip them down and remove the sleeve and see how I get on. Wish I hadn’t doubted myself now 😂Thanks for the video 👍

One of my caliper guide pins is not seated properly in length, it wouldn't bounce back to the same height as the other guide pin even after proper lubrication. I also replaced both rubber boots (not the tube thing on the slider pins as mine don't have one), and tried sliding each guide pin into each bracket hole trying to see if it was the cause of the pins, and the good one would still work fine and the bad one would still be problematic no matter which pin it was. I did some research and found that there is a limited number of posts talking about this issue, but apparently they were saying that the reason behind this was due to too much vacuum inside and would need to let some air in? I did test out taking the bracket off and cleaned out all the old grease inside the bracket hole of the problematic one, and put the guide pin in to see what would happen; it turned out that it would not move at all without any lubrication. After lubricating the pin BUT without installing the rubber boot, the pin would indeed tend to bounce normally just like the other good one. But after installing the rubber boot (even a new one), the issue would reoccur). There are no proper guidelines showing how to solve this issue. Do you have any suggestions?

I can’t tell you how many sets of brakes I’ve ruined before I figured out it was that grease. I also have removed that rubber bushing because of swelling. I would only recommend that you clean out all of the old grease in the bracket bores because it may react to the new grease, and possibly gum the pins up. It can be time consuming but it’s better if you clean out all the old grease whenever replacing with a different type/brand.

The reason for those rubber "spacers" is important! It keeps the slider pin in place, centered, and keeps the pins from scraping against the caliper. If it came with your vehicle, "put it back in"! An engineer designed it for the vehicles company and decided it works better with it. Remember, it's there for a reason. When you clean, restore and/or regrease your brake caliper and it doesn't let the slider pin go back in, it means the rubber boot/bushing/spacer is stretched and/or swollen, and needs to be replaced. It costs anywhere from $3.50 to $5.50 as a kit with new rubber boots included for both of your front or rear calipers. Do yourself a favor, and just reinstall. Oh, and as BundysGarage said, clean out "all" of the old grease and use the proper lubricant. I use Sil-Glyde or PermaTex (24110). Apply some on the boots, pins, and the shims of your brake pads. You'll be glad you did. GL!

Thanks for your comment. But I never put grease on the back of brake pads. It didn’t come from factory that way so why do it? I’ve had this discussion with lots of mechanics and some say do it and others say don’t. I’m in the boat 🚣‍♀️ that’s say don’t do it. As far as the runner bushing being left off, it’s not that big of a deal if it’s left off. The reason I left it off is, if the wrong grease it used on the seal it will swell and prevent movement of the caliper. Causing the brake pad to wear unevenly. So you tell me this, do you want to keep it on there cause some engineer put it there or do you want to save money by not having to do the job twice???????

I had the outer pads on the rear on my Mazda 6 worn to the metal. I just threw on two new rotors and akebono pads. When I removed the pins they were almost dry. I left the rubber piece on and used permatex synthetic ultra brake lubricant. Both pins slide freely. Let’s see how it performs long term.

You do not even have to use the wrong kind of grease. I recently bought completely new rotors, new pads and new slide pins with new rubber boots. It was my first brake job with one of the slide pins having this rubber sleeve. Have done quite a few brake jobs. The calipers were working fine so I did not have to rebuild them. The slide pin without the sleeve was easy to install, but the slide pin with the sleeve was quite hard to get into the bore. It seemed like the edge of the sleeve got caught in the bore and it eventually tore off. I installed the pin anyway but my gut feeling was not good. That slide pin did not slide like I am used to. But I thought it had to be there. Well, now the brakes on that wheel drags and the wheel gets hot and I have a loss of power. I Have to redo that part of the job and judt throw that little sleeve into the abyss. Over engineering. It might work well on paper and right out of the factory and fence off some customers complaints, but not on a used car out of warranty, at which point the car company gives a rats ass if it gets stuck. Rather have some rattling or minor vibration than a hot wheel and loss of power.

At least you have real world experience and know what’s up! Your not going to notice any change with that rubber piece gone when you brake. I have cut them off thousands of cars and not once has someone come back and said, my brakes are making a small noise. Won’t happen.

Obviously it requires very high precision to have both guide pins moving smoothly in their respective hole. The pin-to-hole precision would be easily achieved if there were only one guide pin. But as we have two guide pins operating in high temperaturen we can’t have the tight fit on both pins at the same time. So in my mind it is obvious that the pin without rubber has a very high pin-to-hole precision and the other pin with rubber must have less precision for it to fit into it’s hole. This lack of precision is compensated by the rubber which also prevent noise/rattle. So in other words: one pin is for high precision fit, the other pin with rubber is to absorb the tolerance when fitting two pins in cohesion. Placing the rubber pin in top or bottom position does not make any difference, it will have it’s tolerance absorption function anyway as the drill holes has the same dimension

This is why Honda doesn't use those rubber seals, switching to flattened metal surfaces on one pin, but it doesn't mean those seals or flattened pins are useless. The purpose is the leading edge of wheel turn creates a 'chatter' inside the pin housing and can squeak or wear pads unevenly. If it's your car and you don't notice, that's fine. But if it's a customer's car, do the right thing because it's their vehicle investment and they trust you not to cut corners with their car just because you decided something designed for the vehicle was bllsht and you're not doing it. Another example on Hondas and Asian vehicles is throwing out the tiny screws in the rotor just because they're difficult to remove and supposedly, 'don't do anything'. Fact is, they aren't there to 'hold the rotor' on during a brake job. They're there to stop the tiny rotational chatter around the lug posts and when you throw them out, it translates into chittering of the wheel at high speeds, 70 mph and up. Next time you take off the wheel, look at the space around the lug posts and you'll see what I mean. Most American manufacturers don't care, but it's one of the details Asian engineers addressed.

@Yophillips3272 2 жыл бұрын

I think if the rubber on the pins cause the brakes to seize up eventually it's a bad design. What would you rather have possible noise or a locked up brake cooking your wheel bearings, putting strain on your drivetrain etc.? The screw on the rotor I take it you don't live in the rust belt, the lugnuts center the rotor that screw isn't doing anything.

I have the same "problem". but one of the comments here indicates the purpose is push the brakes away from the rotor after the brake is released. This makes sense.
