I would recommend cleaning the pistons before pushing them back. Otherwise dirt that is stuck to the outside will be pushed into the sealing which might increase the risk of getting a sticky/lazy piston which is even more hastle than cleaning the pistons in the first place.

came to the comments to write about this... Yes - clean your pistons, specifically if you have contaminated brake pads or rotors. One of the pistons can be lazy - check if there is no dirt/mud there. There is a tool to push back the pistons but a screwdriver will work too.
@NelsonSherry Жыл бұрын
This is NOT actually a closed system as there is room for air to move in behind the bladder and compensate for the oil filling in behind the pistons as the pads wear. Thus there is also the ability for the bladder to expand to allow a bit of fluid expansion as brakes heat up or when you push the pistons back into the caliper. You do not generally need to let oil out of your bleed port to push pistons back when replacing pads. And, as noted by others, it's also a good idea to clean the pistons before pushing them back in to reduce the amount of dirt pushed back inside the caliper further contaminating your brake fluid. But then, whatever. You two make great inspiring and empowering content that is greatly appreciated. Please, keep it up!

In case no one has mentioned it.. I have a cool machinist tip for measuring brake pads with your digital calipers: Measure the little step like Syd did, but while that measurement is still on the caliper display, hit the “zero” key to zero the display. Then measure across the whole brake pad thickness, but now the display will read only the consumable part of the pad without needing to do any math. Neat huh? When you’re done reset the calipers to their normal state.. usually by holding the “zero” key in for 2 or 3 seconds till it reads normally (depending on your caliper model.)

There's no need to open the master cylinder bleed port *if* the system was never overfilled. But if you've previously done a lever bleed without resetting the pistons and installing a bleed block, you probably overfilled it and it will be necessary to allow the surplus fluid to come out as you've depicted.

Hi Syd, first off, I love your show and thank you for posting these really informative videos. Speaking of which, I have a question; I have a Road bike with a 1 x setup. 44 at the front and 12-28 at the back. I've noticed that, occasionally, Whenever I'm off the saddle for a climb and very seldomly, when I switch my gears, I would hear this ping at the chain set. Is this normal or, if not, does it mean something is wrong with my setup? will it eventually snap my chain or chip my gears? should I worry about it? Hope to hear from you soon and best of luck on your future posts! :)
@boldizsarmelegh8702 жыл бұрын
Hey. A ping could mean a lot of things, but if it occurs when you're putting lots of force on the pedals and shifting then its normal. However, this should generally be something to avoid. If you're shifting try to lower the force on the pedals, as it puts less strain on all of the parts. Just practice this. If you're worried about it you can always take it to a local bike shop and ask them to check it out in person

@jacksnyder93992 жыл бұрын
Hi man, While I don’t have any experience with SRAM road brakes, I have had similar issues with my G2 and Code MTB brakes. A lot of times on my brakes it’s just the lever reach and contact adjusters being out of place, I don’t know if road levers have these but if they do, definitely the first step. If lever adjustments fail, pushing the pads apart with the little plastic pad spacer/wedge widget sometimes works. Lastly, resetting the pistons by doing a lever bleed like Syd did will surely give you the range of motion back. You will be using a syringe an DOT fluid for the bleed though! Check out the excellent resources on the SRAM website for more info and bleed procedures. Best of luck dude!

Close, but filled w/ missed steps and bad "Bedding" advise. Is this a Brake Pad change tutorial or Brake Bleed tutorial ? Symptoms requiring a pad change are quite different than those requiring a Hyd Bleed of the system. Dedicating a vid to either a Pad change or Bleed operation would have given better detail for each of these maint tasks. At 5:35 you've mention that Resin and Metal Pads are different and that doing a "Bedding In" of the new pads isn't necessary if you've not changed Pad Types. Thats REALLY bad information and could be dangerous to an unsuspecting Noob doing a pad change for the first time. You should ALWAYS do a "Bedding In" of new Brake Pads regardless of weather you've changed types or not. Bedding a Pad into a Rotor simply matches the pad to the worn surface of the Rotors and removes any glaze from New Pads regardless of Pad Type. All Braking does is convert Kinetic Energy into Heat, it's why different Pad compounds have a different Stopping quality to them. Resin Pads are a mix of Heat resistant Resins and softer metal types and give a more "progressive" feel to braking but tend to fade with extensive use. They Wear faster but your Rotors last longer than w/ the Metal or Ceramic compounded pad types. The Harder Metal/Ceramic pads are Also a compounded mix that use harder metals than in Resin compounds. The harder pads "grab" a bit more firmly, don't "fade" as badly as Resin and will cause your Rotors to wear faster. If you're going to take the time to "mic" your Pads you should at Least know the Wear Limits of the Rotor type your using (found at the manufacturers website). My Tektro Rotors are New @ 1.8mm thick and are at their Wear Limit (the thinnest limit the manufacturer will warrant) at 1.6mm's thick. Most Rotor manufacturers go with 2mm or thicker when new. At 16K miles I'm on my third set of Rotors for my very heavy Fat Tire E-bike. Bedding In Any new set of Pad's is Always required, as I mentioned earlier, and if not done correctly could Easily ruin a set of rotors and/or be dangerous to the rider who's expecting their new pads to perform out of the box, because they Won't. I highly recommend taking a look at the Park Tool YT video on the subject. You'll learn some Very useful tips in a short period of time. Abnormal Pad wear (uneven wear) is usually a symptom of improper Caliper attachment/alignment, stuck pistons within the Caliper or a Rotor that's not running true. ALWAYS give the Calipers a quick cleaning between Pad Changes. Accumulated Brake Dust WILL eventually result in Caliper Piston movement problems leading to uneven pad wear. A simple blast of DRY air works Gr8 for this (like a can of keyboard cleaner). If you don't have access to compressed air, use Q-tips dabbed in Isopropal alcohol, it'll take a bit longer than a shot of air but will leave your Calipers clean and dry. You shouldn't ever handle Brake Pads or Rotors w/ your fingers. The oils in your skin will be absorbed by the very porous pad material and will cause noise or poor breaking. Caliper mounting Screws are Often slightly different lengths, do not mix them up or you risk damaging your threaded mount posts on the Front Forks. These same attachment screws (usually "Cap" screws, or "Allen" heads) will almost always have a stack-up of "self aligning" conical washers under the head of the screw. You can see them clearly in this video. Mixing up these washers will cause alignment problems. Again, make sure they go in the same way they came when new. Also clean the Rotors w/ a good wipe of Isopropyl Alcohol on a paper towel, it will remove any oils and make the Bedding In process go much better. You guys would benefit from being a tad more thorough w/ your Why and How explanations.
