Thanks!!!! I have a 1990 4x4 and have been battling this for years. Even went as far as taking off all the abs equipment, running old school hard lines directly to new master cylinder and using a manual proportioning valve. Better but still....with a horse trailer...stand on it and pray the electric brakes on the trailer will stop both. Bled them to death. Even gave up and took to dealer whose only comment was..."stops better than mine." (mechanic has same year truck). You should maybe change the heading on this to read 88 to 98 c/k 1500. Ran into this by accident. May help many more people. Thanks again!!!!

I don’t feel like adding this to a playlist, so I’m gonna like and subscribe to find it later when I decide to do this with my truck. Thank you for your service brother 🇺🇸

Thank you for sharing. I got mine from Oreillys, its a MC for. 2004 Escalade. Replaced the abs with a used one. Brakes work great now!

Excellent video and upgrade. Cant wait to this to my 95 Tahoe. Thank for your service🇺🇲

Something to know. I was thinking about putting the later MC on my 95 and had my ABS light on. I rebuilt my front end and while doing it decided to put new timken wheel bearings on. My bearings didn't feel loose at all but while in there you know. Well, to my surprise, not only did my ABS light go out but my brakes improved big time. I don't think it was due to the the ABS but rather that my wheel bearings were worn and underload defecting and basically knocking my brake pads back so they had to travel farther to engage. It's been well over a year now and a lot of miles and mine are still good. Just a thought. I fixed mine without trying. Thanks for all you do defending the great USA. FYI, I live in GA too.

Good job, I have a 94' Yukon, thinking of either this or the front disc brake kit. Love these body styles

I have a 99' K1500 Suburban and the brakes never felt firm enough for my liking. The ABS is actually scary when it comes to a full stop so I pulled the fuse and disabled it. Later this year I plan to replace the master cylinder & ABS unit and convert the rear brakes to disc brakes. If anyone has rusty brake lines like mine had I suggest buying the stainless steel brake line kit from Dorman. I bought mine thru RockAuto for $100 and some change and all of the pre-bent pieces fit perfectly.

Excellent Video, just wanted to add if this was not said in earlier comments. I would suggest bench bleeding the master cylinder. The reason for this is, if the master cylinder is not mounted level on the brake booster or this procedure of bleeding on the vehicle is done on an incline you can have a pocket of air that you will not be able to get out of the master cylinder. Hope this makes sense.

Did it today on my son's 1995 Chevy Suburban and it works awesome!!!! Didn't even bleed the breaks

Thanks for the video, I've been wanting to upgrade my 97. I feel more confident about doing it myself now!

Awesome video! Need to do this on my 98 tahoe in the worst way (same situation, peddle almost to floor)

Thank you. Good job. Good video. Great explaining. You have motivated me to do this on my ‘95. Buy the way, nice truck you’ve got there. Clean.

Nice truck. Definitely a keeper. I did this upgrade on my 98 Z71 and after several new boosters that couldn't develop enough pressure I got a complete hydroboost system from a pull it yourself yard. Hydro, master, 3 hoses and dual return PS pump for 125 bucks off a 99 suburban 2500. Monster brakes with very little pedal effort. Will never go back to vacuum assist. You have to get the master cylinder, mating diameters are different. Miss the newer reservoir. Fits stock brake lines.

Love the lights in the bumper.

Great video man I feel like I got every bit of information needed to feel confident enough to do it myself this weekend. My pedal goes all the way to the floor, from one day after another it just went out. I was braking really hard on first day of school from dropping off my brother at practice n I was pissed off wit all the traffic. So yeah I’m pretty sure I broke mines lol.

I JUST FINISHED IT WORKS GREAT. THANKS

Thank you for the step by step on this upgrade, i`ll be buying the parts needed for my 1998 1500 swb. I hate that spongy brake pedal feeling.

You will need to blead the anti lock System you can find video of the process on KZfaq and then blead the breaks starting with the far wheel first just watch the mc fluid level. Nice upgrade. Or find someone who has a snap on tech two to cycle the anti lock system. To blead air and then you will go through the windshield.

Super clean truck, man!

Just finished installing new master cyclinder,wish I would've seen your video first.I would've upgraded to the newer style. Thanks for the info anyway.

Great video. 💯👍🏼😊

Outstanding!

Nice video, thanks!

We need more pickup videos!!

I have a 96 with 306, thousand breaks are crap but I can't complain about much else 4l80e went to 260,00 Not complaining. Never knew of this Upgrade

Nice rig

I have a ‘96 1/2 ton, and a ‘99 - the ‘99 is the new style truck and has a cylinder like the one you put in, the ‘96 has the same as what you had at the start. I didn’t realize they are swappable, the new style reservoir is easier to connect pressure bleeder to

I did it n it work

I have a 1995 Z-71 and as long as the rear brake shoes are adjusted properly and the ABS pump is working correctly you'll never have a spongy brake pedal. A little preventative maintenance goes a long way.

Thanks for the video. I’ll be changing mine out this weekend

After your upgrade with your brake master cylinder I see your ABS light is on while you're out testing your brakes and mine is onto now I just seen in another video about that ABS system it's a hydraulic system you got for brake lines going into your ABS system I'm wondering if they don't need to be glad or if they're not even working I'm going to try to played mine and see if that makes my brakes any better good job on the upgrade to I think I'm going to do that myself

Gonna do this tomorrow!

Got a 96 GMC Yukon I'm having the same issue with gunna have to try this. First I have heard of it, and I have head four Silverados Z71's Heavy Halfs all of them 4X4. Thanks for the idea.

I have a '99 Suburban with spongy brakes. Replaced front and back brakes. Still spongy after bleeding it. What year brake master cylinder do you recommend I replace it with?

I did my Truck And is Way better .Thanks

Mine is the same way a lot of movement before the brakes engage been looking for a solution. Ty

I have a 97 and when the heads cracked I had the dealership put a GM performance 383 in it since it was a direct fit.

Appreciate it.

Your truck looks almost identical to mine. Mine is a southern comfort though. Z71

I noticed some videos use the NM4073 and others use NM4074! Any difference that you know of?

That master cylinder costed $106.00 from Auto Zone, haven't installed it yet, will give you a update...

Quick question- I recently did this mod to my 1994 K5 Blazer and the ABS light is stuck on after I bled the all the brake lines. Any suggestion why that might be?

i have been selling the master cylinder 1 a week thank you

Wonder if I can put a knew brake master on my 99 Tahoe. What is best knew year to put 🤔07

Soooo. Would this work on a 89' suburban?

any difference in disk/drum brake wear?

Can we get an update on how your brakes are doing now with this upgrade??

i am in Australia and have a pretty well used 92 gmc c1500 5.7 2x4 auto. can this cylinder be used with a non ABS brake 1992 GMC 2x4 5.7

o7 I have a 1998 gmc c1500 3rd door v8 ,pick it up new in 1998 and this have it. i also have low miles for my duties in the military.

Dang, I have the same Wheels on my 95 white extended cab..lol

We're did u get the line adapter

Did anyone run into the problem of the flair on the current line is larger than the flair inside the BLF-26C adapter and won't seal?

As of 12/4/22 that same master cylinder is $117.99

Wow... You said $60.00 for the NM4074? I need to move to Ga. I paid $115.00 & it help my pedal a minimum of maybe 5-10% only... Nothing crazy like some of the other videos say. I bled, bled, & more bled... My pedal barely feel any different. My calipers and wheel cylinders are all original 23 years old never had a problem with them... Brake hoses was changed... I really don't see the hype in doing the swap NBS to OBS...

Will this exact setup you have work on my 1996 C1500 2wd??? I hate the way my brake pedal feels I've replaced everything down to all brake lines and still hate my pedal feel... Its terrifying how far the pedal goes lol

Will this set up work on a 1997 silverado 1500 2WD?

Will this work on 89 k1500 scottsdale

My brake pedal feels just like you described before you upgraded the brake master cylinder. I have a 1996 Chevy 7.4L 3500 dually so do you know if the part # would be the same? Did you use any thread loc on the adapter or original fittings? Also I notice your battery guage is to the right side of 14. Mine is always to the left of center with a new altenator. Your engine sounds great! Thanks! Subscribed!

I recently came across your video and tried the same upgrade on my 99 chevy tahoe. Question I have did your break pedal stay at around 3/4 of the way down like you mentioned in the video? Did it improve when you bleed each caliper and drum? I did feel a difference in break pedal but mine also goes about 3/4 of the way down before it holds there. I also bleed each line. Thanks for the video

My 1996 GMC K2500, Suburban, 7.4Liter, 8600 GVW has the same problem. Mine has hydro boost. Does anyone know if I order a 2000 model year of my same truck with Hydroboost if I will get the improved MC? Also, since it has been a while now, Touge Guy, were you able to get a better bleed on the whole system and improve it more or has it remained as it was in this video? Thanks for showing all this!

You must have removed the clear coat off of your rims?

@ Tough Guy. I'm having that same issue and have replaced everything but the steel lines, even bout a good used abs pump and module and still have the brake issue. I got a 98 k1500 with 5.7, do I just order a 99 k1500 master cylinder then

Will this swap also work on 1990 c1500?

Hey my man I bought the same part number from autozone but mine has a skinny piece of plastic sticking out the back are there more than one??

Thanks, great video. Some questions... I have 98 GMC Sierra SLE Z71 115K original miles and want to increase HP keeping cost low. What upgrades do you recommend?

Do you have the brake master cylinder link so I could get one for my 91 Chevy 2500 truck

I just needed to change my master cylinder because my brakes were getting spongy Now the brakes work like a new Z71 GMC

Nice truck..let me know if you ever decide to sell it!

I forgot to Ask you ,My Truck is a 97 4X4 k1500 just like yours , The MC would fit on My Truck? Let Me know Thanks

Good video, what exhaust setup are you running? Sounds really good

Wish I saw this earlier

What's the model number for the adapter part

So the new master cylinder is for what year and model of Chevy?

hand tighten the lines before you bolt it up. makes it much easier just saying

how much of a raise on your hood? 2" or 4"? thanks.

So let me confirm this, all you have done is fitted a master cylinder for 99 plus on your 98. Is that correct?

Great video! Just curious what mufflers are you running? Sounds Great!

Are those chrome American Racing wheels you have on your truck?

Would this work on a 93? And what year would i use?

Why is your ABS light on?

Where did you buy it

Did you also bleed the anti lock unit to get your abs light off. The abs controller has a bleed valve on it that needs to be done also after a master cylinder replacement.

Would it work for my 2wd

do you know if it would be the same parts for a 98 c1500 4.3? stock parts look the same

It’s been a year, how is the brakes now?

My daughter and I have a 97 and a 98. The brakes suck. I’m thinking about trying this. You could tell a big difference? Worth changing it out?

I too install the mc then bleed it vs trying to shove a screwdriver in the bore while it's clamped in a vice. I don't get paid enough to work that hard. Just put a NBS mc in a 1994 suburban. So much nicer now.

tkx do I need two duel master cylinder adapters #BLF-26C-

You are a God amongst men.

Since posting this video, how are your break now?

What muffler are you running. Sounds good!!!

This actually made the truck stop better?

Anyone have problems with the adapter not fitting with the brake line? It fits great into the master cylinder but brake line is loose and leaking fluid.

Instructions were unclear, my blinker fluid overflowed and I have more horsepower now?

same year C/K3500 (non hydro boost) master cylinder has the same effect without that monstrous reservoir, but I think you need two adapters instead of just one iirc

Touge guy will this work on my 97 2 door tahoe? brakes suck

This truck bodies here are hard to come by these days especially when they're in good shape and they want crazy money

my 92 has great brakes not soft at all

Am running 3/4 ton master cylinder

Why the booster super rusted
