Spongy ABS Brake Fix 88 to 98 Chevrolet Silverado

Here is how to fix spongy brake pedal feel on a 1988 to 1998 Chevrolet Silverado truck. If your truck has an antilock brake module in it, and that ABS module has air bubbles in it, you will have spongy squishy brake pedal feel even if your ABS system isn’t working. In my case, the brakes were so bad that the brake warning light came on. So in addition to bleeding the brakes at all of the wheels, you also have to bleed the bubbles out of the ABS module. If you have a module like the Kelsey-Hayes one on my truck in the video, you can use the bleeder valve on it to bleed the bubbles out, and then you need to bleed the brakes on all the wheel cylinders starting with the one farthest away from the master cylinder, and working your way to the one closest to the master cylinder. If you do this, it will fix the spongy squishy feel that you have in your brake pedal on your Chevrolet Silverado truck. In this video you see me getting the air out of a GM ABS module.
Here's where you can get a brake bleeding kit:

My mechanic installed two new master cylinders, trying to fix my mushy brakes, after a full $1,300.00 brake job, and in the end told "that's just how GMC trucks are, which really pissed me off as I knew the truck had a very firm pedal before the brake job.

[@texaswildcat2000]

Many shops today don't fully understand the older abs systems since newer, for probably the past 15 years, vehicles don't require such brake bleeding as this, just bleed the brakes at the wheels and that's it, many using a pressurized bleeding system at the master cylinder....

@@corriganworley4961 Pretty much you need a Tech 2 scanner to activate the ABS and get the air out unless you can drive down a dirt/gravel road and slam on the brakes enough to get the ABS to activate.

As an update... To anyone not getting any fluid out, depress the button even harder. It starts out flush in its own little orifice, but you need to put enough pressure so the button actually pushes in like a mm or so After I realized that, I got fluid flowing

I had to really dig around on the Internet to find a solution and make a video about it. I took my truck to a couple of different people who have been mechanics when these trucks were new, but nobody knew how to fix it. I’m glad I could make this video to help people figure it out. Most people who have a truck this old can’t afford to pay a lot of money to fix it or replace the whole brake system.

Secondary bleeder is under the blue pigtail wiring where all the brake lines join in the abs. Use a mirror to see it. You will have to unclip or snip the plastic clip that holds the wire going down to the frame rail. Then ziptie it back into place.

I have a 1998 GMC 3500 4X4, with the same problem bleeding the brakes, spongy pedal. After using a Motive pressure bleeder 2x over 3.5 quarts each time. 0 air bubbles and clean as a whistle. Thought after seeing this video that all my brake bleeding problems were over. Sorry! WRONG!!! There are 4 ports in total, on that system to bleed. As far as I'm aware GMC/Chevy would have the same ABS. But I could be wrong! If you look on the opposite side of the ABS unit, there's another bleed port just like the one your looking at on drivers side in video. It should have a rubber cap on it. And there's 2 more at the base of the ABS facing the firewall. Pain to get to and if you don't look real hard...you won't see them. I bleed them all and it looks like my ABS module is hooped. Now trying to find a local ABS module rebuilder. Good luck to everyone with their brake issues.

[@CarsnStuff]

oddly i just tried this and nothing came out at all. i could see the little plunger thing actuating while the peddle was being depressed and pushed it in but nothing came out. no hissing or any fluid of any kind. The truck has some spongy brakes and i've bled it a few times just put new pads and shoes on it aswell.

[@ArtDaBarber619]

Were you able to get the fliud to drain? I am having the same problem.

[@garydoyle7155]

to be clear - - pop the rubber cap off and you'll see that pin he's holding in the video push out when the brake pedal is depressed - - what you are doing is holding the pin in then having the pedal depressed , release the pin and have them release the brake - - push the pin in and then have them depress the brake pedal until you get a squirt not just a trickle come out around the pin. Be sure to bleed the lines after because the sensor that puts up the red light for brakes on your dash is in or on the module - - you can clear the warning light but still have air in the lines . Good video - - many people don't know about the module bleed

[@DirtRoadie]

Although this seems clever enough, I'm not sure I fully accept it. Especially considering that many commenters describe their lack of success. But also, on the particular ABS module being shown there are two of those little capped bleed valves, not just one. The bleed valve shown is for the front brake circuit. The other one (rear) is on the same axis on the other side of the ABS module, is much more awkward to get at, and is angled slightly downward - not really conducive to removing air. So it seems that this has, at best, a 50% chance of accomplishing anything.

[@CamConscious]

What if you disconnect the ABS altogether?

[@hondafreak8613]

Theres a special gm tool to hold that proportion pin from coming out. Otc #7853. When it comes out, its blocking pressure to rear brakes That combination valve is there incase brake line leaks. That combination valve cuts pressure to rear brakes so the front brakes will still slow u down. You have air in the rear lines because the combination valve is doing its job.

Replaced master cylinder, bleed brakes, adjust rear drums, was about to replace abs mod when a 40 yr ASE mech said find dirt or gravel road, run up to about 30 mph and slam on brakes. Did it about 5 times and now have rock solid pedal. Said this activates the abs system and bleeds air from it. Hry, worked for me!

[@hoohoohoblin]

I’ve heard that that method works. In my case, the wheel sensors have gone bad, so the antilock brakes don’t engage when I hit the brakes. So I have to bleed them this way to get the air out of them. They will sensors were notorious for going bad, so this method is good for anybody who has their abs brake dashboard warning light on and wants to bleed the brakes.

[@TH3C001]

I remember seeing this video and trying the same method for little to no actual improvement so I'm not sure what's going on with my brakes. For a decade my brakes have been not only soft and spongy, they are slow. I can slam the brakes and the pedal will travel slowly as if the lines or hoses are clogged, the harder I press the slower the pedal travels. So if some little child ran out in front of me there'd be nothing I could do to stop in time. I have replaced brakes hose left right and rear, the master cylinder, the power booster, both front calipers, both rear wheel cylinders and over the course of a decade have bled several gallons of brake fluid through my truck. On top of trying to bleed that little valve thing I've also read it needs to be held down flush and in place to properly bleed the brakes (or maybe just to properly bleed the rear brakes) and still the brakes suck. I even became friends with a mobile mechanic who hung out at the store I work at and was able to use his scanner to run 3 automated brake bleeds, _still, no, improvement._ At this point I'm ready for my last resort, I'm gonna speak to a Chevrolet dealership shop, try to find an experienced or high ranking technician, and tell them my whole story and tell them I give up and that no matter what it takes or costs I want my brakes to be firm and responsive again, I want to be able to slam the brakes and break my nose on the steering wheel. I don't care if they need to stick my truck on a giant rotisserie to flip it upside down to get the air out of the lines, or stick it in some giant NASA vacuum chamber to suck all the air from the lines, whatever it takes to make the brakes work again.

[@MaineGirlOutdoors]

Does this fix the abs grinding that occurs when breaking normally? I just had a break job done and the mechanic (not my mechanic) said he didn't know how to fix this issue. Said he "went over the abs" and couldn't find an issue. It's so annoying.

96-00 gmt400, abs scan tool power bleed from OBD II

[@bojackson6714]

?

[@tinytim9453]

@@bojackson6714 Mechanics uses scan tool to command the abs module to bleed itself , and then mechanic bleeds at wheels. Voila, good as new!

[@geovannirios7565]

If I already bleeded the 4 tires do I have to do it again after bleeding the abs system?

[@hoohoohoblin]

Yes. There could still be bubbles in there.

[@Devo1987]

[@Anonymous-it5jw]

Dot 4 is not the recommended brake fluid for your truck, the additives could cause issues with your old brake system. Get a trusted professional mechanic to check it out.

[@bradmorgan9000]

That fixed it now its as good as new !!! Just changed the break booster

[@hoohoohoblin]

Excellent! Sorry you had to replace everything else before you figure that out, but now you have a totally new braking system.

[@johnnyperez8534]

I tried doing this on my 97 Tahoe and it wouldn't release any brake fluid. I'm wondering if my abs is messed up.

[@mwheatley63]

Mine did the same, nothing came out. Did you figure out anything?

[@johnnyperez8534]

@@mwheatley63 no sir I haven't figured it out yet. I'm more than likely gonna just replace the complete ABS pump and control module.

[@brianostrander8262]

Dang wished I would of seen this before I sold my gmc.

[@bradmorgan9000]

Just found out what the problem was ! Had been using non-matelic pads with out any problem. An change to ceramic. Thats when all my.problems started. The ceramic pads are a.little bit thicket causeing them drag. And create so much heat

[@hoohoohoblin]

Thanks for posting that. I wondered what the problem was, if you had replaced everything. It’s crazy that they would make replacement pads that are thicker than standard. I’m glad you got it figured out without doing too much damage to your truck. Sorry you had to buy so many parts.

[@shobud7561]

Great job " I've been dealing with this problem a while now with a spongy pedal . Thank you for this info ...

[@hoohoohoblin]

You’re welcome. I hope it helps.

[@supertruckertroy]

Thanks needed that info.

[@geoff0brn]

Tried a bunch of times.... no fluid came out : (

[@ArtDaBarber619]

Were you able to get the fliud to drain? I am having the same problem.

[@sheikhmohomad6438]

Cool worked for me too. I replaced the brake master cylinder did the whole bench bleed before I installed it. Then bleed the brakes and it was still spongy. I watched this video and then bleed that button without doing a re-bleed of the wheels and the brakes were a little tighter then I went out and slammed on my brakes to make the fluid run threw the proportioning valve and bam good as gold so this method does seem to work. At least it helped. Thanks!

[@hoohoohoblin]

You’re welcome.

[@thechoznjuan6886]

Consider that quarter a tip for the tip you just gave all us OBS owners. Thanks

[@hoohoohoblin]

You’re welcome. I’m glad I could help.

[@rudolph963]

Was looking for a new ABS for my 95 2 door which they don't make anymore. Used this tip and it worked! Now I have a brake pedal, just like new.

[@hoohoohoblin]

That’s great. I’m glad I could help. It took me a long time to find a fix for this, so I’m glad I could share it with everyone else.

[@rachaelbroach1297]

I have a 97 Chevy Silverado 1500 I have been having problems with my ABS locking up and stopping me like i am hitting a brick wall. Everyone has told me what is wrong of course So far i have replaced the brake booster and master cylinder was going to change breaks but pads roters and all is great dont need changed. the one Plus in this so Nothing has worked now they r telling me its the ABS MODULE okay enough is enough my truck has been sitting at mechanics for a week just got the part in (modulator) had to find one myself because they dont make them anymore for my truck apparently too old Well Whatever So my question is Could this possibly be the Module or do i just need to bleed the Module thats on there ????? I AM DESPERATE here !!!!! I haave already spent over $1000 TRYING TO FIX THIS So really getting frustrated. THE thing is this was my DADDY'S truck i lost him in Jan 2022 from lung cancer I will do whatever i have to to get this running right or its going to become my new lawn ornament Someone please help Desperate in Missouri Thanks all. I also really enjoyed this video at least you explain instead of just doing and have to figure out from looking and thumbing it

[@hoohoohoblin]

That’s a good question. The brakes on these trucks are terrible. Some people illuminate the ABS module entirely, so you can look around on the Chevy forums and see if you can find somebody who explains how to do that. I’ve never been able to find out how exactly that works, but I know it can be done.

[@DickWheels]

I have a 99 tahoe. I've replaced both front calipers and lines, all rear brakes, upgraded to NBS master cylinder and even used the scan tool to bleed. I've had an amazing hard pedal for about a week then it has now slowly gone back to having to push it half way before it works and mush. Same as it was before all the upgrades and old master. Cannot find a leak anywhere. This brake system is a disaster!

[@bludy22]

Thank You for the video. Short, sweet and to the point. Valuable information. Well worth the $ ;). Subscribed.

[@hoohoohoblin]

Thanks!

[@krowtis]

Great video. Thanks for posting it

[@hoohoohoblin]

You’re welcome. This was bothering me for a long time, so I’m glad I figured it out and was able to help other people with it.

[@MOE13576]

Didn't work.. no fluid came out.

[@elainerussell924]

Just use the anchor drop it threw the rotted floor 😆

[@arnieselectric007]

Great job brother, gonna try it on my 95 Z-71...Thx...Been frustrated for 2 days...

[@hoohoohoblin]

Thanks. I hope it works.

[@charliewilson3120]

Well I’m doing a 98 Tahoe line broke truck got parked for 6 months replaced lines from abs back to wheel and I can’t get any fluid air nothing out do you think this would work

[@hoohoohoblin]

I think so. It happened to me when I had a brake line spring a leak. This fixed it.

[@ksmons]

I have a 97 C1500, original owner. First few years, no issues but somewhere around 2000-2003ish it developed the mushy brake problem. I've been pulling trailers literally every week with this truck, boat and jetski year around... More than once I've tried bleeding them, replacing Booster, Master Cyl and wheel hub cylinders and still have mushy brakes. I've had a shop or 2 look at it and they can't figure it out. Now my brake light won't come on and I assume it's because I had to push 2-3 inches back just to engage the brakes and I know the sensor near the steering column is good because I replaced it. I will try that "Button" thing this weekend plus bleeding everything again and let you know. Thanks for posting this video...

[@hoohoohoblin]

You’re welcome. I hope it helps. People have also told me that if you have sponginess in your antilock brakes, you can get on an empty road and slam on your brakes hard enough to activate the ABS, and it will blow the bubbles out of the system. I don’t know if that is true or not.

[@psyopus1981]

will this work for a 99 suburban with abs

[@CC-xs1hh]

sounds exactly like my 98 1500, break peadle goes all way down slowly when at a stop, then my break lights quit working, but 3rd light does still work (?) , so not sure it's my break switch, did I you v figure yours out?, thanks

[@KIDZKARTBLDER]

ksmons hay did this work for you .. I am in the same boat . I have done everything you have .

[@MrRgg52]

I lost the rubber cover does it matter or where can I got another one but it's braking thank you so much.

[@hoohoohoblin]

I don’t know if it matters. You’re probably fine if it isn’t leaking. I bet it’s just a dust cover.

[@samsara2024]

This will avoid the soft gummy breaking?

[@hoohoohoblin]

It helps.
