Hey Dan. I just wanted to thank you for posting your videos on bleeding GM ABS brakes. I am on vacation towing our camper behind our 2003 Yukon XL and we blew a brake line going to the ABS unit. I ended up buying a pre-made brake line kit from NAPA and changed all the lines (at a camp ground) because they were all pretty crusty. I was having trouble getting the front brakes to bleed and found your videos while search for a way to get the air out of the ABS system. I tried to find a local shop to use a scan tool to cycle the pump but they were all booked with work for a week or more. I drove around and found an old gravel road and repeatedly got the ABS pump to cycle. On the way back to the camp ground I could tell the front brakes were coming back. My wife and I bled the brakes again and immediately got all the air out and thanks again for posting your videos! Vacation can now continue!

Wow man that is crazy! I been dealing with the same problem and one thing I learned from this video. Is PATIENCE! Thanks for the info I been at it for 4 days ! Thanks again

I just did a Chevy Sierra 1500 yesterday and a friend of the guy who owned the truck stopped by with a vacuum pump that was attached to a reservoir to catch the old fluid, and he just connected it to the loosened front bleeders and sucked all the air out through the calipers while just slowly pumped the brake pedal. Tell you what, I couldn't believe how fast it got all the air out of the ABS system, I was just slight of amazed really..... As soon as I get a little extra cash I'm going to get me one of those vacuum pumps.

Nothing is easy anymore, even bleeding brakes. Went thru exactly all of this in my '99 Suburban. What a pain! Thanks for sharing!

I'm assuming you bench bled the master cylinder each time after removing its lines. If not, that's almost certainly the problem. You could have also gotten heinous amounts of air in the ABS module/lines when you changed master cylinders. You mentioned your lines ran dry. Could be that your system is so incredibly dry that the pedal pump methods won't work well (except for MAYBE two man bleeding). The pedal pump methods rely heavily on vacuum in the brake lines when the pedal is released to draw in more brake fluid from the reservoir to the master cylinder. This vacuum in the brake lines is present due to the closed off bleeder in the case of two man bleeding, or fluid friction a la fluid viscosity in the case of open-bleeder-screw pedal pumping (aka one man bleeding). Either way though, if your lines are completely dry, the air in your lines will expand and contract too easily to pull much vacuum, meaning you'll never pull a full fluid charge from the reservoir when you release the pedal. That's all to say you need a fair bit of fluid already in your lines to use the pedal pump methods. Solutions when your lines are completely dry include pressure bleeding (forcing fluid from the reservoir straight through the lines) or gravity bleeding (letting gravity slowly pull fluid from the reservoir down through the lines). Pressure bleeding is a lot faster but requires a compressor/pressurizer tool to supply pressure to the reservoir. Gravity bleeding is slower but cheaper; since you've already been waiting 11 months at this point though, I don't think time is much of a concern for you. XD

I used my friend's scanner to start up the ABS motor it worked. These ABS systems are garbage and not needed. If you brake in the wet and are coming up fast on a car you will hit it. These systems do nothing. I used to drive my old Camero in the 70s and used to go up to the snow and it had no ABS and I never ever had problems. This was just added BS.

Hey Dan. Good video. Thanks for sharing.🍁👍👍

Thank you bro for posting this video it’s A Life saver thanks again..

There is some sort of valve that only comes into play when you are pumping up the brake pedal to get your 1-2 emergency brake uses when you are driving and get a brake line torn off or something like that. It is this valve that can thwart you when you are buddy bleeding the brakes, causing you yo have to do a bunch of cycles, especially if you have a bunch of air in the lines from replacing lots of brake system. If instead of going pump pump pump hold, you pump, then slide your foot to the side, like you are dumping the clutch, that faster return on the pedal helps the air bubble get down through the u bends in the brake lines, instead of just tromboning back and forth. Works on hydraulic clutches too, even ones like ford rangers where many good mechanics say you have to bench bleed them, you can bleed them on the vehicle. It's like you were pushing a toy train into a tunnel, normal stomp stomp stomp method, you are grabbing a train car in the middle of the train, shoving whole front half of train into the tunnel, but then pulling it back out again cause you aren't letting go of that middle train car. With the side step method, you shove front half of train into tunnel, then lifting up your hand, grabbing the caboose, and shoving the second half of the train into the tunnel. I'd been a pro mechanic for almost 20 years before this crazy old meth addict mobile mechanic showed me this trick, he was literally the shadiest mechanic I've ever met, hah, but I will always be grateful to him for teaching me that trick.

Thanks for your information 👍

Thanks for the video! I have 2003 GMC. About to do brakes and seen the video as I was scrolling. I replaced front calipers last year. Doing rears this time around. Skirts are rotted and my E brake is no good. SO.. toss all that in the wash basket and I'm contemplating doing the lines and everything. Correct me if I'm wrong but the envoys had ss brake lines from oem. SO hopefully I need not mess around to much with it. - I too wrestled with the ABS module and valve a while back and ABS light just came on after something like 5 years so. Again thanks and wish me luck ✌

If your Hub's got Holes rather than sticky out studs, put the Wheel Bolts in; else you'll bend the little screw that holds the Disc on when you hit the Brakes. Cheers for the help

There is 2 bleeders on the abs module. 1 for the front wheels and 1 for the rear wheels. But there is a procedure to do it. Google how to bleed abs to your vehicle.

Tip- I was able to bleed the abs on my 1995 GMC Sierra 2500 by starting the engine and jumping the OBD1 ports "A" and "H" periodically to make the ABS motor run while I pumped the brakes. Worked great and the brake warning light finally shut off after I had to replace a line to the rear passenger side.

I had a bleeder that wouldn't flow once. In my case, it was a blocked bleeder screw. Corrosion or debris had blocked the small bleeder tube in the screw. I used a paper clip to push around in the bleeder hole to clear the blockage and it worked fine after that.

Thank you very much!

Was having an issue of my brake pedal going down to the floor after a local mechanic fixed my brake issues of one sided brake pad got eaten more than the other side. So i did the full brake method and it fix the issue. I knew my abs was not an issue as im able to brake normally but after certain time the pedal went to the floor and if i were to send it to the local mechanic, they would have told me to replaced the parts which would cost me more money when they're the one causing the issues. Thanks again for the video, save me so much.

You should open the bleed nipple with slight pressure on the pedal, press the brake pedal all the way down then close the nipple before allowing the pedal back up. The sealed calliper allows the master cylinder to develop the vacuum to suck in a full charge of fresh fluid. Not closing the bleed nipple reduces the 'suction at the master cylinder and allows fluid to pass forward and backward and can allow even more air in. One way to make this sort of job easier is with a little vacuum hand pump bleeder, it simply draws fluid from the reservoir through the master cylinder and out through the calliper taking the air with it. Also although some do it it's not a great idea to bleed a calliper without a pipe attached sufficient to allow a little fluid to rise out and show air being extracted, it also keeps brake fluid off paint etc.

@johnronkainen9445

Ай бұрын

I've had problems with vacuum bleeders just drawing in air through the bleeder screw threads instead. The stream of air bubbles doesn't get into the caliper per se, but it makes it harder to draw fluid out of the line or see how much air is actually coming out of the line when it's flooded by introduced air. Attaching a vacuum bleeder while pumping the brakes would be a decent way of keeping constant vacuum on the brake lines if you're bleeding them yourself, though.

Fabricate a pressure bleeder from a garden sprayer .... easy and cheap and works like a dream. replace rubber hoses too.

There is no problem. It's a open front differential, that's exactly how it's supposed to be. Path of least resistance was the right front wheel (unless the right front wasn't spinning), so that wheel spun while the driver's side didn't. Your rear end will do the same if you don't have the G80 spec rear differential on your glove box build sheet

Theory qualification here, I am working on this issue as well on my Tahoe that blew a wheel cylinder seal At 11:00 , you pumped the pedal and suddenly voila. When the system has a safety mechanism which is a shuttle valve moving across a bore path (it's called a proportioning valve), the one half of system isn't getting flow. Engineered to do that, in compliance with NHTSA regulations, and that is why you can get the vehicle to stop when you blow a line. To return the shuttle valve to center, you have to pound the pedal (which is what you repeatedly trying to do), and release pressure on the opposite side which is holding pressure. Eventually, the darn contraption goes back to center, and allows the fluid flow to the side which blew out originally. We way over think this stuff. So knowing you blew a line, resolve proportion valve position (back to center), bleed the entry fittings into the ABS module, and see if you can cut the work time way down to a simple brake bleed.

Follow up. I had mashed the pedal down and rapidly opened the side of the system (front) that was bled and holding pressure. That did fix the combination valve on the 96 Tahoe which is built into the Kelsey Hayes ABS unit. I had also used computer to open ABS but was unsuccessful with only that procedure to get any fluid to the back half (wheel cylinder blew on my vehcile). Hope these comments save the next person a lot of aggravation at a task that isn't so difficult once you understand the safety features of the vehicle.

There’s a screw in fitting you have to use on that proportional valve to keep it from activating and make bleeding brakes easier.

Look up a tool called “fender lizard”. I seen it used and it’s pretty cool.

Good video. Even liked the little jokes. I have a suggestion though. Next time you use a self bleeder like that try raising the bottle above the bleeder valve so the air won't want to go back into the caliber. It will want to go up into the bottle. I never see people do that and it seemed like people should. I haven't had a problem with it in the millions of years I have been bleeding brakes.

The bleeder valve could be clogged. Remove the bleeder valve and clean out the hole in it.

So did you do the video on the driver front wheel not turning in 4wd? Been hunting for it. Thanks

The easiest way to bleed an ABS module is to apply the brakes on a slippery surface like grass on a wet or rainy day. Fast, simple, effective. It usually has to be cycled only once. You must have some pedal in order for the ABS module to activate. If you have no peddle (too spongy) this method will not work. But man, is it slick!!! Pun intended.

@josepeixoto3384

Why the front wheel was not turning - there are different options of AWD/4WD. Each axel has a differential (which may be blocked on some of cars). Some may have a differential between the axels. If this is the case, with all wheels in the air you may get only one wheel rotating while all four are engaged. I have quite a number of questions about what you were doing, but I guess the most important is how do you know which wheel ABS is activated on when you hit the brakes and all the wheels are in the air? On my (passenger) car I was doing them one-by-one, to make sure that all are done. I guess this may be the reason why you had to use the fancy tool after all.

Help me out man at around 11:00 min in the video you had trouble getting the stream out from that specific bleeder valve, how did you manage to get that stream? I have oil coming out the rear bleeder valves but just by drips no streams

one front caliper has sticky pins, causing pad drag, stopping the right front wheel against the differential. one tire spins.

Maybe the inside of the line is collapsing won't let the brake fluid come back and release the Pistons out of the calipers

One of your front wheels is spinning because it’s not a locking front differential it’s open so one side is spinning in the other side is doing nothing until you have traction or both tires on the ground

Don't like color of the fluid, they make a positive pressure system, but I don't know if it works with ABS

2 things: music was too loud, 2. check valve bleeder valves are avail, makes one man operation easy. Turn 1/2 turn, fluid or air comes out, not back in. I'm used to working alone, those help.

I vacuum bleed my brake systems by sealing off the master cylinder reservoir and using an A/C system vacuum pump. This pulls all the air back out through the master cylinder and works much quicker and easier. This evac and fill method is how the car manufacturers do it (in about 30 seconds).

Yep..just enough info to sound good but no idea how to do it..not enough info where to hook up where air goes....grief.

Probably it’s due to traction control.

Could have plugged bleeder on that drivers side

Wich model scanner?

can i bleed it by hard connecting its relay?

That line gets clogged and doesn't let fluid come through it been threw that usely the rubber line lets fluid out but won't let it return back to master cylinder
