 Subject: Temporary Brake Failure!?
IP: Logged
Message:
I was coming to a stop at a light that was turning red. The road was wet and suddenly lost my brakes. I pumped the brakes at least 4-5 times and recoved them before flying through the intersection.
Not sure if I just lost braking or if it locked up and didn't relase. I had the music up and didn't hear skidding. Anyway, everything after that was fine. Could re-create the problem. I remember feeling the ABS pulsing but no stoppy.
Could it be a warning of a master cylinder failure? No leaks in hoses, calipers or any other visible problems. Good pads, everything. Any suggestions?

I ALSO HAVE A PROBLEM WITH MY ABS ON MY TRUCK. WHEN I HAVE A SUDDEN STOP WHERE THE ABS SHOULD KICK IN, IT FEELS LIKE YOU ARE TAKING YOUR FOOT ON THE BRAKE THEN THERE IS A LOUD THUD THE BRAKES GRAB THEN THE BRAKES RELEASE AND IT REPEATS TILL THE TRUCK COMES TO A STOP. IT TAKES MORE STOPPING DISTANCE TO GET THE TRUCK TO STOP WITH THE ABS ENGAGED AS OPPOSED TO STEPPING FIRMLY WITHOUT ACTUATING THE ABS. I STILL HAVE NOT BEEN ABLE TO FIGURE OUT WHATS GOING ON. DOES IT SOUND LIKE YOUR PROBLEM ??

Doesn't really do the same for me. I have a 99 Dakota 4x4, 5.2 v8. As soon as the truck starts to slip the ABS kicks in right away regardless or slamming it or pressing hard.
So far just once it felt like it released and had no braking at all except for a slight pulsing. I'm pretty sure I was sliding on the wet pavement but couldn't tell over the radio. Hope this doesn't happen with a vehicle in front of me or even worse a kid on a bike or something.
The master cylinder is around $120 - $300 CDN approx. where I am so I might try that. Don't want to take a chance.

Stepping firmly is actually what engages the ABS. Trying to pump the brakes in an ABS equipped vehicle causes the system to work impropery. You sure you're keeping that pedal planted when you stop suddenly?

On my 2002 QC with rear ABS only when you slam on the brakes and the rear ABS does its job the pulsations are very long. The ABS system on these trucks are not the same as found on other vechicles. The normal ABS has a high pressure pump turning on and off very quickly and you would feel the pulses happening very quickly, but on these trucks with rear ABS only when the ABS senses a lockup on the diff then it dumps the pressure from the rear brakes untill it senses the diff rotating again and then it will allow pressure back to the rear brakes. I have felt my brakes pulse on and off over a few seconds and the vechicle actually rolls forward a few feet untill the rears come back on again. It is very scary slaming on the brakes and having the ABS actually let you roll three to four feet while it is releasing and reapplying the pressure to the rear wheels. It feels like the pressure is also being reduced to the front brakes but maybe I am feeling how much the rears actually apply as they are turned on and off.

My '02 QC scared the crap out of me a few times when the ABS kicked in. It is a very long pulse and lets go of the rear brakes completely. Part of the problem is that there is way to much rear brake bias. They do this to account for a fully loaded bed, but how often is that? When the rear brakes let go with the ABS, you lose what seems to be 70% of your stopping power.
My solution was to put Hawk brake pads up front. This put more of the braking bias to the front. It is still not as much as I would like but it is a great improvement. This way I get much more braking out of the fronts before the rears lock up, plus you are left with more braking when the rears let go.

THE SENSATION IS EXACTLY WHAT YOU DESCRIBE. THE ABS ACTUATES AND THE BRAKE PEDAL IS STILL FIRM BUT IT FEELS LIKE YOU ROLL FORWARD WITH LESS BRAKE PRESSURE APPLIED. IS THERE A FIX TO CHANGE THE PROPORTIONING VALVE WITH AN ADJUSTABLE ONE ?? OR IS THERE A FACTORY ADJUSTMENT TO THE SYSTEM ?? THANKS

I never looked into whether there is a way to adjust the bias on the master cylinder. Check it out and let me know what you find out.

I know my truck isn't just rear ABS. I didn't realize a lot of models were only rear wheel. Good to know. So I guess I lucked out to have the extra option... maybe. :) I've tested the ABS quite a bit on the back roads when wet and works quite well. No lengthy coasting or slow pulsing. Just once, I lost my breaking... and its buggin the hell out of me trying to remember details.. Sometimes when its cold I'll back out of my drive way and then drive 2 house lengths to the stop sign and lightly press the breaks and almost have wheel lockup. The woman always gives me s--- for it but I don't slam them.
I'm pretty positive they locked and got stuck. Thinking about the ABS pulsing, maybe it wasn't able to release.
I'm not sure of any adjustments to master cylinder or any other. Someone mentioned to me about a firmware update since some of it computer controlled. Maybe something of this sort exists, and if so where would I find this?
So far haven't found anything relating to this problem except for full brake failure.

I've experienced the same problem as described by others on my 02 QC 4x4, with rear only anti-lock brakes.. I just bought this truck about a month ago..
So far I've had the dealer install new rear drums, and flush the brake hydraulic system.. I also paid for new front rotors and Hawk pads to be installed.. My next step is to install a manually adjustable brake proportioning valve.. I believe like was mentioned before, that there is too much rear brake pressure bias..
BTW.. This site is really really cool.. Glad I found it..

I have a 2006 Dodge Dakota SLT, for the last months now my abs
light and brake light are on and stay on and my brakes a “spongy”..
It also has blown out 2 wheel cylinders. I noticed my rear brake
shoes need replace but they aren’t terribly bad. My front brakes
are new but they aren’t engaging nor is my emergency parking
park. I have replaced the master cylinder as well and no
difference. My brake booster gets air so I believe that is working.
Any suggestions on what it could be or possibly be?
