Question about 2000 GMC Safari

2 Answers

Most-not all- times that I stop, the ABS kicks in. HELP!!

When I stop at a light, or pull into a parking space, the ABS system kicks in and the van won't stop. There are no dash lights that come on when this happens, and it is happening more frequently, I can almost count on it every time I stop now. When I feel it start to happen, if I let go of the brake and then reapply it, the brakes will work normally. Lately it has been getting so bad that the brakes won't release sometimes and kind of lock up and I go an extra 10 feet -- very dangerous! I have had about 4 different people look at it and some say it's the ABS module, but they aren't so sure because of the light not coming on, and the ABS still works. I have also heard it could do with the individual sensors on the wheels, and one person even said something about the power steering pump being involved. A tire place hooked up their computer when they were driving it, and their computer did not register a problem. I really need to get this fixed, and I don't mind paying for the problem, as long as it's the right thing.

    There was actually a recall for this. Go to your local GM dealer and have them check your VIN for a recall. If not under recall get out of there its easy to repair yourself don't let'em fool you. Remove the front pads caliper and rotors. Locate the abs sensor mounted to the wheel bearing assembly by a small socket head cap screw (Allen wrench). Remove the bolt and softly gently/wiggle the abs sensor around until it pops up out of the hole. some will break, which is why it would be nice if the recall applies to your vehicle that way if they break gm replaces. Once you get both sides removed, clean the mounting surface of all rust or build up with w-d 40 and small steel toothbrush then wipe off excess with clean rag and mild soap and warm water, dry completely make sure no spray residue exist on parts, Next apply a thin layer of lubricant grease to prevent future rusting and reassemble. The rust build up under the sensor is causing the angle to change resulting in inaccurate wheel speed readings in the abs module your abs module will interprets this as a wheel is either slipping or skidding and applies your abs. This should make you happy with no more irritations.

99 caravan 3.3 no abs brakes. I have replaced a bad master cylinder and all 4 rusted brake lines. The ABS brake warning light is not on. The van does not pull to one side.

Something is wrong with your statement
it is a 99 caravan 3.3 no abs , then you are on about abs light pump etc
the abs pump only works when the master cylinder is under pressure and that pressure is suddenly reduced by the sensor reading a locked wheel and a valve is opened to release line pressure to that wheel As soon as that wheel starts to turn, the valve closes
while the wheel is stopped and that valve is open , the abs pump kicks in to maintain line pressure otherwise the brake pedal would go to the floor
master cylinders work through a. abs unit and not because of it so if the master cylinder becomes faulty, the abs pump will not operate until a wheel stops turning as there is no line pressure to stop a wheel turning
the abs light may not be on because there is nothing to operate the system to put it on

Well, it could mean that the emergency brake has not been fully released.The ABS system light is on if something has occurred within the ABS system. Something faulty may have happened there, get it checked out!

First thing with brakes is to check the lining thickness. You can usually see the fronts through the wheel, or look underneath. If you have drum brakes in the back there may be a rubber inspection plug.

But if linings are ok, another risk is wheel bearings. You would then feel it as a vibration in pedal, and through steering wheel if a front bearing.

With the light, have the ABS code read with a ODBCII module. Autozone can do this for free.

check the rotors for scoring,worn rotors will "feel"like the abs is coming on due to the vibration caused.and will account for the extended stopping distance.
