Question about 2002 Buick Rendezvous

My abs brakes are kicking in when I go down a hill or turn my wheel. Normal stopping is fine but slow to stop I hear a internal rubbing sound and then the brakes engage. No light on yet. What might cause this?

SOURCE: My ABS brakes are kicking in when I go down a hill

A wheel speed sensor is most likely the cause, sometimes one wheel sensor might be a little off in its values and the car thinks the wheel is skidding so it activates the anti-lock system. Problems seems to occur more often at slow rate of speed. When you turn the steering wheel it changes the rotational speed from one wheel to the other and the abs computer thinks it's moving at a different rate of speed, normaly the system will compensate for this, but again if the sensor is off a bit and it excedes it's maximum allowance it will activate the system.The sensors are built into the hub assembly on this car. The rubbing noise sounds as if the abs system pump is comming on.( this is normal if in fact this is what's going on with your car). The reason no light yet, is because as far as the abs module is concerned everything is working properly and it's just doing what it's supposed to do.

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

Abs light is off and abs kicks in under normal braking then light comes on and brakes are normal. 2002 pontiac montana


there are abs sensors mounted to the braking system on the wheels, one of them is shorting out, to verify, remove the abs fuse from the fuse box under the hood, test drive the vehicle, it should run fine without the abs system. have these sensors cleaned or replaced.

this is normal, all abs systems are full time, if they weren't then the systems would be useless.

Sounds like a bad ABS sensor in the system. The quick fix is to locate the ABS fuse in your fuse panel, remove this fuse and abs is disabled. Your brake will function normal and it is safe to drive w/o abs until you can have it checked out, keep in mind you will lock you brakes under heavy braking conditions.

hope this helps
