Question about 1997 GMC Sierra K2500

Anti-lock brakes come on just before I stop when payment is dry

Replaced the front rotors and pads on my 1997 GMC K2500 truck. I do not have an ABS light on, but just before I stop the anti-lock brakes come on every time and it takes me a couple more feet to stop. I have disassembled and re-assembled everything and I do not see a problem. I have bled the entire system thinking that might be my problem to no avail. Please help!!!

I have a 1997 chevy k2500 and had the same problem. My fix was where the abs sensor goes into the housing. There was a little bit of rust that pushed the sensor away from the housing just a little which caused a false reading. I removed the sensor and used a roloc disc to polish the metal and reinserted the sensor. I have had no problems since.

Did you check the alb sensor? You might also have the "return spring" stuck in the emergency brakes. Sometimes they break causing the brake to lock, which in turn activates the alb. Also, check the brake oil level, in some cars alb dont work properely if the oil level is too low. Good Luck

Check the wheel bearings for serviceability. Check the pad thickness on the discs. I suspect a failed wheel bearing allowing the disc rotor to touch the ABS sensor ring and the calipers.

My abs light on my 2000 buick lesabre will not shut off i have replaced rotors and pads what could the problem be


The warning light indicates that there is a malfuction in the anti-lock Brake System (ABS). Normally the system will then cease to function so you have a conventional braking system with no anti-lock feature to engage if you lock up the wheels on braking.

This ABS fault warning has nothing to do with the condition of the pads and rotors so renewing them, which is essential for good braking performance, will not solve the problem.

You will need to take the vehicle to a mechanic with the correct equipment to diagnose the cause of the ABS warning. It may be as simple as a failed ABS sensor (or sensors) and that is what I would be checking first.

It is quite safe to drive the vehicle with the ABS disengaged because your brakes will operate normally. What you don't have is the ABS kicking in to release the brake pressure temporarily in the event you brake hard and lock up any of the wheels.

1997 suburban C1500. I replaced the Front pads


Hi,
You will have to check each brake caliper for pressure when the brake pedal is applied. You may have a sticking piston in one of the brake calipers.

This will cause a spongy pedal.

Hope this helps,let me know how you get on.

Thanks

make sure you are bleeding them by doing them as an abs system,do the right rear then the left front,then the left rear then the right front,the opposite wheels are how the system brakes.

you need someone to scan it for codes but it sounds like the speed sensor for one of the wheels is droping the signal to the abs unit at lower speeds they can see that with the data stream with a scanner

Anti-lock brakes come on just before I stop.


It might be a ALB sensor. Did you check to see if the sensor is operational? Its the cheapest place to check.

Anti lock brake light on


It is most likely a bad front wheel speed sensor.Your sure abs rings were on back of rotors?It is going to be next to impossible to fix without getting the code with a scanner
