2002 Chevy Silverado 1500 Where is the anti-lock brake sensor?

I do believe it is rotors all the way around. I has a 2002 chev silverado 1500 4x4 and thats what was on my truck.

The brake rotors are warpped [ the pulsation ], The pads may be worn out, and-or have a frozen caliper causing the loss of braking power.

jack up pull wheel, pull brake caliper and bracket, take nut off axle in center of bearing on back side where axle goes in should be 4 bolts make sure to dis connect abs sensor cause its comin with the bearing that should be bout it some times they come out hard but the will come out

Your truck is equipped with RWAL or rear wheel anti-lock. This just worked on the rear brakes(duh) but the speed sensor was taken from the speedometer drive at the transmission tailshaft, and would allow one rear wheel to lock as long as the speedo kept turning. Later models were improved with wheel speed sensors at each wheel.

Possible it is the ABS wheel sensor. GM had a recall for this.

From pads may be low causing the rear brakes to over brake and the anti-lock kicks in. Could be a sticking caliper piston and last the proportioning valve may need bleeding as it is offset.....

Might work!!!! get under the front end and try to pull the bonnet release cable when open take the live off the battery and keep arking it off the battery may open the doors if central locking.

Sounds like a faulty wheel sensor. I would suggest a trip to the repair shop.

plug it back in and bleed your brakes dude.

You most likely have a wheel speed sensor dropping out this would make abs system think one wheel is locking up and therefore activate. this usually will happen rt before you stop at around 5mph or so.Also if you have bigger tires than factory and have not had abs programmed for this size it can aggravate it
