ABS - antilock brakes problem ! Chevy Truck ABS Problems Unwanted ABS Activation
Could be that the callipers are jamming or the wheel is running tight. Check for wheel spin with the front wheels off the ground, they should spin with minimum effort. Could also be something wrong with the master cylinder. It may not be releasing properly and slowly building pressure to lock the brakes. After sitting for a while, it returns to normal position and releases the brakes. Mt Ford had a dud wheel bearing which would intermittently start to seize. When this happened, the anti lock braking system thought that the wheel was about to lock and would throw the brakes on and off without warning... Check your wheel bearings too.
Yes,thank u,Steve F..i had breaks pads all away around,rotors, calibers,drums ....without warning they lock up still,while driving ,after i park for 15min, they release,like if they never lock up....it might happen twice in one month ..thanking its the master cylinder..?
Hi Terry, not sure if the Chev has the same type of master cylinder pushrod,as the Ford, Ive had mine screw itself in which slowly applies pressure to the brakes (The front ones first) This starts to tighten up the front wheels which causes the anti lock brake system to operate. It could be your problem as well.
