Rear Brakes Locking Up Yahoo Video Search Results What causes rear drum brakes to lock Need Help With Rear Disc Brakes Locking Up Heating Up Hot 1999 2006 2007...

ALL brakes locked up, or just rear? Rear could mean differential is locked up...Sounds more likely while driving it, as cars now have a front or rear valve so all brakes are not lost at one time..

Anti-Lock Brake systems are all essentially the same they will prevent the driver form applying 100% Brake pressure and locking up the wheels while driving. The ratchet the pressure more slowly to prevent the car from skidding. Our first reaction in an emergency is to slam on the brakes and that is 90% of the time not the right action. So Anti-Lock brakes are designed to prevent this unwanted skid.

I suspect that you have front disc and rear drum brakes.You did not say which of your brakes are locking up. I suggest that if your front brakes are locking {skid} that means your rear brakes are not engaging. If your rear brakes are locking {skid} then I suggest you have problems with park brake or brake fluid leaking onto the rear shoes.
More info would help me help you. I will check back soon.
