What Causes Rear Brakes To Lock Up. I was have some problems with locking up then but after the change was good for a while but I sat the for a while cause of a pinion seal leaking. When there is too much pressure on the brake pedal the reaction that happens within the inner components will cause the tires to remain still and slide across the surface of the road losing all traction.

Why Brakes Lock Up. In this video Ill show you how to diagnose a locked up brake caliper andor dragging brakes for one wheel. A defective cylinder can cause brake lock up.
Then if you let it sit for about 5 hours the pressure bleeds back to the master cylinder and the brakes release.
When doing a rear brake job change all of the mounting hardware and springs with new ones. The master cylinder system relies on seals leading to the brakes to maintain. When it is functioning correctly the ABS system is designed specifically to prevent the wheels from locking up during heavy braking preventing loss of traction. Then if you let it sit for about 5 hours the pressure bleeds back to the master cylinder and the brakes release.
