What should I do if my brakes lock up while driving?
I’d go with: Drain all brake fluid. (You should change boiled-up brake fluid) Service the brake caliper. (Change rubber parts, o-rings, clean off rust, silicone paste for cylinder and guides, copper paste on pads). Change both rear brake disks. (Most likely you overheated that locking brake disk) Refill brake fluid, bleed brakes.
What causes one set of brakes to lock up?
If just one set of brakes locks up, the cause may lie within a caliper piston that is dragging, ultimately causing friction and overheating the brake fluid that then throws off the in-line pressure of that particular brake system.

Why do my brakes keep locking up?
- loss of traction between the tire tread and road surface when stopping on wet or slippery roads causes brake lock-up.
- Mechanical Failures.
- Brake Calipers.

- Wheel Speed Sensors and Wheel Bearings.
- ABS Computer.
- Driver Reaction to Road Conditions.
What causes my rear drum brakes to lock up?

Why do rear wheels lock on braking?
A bad brake system proportional valve delivering equal fluid pressure to the entire brake system can cause the rear wheels to lock-up during heavy braking. ABS only: Brake fluid contaminated from moisture can damage the ABS pump. A failed ABS pump will cause poor braking performance as well as brake lock-up.
What causes front brakes to lock up?
There are several possible causes for the right front wheel to be locking up: (1) Contaminated brake lining: fingerprints, grease, or oil on the front brakes on either side of the vehicle can cause one wheel to grab before the other. (2) Damaged brake hose.

What causes rear drum brakes to engage too soon?
If the parking brake system is not de-adjusted properly before the brake shoes are adjusted it will cause the rear brakes to engage too soon. This is especially true of vehicles equipped with duo-servo rear drum brakes (see Figure 61.1).
Why does my car lock up while driving?
I have already popped off the wheels and did some test by applying brake pressure and being sure that the caliper would release afterwards, and it does. But driving it is a whole different story, the pedal will start getting harder and harder, and the car will start feeling slower and slower, then bam the car will just lock up!!

Why does my car lock after a few miles?
It is no longer an intermittent issue. The brakes lock after a few miles of driving, every time. I also noticed the brake gets so sensitive that the car stops before the brake travels far enough to activate the brake light switch. I flushed the brake fluid and bled all four brakes yesterday.
If the parking brake system is not de-adjusted properly before the brake shoes are adjusted it will cause the rear brakes to engage too soon. This is especially true of vehicles equipped with duo-servo rear drum brakes (see Figure 61.1).
