What to Do If the Right Rear Wheel Brake Locks Up?

[MacSamuel]

If the ABS is not installed and the brake pedal is pressed hard while driving, the wheel speed will rapidly decrease. When the braking force exceeds the friction force of the wheel, the wheel will lock up. By continuously monitoring the speed of each wheel through speed sensors installed on the wheels or drive shafts, the computer calculates the current wheel slip rate. A decision is made to increase or decrease the braking pressure, and the controller instructs the regulator to reduce the hydraulic pressure in the wheel's brake cylinder, thereby decreasing the braking torque. This process can occur 5 to 10 times per second, ensuring the wheel remains in a rotating state while maintaining maximum braking torque.

If the right rear wheel's brake is locked up, I've dealt with this issue many times. First, never force the car to drive, as it could cause tire wear or even a fire. Safely pull over to the side, engage the handbrake, and turn on the hazard lights. Then, check if the brake caliper is rusted and stuck—common in humid conditions. Lightly rev the engine a few times; sometimes this can loosen it. If that doesn't work, try gently tapping the caliper area with a rubber hammer, but be careful to avoid damaging any parts. After a temporary fix, immediately drive to a professional repair shop to replace the caliper or clean the piston—don't delay, or it might lock up completely next time. For regular maintenance, check the brake fluid level and caliper lubrication every six months to prevent similar issues. Always remember, safety comes first—a locked brake makes steering difficult and increases the risk of accidents.

I once experienced a situation where the right rear wheel locked up, which really startled me. First, I calmly pulled over, turned off the engine, and waited a few minutes for the brake system to cool down. Then, I tried slowly reversing or moving forward to see if the stuck part would loosen. If that didn't work, it might be due to brake pad adhesion or piston issues. In my case, the mechanic said corrosion in the wheel cylinder was the main cause, especially after prolonged parking. The repair wasn't complicated—just replacing the parts, costing a few hundred yuan. I recommend avoiding hard braking when parking and using the parking gear more often to reduce the risk of brake rusting. If a lock-up occurs, don't panic; seek help immediately or drive slowly to the nearest repair shop to prevent wheel hub damage. Remember to have the technician focus on inspecting the rear brake system during maintenance.

A stuck right rear brake is quite common. First, safely park the car without moving around, then I checked the brake caliper—if there's rust, gently tap it a few times or try loosening the caliper bolts with a wrench. If the tire or wheel hub is overheated, wait for it to cool down. A temporary fix is to lightly rev the engine to get the wheel moving, but only try this at low speeds. If it doesn't work, don't force it—call a tow truck or drive to a repair shop immediately. The main causes are usually expired brake fluid or a seized caliper, which can be fixed by replacing the caliper. When I was learning to drive, my instructor taught me that preventive measures include regularly changing the brake fluid and avoiding always pressing the brake pedal fully when parking. Safety is the top priority—driving with a stuck brake is dangerous and damages the car.
