* Brake caliper piston seizure: The brake caliper piston can seize due to corrosion or a lack of lubrication. This can cause the brake pads to stay in contact with the rotor, causing the brake to lock up.
* Brake hose failure: The brake hose can fail due to age, wear, or damage. This can cause the brake fluid to leak out, reducing the pressure in the brake line and causing the brake to lock up.
* Master cylinder failure: The master cylinder can fail due to a leak or internal damage. This can cause the brake fluid to leak out, reducing the pressure in the brake line and causing the brake to lock up.
* Proportioning valve failure: The proportioning valve is responsible for distributing the brake fluid pressure evenly to the front and rear brakes. If the proportioning valve fails, it can cause too much brake fluid to be sent to the rear brakes, causing the rear brakes to lock up.
* Wheel bearing failure: If the wheel bearing fails, it can cause the wheel to wobble. This can cause the brake pads to rub against the rotor, causing the brake to lock up.
To resolve this issue, you may need to replace the faulty components such as the brake caliper, brake hose, master cylinder, proportioning valve, or wheel bearing. It's important to have a qualified mechanic diagnose and repair the issue as soon as possible to ensure safe braking and vehicle operation.
