Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Rear Wheels

Tools Required: Jack, jack stands, lug wrench
Loosen lug nuts before lifting the vehicle.
Use the jack to raise the rear of the vehicle and secure it with jack stands.
Remove the rear wheels.

3. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench, brake cleaner
Remove the caliper bolts and carefully slide the caliper off the rotor. Support it with a bungee cord or rope to avoid strain on the brake line.
Inspect the brake pads for wear and replace them if they are below the minimum thickness.
Check the rotors for warping or scoring; resurface or replace if necessary.
Clean the caliper and bracket with brake cleaner. Ensure all moving parts are free of debris.

4. Address Brake Fluid and Lines

Tools Required: Brake fluid, wrench for brake lines
Check the brake fluid for contamination or moisture. If the fluid is dirty, perform a brake fluid flush and replace it with new fluid as per manufacturer specifications.
Inspect brake lines for any leaks or kinks. Replace any damaged lines.

5. Reassemble and Adjust

Reinstall the caliper over the new pads and rotor. Ensure all bolts are torqued to the manufacturer’s specifications.
Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

6. Test Brake Function

Reconnect the negative battery terminal.
Press the brake pedal several times to seat the pads against the rotor.
Test drive the vehicle to ensure that the rear brakes no longer lock up.
