Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, brake cleaner, lug wrench.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery (negative terminal) for safety.

2. Remove Rear Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the rear of the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the rear wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Check for wear on the brake pads; replace if less than 3mm thick.
- Inspect rotors for warping or scoring; replace if necessary.
Check Calipers:
- Remove the caliper bolts and take the caliper off the rotor.
- Inspect the caliper for damage and ensure pistons move freely.
- If the caliper is stuck, it may need replacement.
Replace Brake Pads:
- Remove old brake pads and install new ones, ensuring they are seated correctly.
Reinstall Caliper:
- Reattach the caliper over the new pads and torque bolts to manufacturer specifications (typically 20-30 ft-lbs).

4. Brake Fluid and System Bleed

Check Brake Fluid:
- Inspect the brake fluid for contamination; replace if necessary.
Bleed Brakes:
- Using a brake bleeder kit, bleed the rear brakes to remove any air from the system, ensuring a firm brake pedal.

5. Reassemble and Test

Reinstall the rear wheel and tighten lug nuts to the manufacturer’s torque specifications (usually 80-100 ft-lbs).
Reconnect the battery and perform a test drive to ensure brakes function properly.
