Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Wear safety glasses and gloves.

2. Remove Wheel

Loosen lug nuts using a lug wrench.
Raise the vehicle with a jack and support securely with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Remove Caliper

Locate the brake caliper and inspect for leaks or damage.
Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the rotor; support it using a bungee cord to avoid stress on the brake line.

4. Replace or Repair Components

If brake pads are worn unevenly, replace both pads on the affected axle.
If the caliper is found to be malfunctioning, replace it with a new or remanufactured caliper.
Check and replace the brake fluid if contaminated; use DOT 3 or DOT 4 fluid as specified.

5. Reassemble

Slide the caliper back onto the rotor and secure it with mounting bolts; torque to the manufacturer’s specifications (typically 20-30 lb-ft).
Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (usually 100-110 lb-ft).
Lower the vehicle back to the ground.

6. Brake System Bleeding

Bleed the brake system to remove air bubbles. Start from the wheel farthest from the master cylinder (usually rear passenger side) and work toward the closest (front driver side).
Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve.
