Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel covering the affected brake assembly.

3. Remove Brake Components

Brake Caliper Removal:
- Use a socket set to remove caliper mounting bolts.
- Carefully slide the caliper off the rotor and suspend it with a bungee cord to avoid strain on the brake line.
Brake Pad Removal:
- Remove the old brake pads from the caliper bracket by sliding them out.
Brake Rotor Removal:
- Remove any retaining screws if applicable.
- Slide the rotor off the hub.

4. Inspect and Replace Components

Brake Pad Inspection:
- Measure the thickness of the brake pads; replace if less than manufacturer specifications.
Brake Rotor Inspection:
- Check for deep grooves or warping; replace if necessary.
Caliper Inspection:
- Ensure the caliper piston moves freely; replace caliper if sticking is observed.

5. Install New Components

Install New Brake Pads:
- Apply a thin layer of brake grease to the backing of the new brake pads.
- Slide the new brake pads into the caliper bracket.
Install New Rotor (if replaced):
- Position the new rotor on the hub, ensuring it is flush.
- Tighten any retaining screws.

6. Reassemble Brake System

Reattach Caliper:
- Carefully slide the caliper back over the new pads and rotor.
- Secure the caliper by tightening the mounting bolts to manufacturer torque specifications.

7. Final Checks

Reinstall the wheel and lower the vehicle.
Pump the brake pedal several times to ensure pads are seated properly.
