Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical issues.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Remove the wheel lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Check both inner and outer brake pads for uneven wear.
- If significant wear is found, proceed to replace the brake pads.
Remove Brake Caliper:
- Unbolt the caliper using the appropriate socket size.
- Carefully slide the caliper off the rotor and secure it with a bungee cord to avoid stress on the brake line.
Remove and Inspect Brake Pads:
- Slide out the old brake pads from the caliper bracket.
- Clean the caliper bracket using brake cleaner and a wire brush.
Replace Brake Pads:
- Insert new pads into the caliper bracket.
- Apply a thin layer of brake lubricant on the back of the pads to minimize noise.

4. Reassemble Braking System

Reattach Caliper:
- Position the caliper back over the new brake pads.
- Torque the caliper bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).
Reinstall Wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and then torque the lug nuts to the specified value (usually 100-120 ft-lbs).

5. Final Checks

Reconnect the negative battery terminal.
Check brake fluid level and add if necessary.
Pump the brake pedal a few times to ensure proper brake engagement.
