Solution

1. Preparation

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

2. Remove Wheel

Loosen lug nuts with a lug wrench before lifting the vehicle.
Use a jack to raise the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Measure the thickness of the brake pads. Replace if below manufacturer specifications.
- Check the rotor surface for grooves or warping. If warped, proceed to replace the rotor.
Remove Brake Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully lift the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Replace Rotors:
- Remove the old rotor by unscrewing any retaining screws if present.
- Install the new rotor, ensuring it is seated properly.
Replace Brake Pads:
- Remove old brake pads from the caliper bracket.
- Install new brake pads in the caliper bracket, ensuring proper alignment.
Reinstall Caliper:
- Compress the caliper piston using a C-clamp to accommodate the new pads.
- Reattach the caliper to the bracket using the mounting bolts and torque to manufacturer specifications.

4. Reassemble Wheel

Place the wheel back onto the hub.
Hand tighten the lug nuts, then lower the vehicle and torque the lug nuts to the specified value.

5. Test Drive

Lower the vehicle completely and conduct a test drive to ensure the issue is resolved and brakes function correctly.

Tools Required:

Lug wrench
Jack and jack stands
Socket set
C-clamp
Dial indicator gauge (for rotor inspection)

Parts Required:

Brake pads
Brake rotors (if warped or worn)

Estimated Repair Time: 2-4 hours

Safety Warnings:

Always ensure the vehicle is securely lifted and supported on jack stands before working underneath.
Allow the brakes to cool before inspecting to avoid burns.
