Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel covering the affected brake assembly.

2. Remove Brake Components

Brake Caliper Removal
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor without stretching the brake line.
- Suspend the caliper using a bungee cord to avoid stress on the brake line.
Brake Pad Removal
- Remove the retaining clips if present.
- Slide the brake pads out of the caliper bracket.

3. Inspect and Clean

Inspect Brake Pads
- Check pads for thickness; replace if less than 3mm.
- Look for uneven wear or damage.
Inspect Brake Rotors
- Measure rotor thickness with a caliper; replace if below minimum specifications.
- Check for grooves or scoring; if present, consider resurfacing or replacing.
Clean Components
- Use brake cleaner to clean the rotor surface and caliper bracket.
- Ensure all dust and debris are removed.

4. Replace Components

Install New Brake Pads
- Apply anti-squeal lubricant to the backing of the new pads.
- Slide the new pads into the caliper bracket.
Reinstall Caliper
- Carefully position the caliper over the new pads and rotor.
- Reinstall the caliper mounting bolts and torque to manufacturer specifications.

5. Final Assembly

Reinstall the wheel and lower the vehicle.
Ensure all tools are removed from the work area.
