Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and use wheel chocks.
Tools Required: Jack, jack stands, socket set, torque wrench, brake cleaner, caliper tool.
Safety Warnings: Always wear safety glasses and gloves.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Use a caliper tool to measure the thickness of the brake pads; they should typically be at least 3mm thick.
- If they are worn down, proceed to replace them.
Replace Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and suspend it without putting stress on the brake line.
- Remove the old brake pads from the caliper bracket.
- Apply brake grease to the back of the new brake pads to reduce noise.
- Install the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for scoring or warping using a visual inspection.
If replacement is required, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new rotors and torque to manufacturer specifications.

5. Reassemble Brake Components

Reinstall the brake caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer torque specifications.
Reinstall the wheel and torque lug nuts to specifications.

6. Final Checks

Lower the vehicle and pump the brake pedal to ensure proper pad seating.
Check brake fluid level in the reservoir and top off if necessary.
