Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Use wheel chocks to prevent the vehicle from rolling.

2. Lift the Vehicle

Sub-steps:
1. Use a hydraulic jack to lift the front or rear of the vehicle as needed.
2. Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Sub-steps:
1. Use a socket set to remove the lug nuts.
2. Take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper by unscrewing the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the brake rotor; support it with a bungee cord to avoid hanging on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Compare the thickness of the new brake pads with the old ones (minimum thickness should be 3mm).
5. Install the new brake pads in the caliper bracket.
6. Reinstall the caliper over the new pads and secure it with the caliper bolts, using a torque wrench to tighten to manufacturer specifications (usually around 30-40 Nm).

5. Clean and Inspect Rotors

Sub-steps:
1. Inspect the rotors for scoring, pitting, or rust.
2. If damaged, consider resurfacing or replacing the rotors.
3. Clean the rotor surface with brake cleaner to remove any contaminants.

6. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from jack stands and remove the jack.
3. Torque the lug nuts to the specified value (typically around 120 Nm).
