Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, socket set, brake cleaner, safety goggles, gloves.
Lift the vehicle using the jack and secure it with jack stands. Remove the wheel using the lug wrench.

2. Inspect Brake Pads

Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully slide the caliper off the rotor and support it without straining the brake line.
3. Inspect the brake pads for wear; they should have at least 3mm of friction material. Replace if worn down.
4. Clean the area with brake cleaner to remove dust and debris.

3. Inspect Brake Rotors

Sub-steps:
1. Check the rotor surface for scoring or grooves. If surface damage is present, resurfacing or replacement is necessary.
2. Measure rotor thickness with a micrometer. Ensure it meets manufacturer specifications.
3. If the rotor is below the minimum thickness, replace it.

4. Caliper and Fluid Inspection

Sub-steps:
1. Inspect the brake caliper for leaks or damage. Replace if necessary.
2. Check the brake fluid level in the reservoir. If low, top off with manufacturer-recommended brake fluid.
3. Inspect brake lines for any signs of wear or leaks.

5. Reassemble Components

Sub-steps:
1. Reinstall the caliper over the new or inspected pads and rotor.
2. Torque caliper bolts to the manufacturer’s specifications (typically around 20-25 lb-ft).
3. Reattach the wheel and lower the vehicle.
4. Torque wheel lug nuts to the manufacturer’s specifications (usually 100-150 lb-ft).
