Solution

1. Preparation

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

2. Inspect and Replace Brake Pads

Remove the brake caliper by unscrewing the caliper bolts with a socket wrench.
- Torque Specification: Reinstall bolts to manufacturer’s specifications (consult service manual).
Slide out the old brake pads and inspect for wear (less than 3mm thickness indicates replacement).
Clean the caliper bracket and sliding pins with brake cleaner.
Install new brake pads, ensuring proper orientation and fit.

3. Inspect and Resurface or Replace Rotors

Remove the brake rotor by unscrewing the retaining screws (if applicable).
Inspect the rotor surface for grooves or scoring.
If the rotors are within specification, resurface them. If they are too worn, replace with new rotors.
- Torque Specification: Reinstall rotor screws to manufacturer’s specifications.

4. Reassemble Braking Components

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

5. Final Checks

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