Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Use wheel chocks for added safety.

2. Remove Wheel

Tools Required: Socket set, torque wrench
Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Check brake pad thickness; if below 3 mm, replace.
Remove caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and support it using a bungee cord (do not let it dangle).
Remove old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated properly.

4. Inspect and Resurface or Replace Rotors

Check rotor surface for grooves or damage.
If necessary, resurface rotors using a brake lathe or replace with new rotors.
Clean rotor surface with brake cleaner before installation.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads and torque caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

6. Test Brake Functionality

Start the vehicle and gently pump the brakes to ensure proper pad seating.
Test drive the vehicle to check for noise and braking performance.
