Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Put on safety glasses and gloves for protection.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect the brake pads for wear. If they are worn down (less than 3mm thickness), replace them.
Tools Required: Socket set, torque wrench
Remove the caliper bolts and slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly seated.

4. Inspect and Resurface or Replace Rotors

Check the rotor surface for grooves or uneven wear. If damaged, they may need to be resurfaced or replaced.
If resurfacing, ensure the rotor thickness meets manufacturer specifications.
Tools Required: Brake rotor gauge, possibly a rotor resurfacer
If replacing, remove the caliper bracket, and replace the rotor.

5. Reassemble Braking Components

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

6. Final Inspection

Check brake fluid level and top off if necessary.
Pump the brake pedal to ensure proper pad seating before driving.
