Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect the thickness of the brake pads; if less than 3mm, replace them.
Remove the caliper by unscrewing the caliper bolts (torque specification: typically 20-25 ft-lbs).
Lift the caliper off the rotor and support it to avoid stress on the brake line.
Remove the old brake pads and install new ones, ensuring they are seated properly.

4. Inspect and Resurface/Replace Rotors

Check the rotors for grooves or warping; if they are damaged beyond resurfacing, replace them.
If resurfacing, ensure to follow specifications for rotor thickness.
Clean the rotor surface with brake cleaner before reassembly.

5. Reassemble Components

Reinstall the caliper over the new brake pads.
Tighten caliper bolts to the manufacturer's torque specification.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from jack stands.
Tighten the lug nuts to the specified torque (usually 80-100 ft-lbs).
Reconnect the battery.
Pump the brake pedal a few times to ensure proper pad seating.
