3
Measure rotor thickness to ensure they are within manufacturer's specifications.
4
Examine calipers for proper operation and sticking.

Solution

1. Preparation

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

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper mounting bolts using a socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord or similar to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated properly.

4. Resurface or Replace Rotors

If the rotors are warped, choose to either resurface them with a brake lathe or replace them if they are beyond specification.
To resurface, mount the rotor on the lathe and follow the manufacturer's guidelines for thickness.
If replacing, remove the rotor by unscrewing the rotor screws and sliding it off the hub.

5. Reassemble Brake Components

Reinstall the caliper over the new pads and rotor.
Tighten the caliper mounting bolts to the manufacturer’s torque specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Finalize

Lower the vehicle and fully tighten the lug nuts in a star pattern to the manufacturer’s specifications (usually around 100-150 ft-lbs).
Reconnect the battery.
