Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted.
Wear safety gloves and goggles.

2. Remove Wheel

Using a lug wrench, loosen the wheel lug nuts slightly before lifting the vehicle.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Remove the brake caliper by unbolting it with a socket wrench.
Carefully hang the caliper using a bungee cord to avoid straining the brake line.
Inspect the brake pads for uneven wear and measure thickness.
Check the brake rotor for any signs of warping or scoring.

4. Address Issues Found

If calipers are sticking, clean and lubricate the caliper slides or replace if damaged.
If pads are uneven, replace both pads on the affected axle.
If rotors are warped, consider resurfacing or replacing them based on thickness specifications.

5. Installation of New Components

Install new or resurfaced rotors if necessary, ensuring they are clean and free of grease.
Reinstall the brake caliper and torque bolts to manufacturer specifications (typically 20-25 ft-lbs).
Install new brake pads, ensuring they are secured and properly positioned.

6. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to manufacturer specifications (typically 100-120 ft-lbs).
Pump the brake pedal to seat the pads before driving.
