Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Pads

Lift Vehicle: Use a jack to raise the vehicle and secure it with jack stands.
Remove Wheels: Use a lug wrench to remove the wheel nuts and take off the wheels.
Remove Calipers: Unbolt the brake caliper from the bracket using a socket set. Gently slide the caliper off the brake rotor.
Inspect Pads: Check the brake pads for wear. If they are less than 3mm thick, replace them.
Install New Pads: Position the new brake pads into the caliper bracket. Ensure they are seated properly.

3. Inspect and Resurface/Replace Rotors

Check Rotor Condition: Inspect the brake rotors for warping or scoring.
Resurface or Replace: If the rotors are within specifications, you can resurface them. If they are too thin or damaged, replace with new rotors.
- Use a rotor gauge to measure thickness.
Reinstall Caliper: Slide the caliper back over the new pads and securely bolt it in place.

4. Bleed Brake System

Locate Bleeder Valve: Find the brake bleeder valve on the caliper.
Attach Hose: Connect a clear hose to the bleeder valve and place the other end in a container.
Open Valve: Have an assistant press the brake pedal while you open the bleeder valve to release air and fluid.
Close Valve: Close the valve before the assistant releases the brake pedal. Repeat until all air is purged from the system.
Check Fluid Level: Ensure the brake fluid reservoir is filled to the recommended level.
