Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and securely place it on jack stands.
Use a lug wrench to remove the wheel nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; if less than 3mm, they need replacement.
Remove Brake Caliper:
- Use a socket set to remove caliper mounting bolts.
- Carefully slide the caliper off the rotor, do not disconnect the brake line.
Replace Brake Pads:
- Remove old brake pads from the caliper bracket.
- Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Measure rotor thickness; if below minimum specification or if warped, replace.
Remove Rotors:
- Remove any retaining screws, if present, and slide the rotor off the hub.
Install New Rotors:
- Clean the new rotor with brake cleaner to remove any protective coating.
- Slide the new rotor onto the hub and secure it.

5. Reassemble Braking Components

Reinstall Caliper:
- Compress the caliper piston using a caliper tool.
- Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications (usually around 20-30 ft-lbs).
Reinstall Wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and then torque the lug nuts to specification (typically 75-100 ft-lbs).

6. Test Brakes

Reconnect the negative battery terminal.
Start the vehicle and pump the brakes to seat the new pads.
Test drive the vehicle to ensure proper brake function and listen for any noises.
