Solution

1. Preparation

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

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully lift the caliper off the rotor without disconnecting the brake line.
- Inspect the brake pads for thickness; replace if below manufacturer specifications.
Replace Brake Pads:
- Remove old brake pads from the caliper bracket.
- Install new brake pads in the bracket ensuring proper alignment.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check the rotors for warping or scoring.
- Measure rotor thickness with a micrometer; replace if below minimum specifications.
Replace Rotors:
- Remove the caliper bracket bolts and take off the caliper bracket.
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- Install the new rotor, ensuring it is seated correctly.

5. Reassemble Components

Reinstall the caliper bracket and torque bolts to manufacturer specifications.
Reinstall the caliper and torque bolts to the specified value.
Put the wheel back on and hand-tighten the lug nuts.

6. Final Steps

Lower the vehicle and torque the lug nuts to manufacturer specifications.
Reconnect the battery.
Test brake performance before normal driving.
