Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor without stretching the brake line.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to the contact points.
Install new brake pads, ensuring they are oriented correctly.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged, remove them by unscrewing any retaining screws and sliding them off the hub.
Clean the hub surface where the rotor sits.
Install new rotors, ensuring they are properly seated.

5. Reassemble Braking System

Reattach the caliper over the new brake pads and secure it with bolts. Torque to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the recommended specifications.

6. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to seat the brake pads against the rotors.
Check brake fluid level and top off if necessary.
