Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and wear safety glasses.

2. Remove Wheel

Loosen lug nuts slightly while the wheel is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the rotor, taking care not to strain the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper piston and compress it if replacing pads.
Install new brake pads, ensuring they are properly seated in the bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check rotor thickness with a micrometer; if below specifications, replace.
Remove the caliper bracket if necessary, then remove the rotor.
Clean the rotor hub surface before installing the new rotor.
Install the new rotor and torque it to manufacturer specifications.

5. Reassemble and Test

Reattach the caliper to the bracket and torque bolts to specifications.
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque the lug nuts in a star pattern to manufacturer specifications.
