Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather necessary tools: jack, jack stands, lug wrench, brake cleaner, and safety goggles.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and support it with jack stands.
Remove the wheel completely to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts with a socket wrench.
Slide the caliper off the rotor and support it with a strap to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated correctly.

4. Inspect and Replace Rotors (if necessary)

Check the rotor for damage or excessive wear.
If replacement is needed, remove the caliper bracket by unbolting it.
Slide the rotor off the hub; clean the hub surface if necessary.
Install the new rotor, ensuring it is flush against the hub.

5. Reassemble Components

Reattach the caliper bracket and caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications.
Reinstall the wheel and torque the lug nuts in a crisscross pattern.

6. Final Checks

Pump the brake pedal to seat the new pads.
Check brake fluid level and top off if necessary.
Lower the vehicle and perform a test drive to ensure proper function.
