Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Safety gear: gloves, safety glasses.

2. Remove Wheel

Tools required: Lug wrench, jack, jack stands.
Loosen lug nuts slightly before lifting the vehicle.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel by fully taking off the lug nuts.

3. Inspect and Replace Brake Pads

Check the brake pad thickness; if worn below 3mm, replace.
Remove the caliper bolts using a socket wrench and slide the caliper off the rotor.
Remove old brake pads from the caliper bracket.
Lubricate the caliper bracket with high-temperature brake grease.
Install new brake pads in the caliper bracket.

4. Inspect and Replace Rotors (if necessary)

Check the rotor surface for grooves or scoring. If damaged, replace the rotor.
To remove the rotor, remove any retaining screws and slide it off the hub.
Clean the new rotor with brake cleaner to remove any protective coating.
Install the new rotor and secure it with screws if applicable.

5. Reassemble Braking System

Reattach the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications (typically 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and then fully tighten the lug nuts in a crisscross pattern to the specified torque (usually 76-83 ft-lbs).

6. Final Check

Pump the brake pedal a few times to seat the new pads.
Check the brake fluid level and top off if necessary.
