Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen lug nuts with a lug wrench.
Use a jack to elevate the vehicle and place jack stands for safety.
Remove the wheel to access the brake assembly.

3. Inspect Brake Components

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor while supporting it to avoid strain on the brake line.
Check brake pads for thickness; replace if they are less than 3mm.
Inspect the rotor surface for scoring or grooves. Replace if damaged.

4. Replace Brake Pads (if necessary)

Remove old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly seated.
Apply brake grease to the backing of the pads to reduce noise.

5. Reassemble Brake Components

Reinstall the caliper over the new pads and secure with caliper bolts to the specified torque (usually 25-30 ft-lbs).
Reinstall the wheel and tighten the lug nuts in a star pattern to ensure even pressure.
Lower the vehicle and remove jack stands.

6. Final Inspection

Check brake fluid level and top up if necessary.
Pump the brake pedal a few times to ensure proper pad seating and restore brake pressure.
