Solution

1. Preparation

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

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel completely to access the brake assembly.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Check the thickness of the brake pads; replace if below 3mm.
Brake Rotors:
- Check for any scoring or grooves on the rotor surface.
- Measure rotor thickness; replace if below the manufacturer's specifications.
Calipers:
- Inspect for any signs of sticking or leakage.
- Clean the caliper slides and apply brake grease if needed.

4. Replace Components (if necessary)

Brake Pads:
- If replacement is needed, remove the old brake pads and install new ones, ensuring they are properly seated.
Brake Rotors:
- If replacing, remove the old rotor and install the new rotor, ensuring it is secured and properly torqued.

5. Reassemble Braking System

Reattach the caliper over the new pads/rotor.
Tighten caliper bolts to the manufacturer’s specified torque value.
Reinstall the wheel and hand-tighten the lug nuts.

6. Test the Braking System

Lower the vehicle and tighten lug nuts to the specified torque.
Pump the brake pedal to ensure proper engagement before driving.
