Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, and safety goggles.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle depending on which brakes are being inspected.
Secure the vehicle on jack stands to ensure stability.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to expose the brake assembly.

4. Inspect Brake Pads

Visually inspect the brake pads for thickness; replace if they are less than 3mm.
Check the rotor for scoring or damage. If damaged, replace or resurface as needed.

5. Replace Brake Pads

Remove Caliper: Unscrew the caliper bolts and slide the caliper off the brake rotor.
Remove Old Pads: Take out the old brake pads from the caliper bracket.
Install New Pads: Insert the new brake pads into the caliper bracket.
Reinstall Caliper: Slide the caliper back over the new pads and secure it with the caliper bolts. Torque bolts to manufacturer specifications (typically around 25-30 Nm).

6. Reassemble

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (usually around 120 Nm).

7. Test Brakes

Pump the brake pedal to seat the new pads.
Conduct a test drive to ensure proper functioning.
