Solution

1. Preparation

Ensure the vehicle is parked on a level surface and engage the parking brake.
Gather necessary tools and parts.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a lug wrench.

3. Remove Brake Caliper

Use a socket set to remove the caliper bolts.
Carefully slide the caliper off the rotor, supporting it with a bungee cord to avoid stress on the brake line.

4. Inspect and Replace Brake Pads

Remove old brake pads from the caliper bracket.
Measure the thickness of the old pads; if less than 3mm, replace them.
Clean the caliper bracket with brake cleaner.
Install new brake pads into the caliper bracket, ensuring they are seated properly.

5. Reassemble Brake Components

Reinstall the brake caliper over the new pads.
Secure caliper bolts to the manufacturer’s torque specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and lower the vehicle.

6. Test Brake Function

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