Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Check Pad Thickness: Measure the brake pad thickness; if it’s below 3mm, replace pads.
Remove Caliper: Use a socket set to remove caliper bolts and slide the caliper off the rotor.
Remove Old Pads: Slide out the old brake pads from the caliper bracket.
Install New Pads: Insert new brake pads into the caliper bracket, ensuring they are properly aligned.

4. Inspect and Resurface/Replace Brake Rotors

Check Rotor Condition: Examine the rotor surfaces for grooves or uneven wear.
Resurface or Replace: If the rotors are damaged, either have them resurfaced or replace them with new rotors.
Reinstall Caliper: Position the caliper back over the new pads and secure it with bolts. Torque bolts to manufacturer specifications (typically around 25-30 Nm).

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Pump the brake pedal a few times to ensure the pads make contact with the rotor.
Check the brake fluid level again and top up if necessary.
