Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety goggles and gloves.

2. Raise Vehicle

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

3. Remove Brake Components

Brake Caliper Removal
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it with a bungee cord to avoid straining the brake line.
Brake Pad Removal
- Remove the old brake pads from the caliper bracket.
- Inspect the brake pads for wear; if they are worn down to the indicator, they need replacement.

4. Inspect and Replace Rotors (if necessary)

Check the rotor surface for any scoring or uneven wear.
If damaged, remove the rotor by unscrewing the retaining screws (if equipped) and pulling the rotor off.
Install a new rotor by sliding it onto the hub and securing it with screws.

5. Install New Brake Pads

Apply brake grease to the backs of the new brake pads to reduce noise.
Install the new brake pads into the caliper bracket.

6. Reassemble and Lower Vehicle

Reattach the caliper over the new pads and tighten the mounting bolts to the manufacturer's torque specifications (typically around 25-30 Nm).
Reinstall the wheel and lower the vehicle from the jack stands.

7. Test Brake System

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