Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles for personal protection.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle and secure it on jack stands.
Remove the wheels to access the brake components.

3. Remove Brake Components

Brake Pads:
- Locate the caliper bolts using a socket set and remove them.
- Carefully slide the caliper off the brake rotor without disconnecting the brake line.
- Remove the old brake pads from the caliper bracket.
Brake Rotors:
- If replacing rotors, remove the rotor retaining screws, if equipped.
- Slide the rotor off the hub. If it’s stuck, gently tap it with a rubber mallet.

4. Install New Components

Brake Rotors:
- Clean the new rotor with brake cleaner to remove any protective coating.
- Slide the new rotor onto the hub and secure it with retaining screws.
Brake Pads:
- Install new brake pads into the caliper bracket. Ensure they are properly aligned with the rotor.
- Reinstall the caliper over the new pads and tighten caliper bolts to the manufacturer’s specified torque value (typically around 25-30 Nm).

5. Reassemble and Test

Reinstall the wheels and lower the vehicle back to the ground.
Pump the brake pedal a few times to seat the new pads against the rotors.
Test drive the vehicle at low speeds to ensure proper function and check for any abnormal noises.
