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 gear, including gloves and safety glasses.

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Components

Brake Rotors

Sub-steps:
1. Remove the caliper bolts with a socket set and lift the caliper off the rotor.
2. Hang the caliper using a bungee cord to avoid stress on the brake line.
3. Remove the brake rotor by unscrewing any retaining screws if present.
4. Measure the rotor with a micrometer to check for warpage (should be within specifications, usually under 0.005 inches).
5. If warped, replace with new rotors.

Brake Pads

Sub-steps:
1. Inspect the brake pads for thickness; replace if less than 3mm.
2. Remove the old pads and install new pads, ensuring proper orientation and alignment.
3. Apply brake grease on the backing of the pads to reduce noise.

4. Reassemble and Lower the Vehicle

Reattach the brake caliper over the new pads and rotors, tightening the caliper bolts to the manufacturer’s torque specifications (typically around 25-30 Nm).
Reinstall the wheels and lower the vehicle back to the ground.

5. Test Drive

After the repair, perform a test drive to ensure brakes function properly and no vibrations are present.
