Diagnostic Steps

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely raised with jack stands.
Disconnect the battery for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Remove Brake Caliper

Locate the caliper bolts (usually two) and remove them using a socket set.
Carefully slide the caliper off the rotor. Support it with a bungee cord or hang it to avoid straining the brake line.

4. Remove Brake Rotor

If applicable, remove any retaining screws holding the rotor in place.
Slide the rotor off the hub. If it is stuck, use a rubber mallet to gently tap it free.

5. Inspect and Clean

Inspect the hub surface for rust or debris. Clean the surface with a wire brush.
Check the new rotor for any protective coating and remove it if necessary.

6. Install New Rotor

Position the new rotor onto the hub.
If removed, re-install any retaining screws.

7. Reinstall Brake Caliper

Slide the caliper back onto the rotor and align it with the mounting holes.
Tighten the caliper bolts to the manufacturer's specified torque (typically around 25-35 Nm).

8. Replace Wheel

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern to ensure even tightening.

9. Final Checks

Reconnect the battery and pump the brake pedal several times to ensure proper caliper positioning.
Check for any leaks around the brake caliper.
