2
Check brake pads for wear and ensure they are properly seated.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety while working on the brake system.

2. Remove Wheel

Loosen the lug nuts using a socket set while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake system.

3. Inspect and Replace Brake Rotors

Inspection: Check the rotors for warping using a runout gauge; if more than 0.002 inches of runout is present, they should be replaced.
Removal: Unbolt the caliper using a socket and slide it off the rotor. Support it with a bungee cord or similar to avoid stress on the brake line.
Rotor Replacement:
- Remove the rotor by unscrewing any retaining screws and sliding it off the wheel hub.
- Clean the hub surface with a wire brush to ensure proper contact.
- Install the new rotor, ensuring it is seated correctly. Reinstall any retaining screws.

4. Replace Brake Pads

Removal: Remove the brake pads from the caliper bracket.
Installation: Apply anti-squeal grease to the back of the new pads. Install the new brake pads into the caliper bracket.
Reattach Caliper: Slide the caliper back over the new pads and secure it with bolts to the specified torque (usually between 25-30 Nm).

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically 100-120 Nm).
Reconnect the battery and perform a brake test in a safe area to ensure everything functions properly.
