Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during the repair.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket set and take off the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Check for warping using a dial indicator or visually inspect for grooves.
If Warped:
- Remove the caliper by unscrewing the caliper bolts.
- Slide the caliper off and support it without stressing the brake line.
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective grease.
- Install the new rotor on the hub, ensuring it sits flush.
- Reattach retaining screws if applicable.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Apply brake grease to the backing of the new brake pads and install them into the caliper bracket.
Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s specified torque.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and securely tighten the lug nuts to the manufacturer’s torque specification.
Reconnect the battery.
Test the brakes gently to ensure proper function.
