Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the braking system.

2. Inspect and Replace Brake Rotors

Remove the Wheel:
- Loosen lug nuts, lift the vehicle with a jack, and secure it on jack stands.
- Remove the wheel to access the brake assembly.
Remove Brake Caliper:
- Unbolt the caliper using a socket set.
- Carefully hang the caliper with a bungee cord to avoid stressing the brake line.
Remove Brake Rotor:
- Remove any retaining screws if present.
- Slide the rotor off the hub; inspect for warping using a dial indicator.
Install New Rotor:
- Clean the hub surface.
- Place the new rotor onto the hub and secure with screws if applicable.

3. Replace Brake Pads

Remove Old Brake Pads:
- With the caliper still suspended, remove the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads (if specified).
- Slide the new pads into the caliper bracket.
Reinstall Caliper:
- Compress the caliper piston using a caliper tool to accommodate the new pads.
- Reattach the caliper and torque bolts to manufacturer's specifications (typically 25-30 Nm).

4. Reassemble Wheel and Test

Reattach the Wheel:
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and torque lug nuts to specifications (usually 100-120 Nm).
Test Drive:
- Carefully test drive the vehicle to ensure braking performance is restored and check for any vibrations.
