Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Remove Wheels

Use a lug wrench to remove the wheel bolts and take off the wheel.
Inspect the brake assembly visually for any obvious damage.

3. Replace Brake Rotors (if warped)

Remove the caliper by unscrewing the caliper bolts using a socket set.
- Tools Required: Socket set, torque wrench
- Safety Warning: Support the caliper to avoid stress on the brake line.
Slide the caliper off the rotor and remove the old rotor by unscrewing the retaining screws.
Install the new rotor, ensuring it is aligned correctly and secured with retaining screws.
Reinstall the caliper and torque bolts to the manufacturer’s specifications (typically around 25-30 Nm).

4. Replace Brake Pads (if worn)

Remove the old brake pads from the caliper bracket.
Compress the caliper piston using a brake caliper tool to make room for the new pads.
Insert new brake pads in the caliper bracket, ensuring they are seated properly.
Reinstall the caliper over the new pads.

5. Reassemble and Test

Reattach the wheel and hand-tighten the lug bolts.
Lower the vehicle and torque the wheel bolts to the manufacturer’s specifications (usually around 100-120 Nm).
Reconnect the battery.
