Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the 12V battery to prevent electrical issues during the repair.

2. Remove Wheel Assembly

Tools Required: Socket set, torque wrench, jack, jack stands
Loosen the lug nuts on the wheel using a socket set.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting it from the bracket using the socket set.
Carefully slide the caliper off the rotor; support it to avoid putting stress on the brake line.
Remove the old brake pads from the caliper bracket. Note their orientation.
Install new brake pads, ensuring they are positioned correctly in the caliper bracket.

4. Inspect and Resurface/Replace Rotors

If rotors are scored, determine if they can be resurfaced using a brake lathe. If not, remove and replace.
To remove, unbolt the rotor from the hub; if stuck, gently tap with a rubber mallet.
Clean the new or resurfaced rotor with brake cleaner to remove any contaminants before installation.
Install the rotor, ensuring it is properly aligned and secure it with bolts to the specified torque.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads and secure it with the bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.

6. Final Steps

Reconnect the 12V battery.
Pump the brake pedal a few times to seat the brake pads.
Check brake fluid level and top off if necessary.
