Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Raise and Secure the Vehicle

Use a jack to lift the front of the vehicle and secure it on jack stands.
Remove the front wheels using a lug wrench.

3. Inspect and Replace Brake Components

A. Brake Rotor Inspection

Remove the brake caliper by unbolting it from the mounting bracket.
Carefully slide the caliper off the rotor and suspend it using a bungee cord or wire to avoid straining the brake line.
Inspect the rotor surface for warping or grooves. If warped, proceed to replace.
Tools Required: Socket set

B. Brake Pad Inspection

Remove the brake pads from the caliper bracket. Check for uneven wear or insufficient thickness.
Replace with new pads if they are worn down below the manufacturer's recommended thickness.
Tools Required: Brake pad spreader

C. Rotor Replacement

If necessary, remove the brake rotor by unbolting it from the hub assembly.
Install the new rotor, ensuring it is properly aligned and bolted in place to the manufacturer's torque specifications.
Torque Value: Generally around 100-130 ft-lbs (check manufacturer specifications).

4. Reassemble and Test

Reinstall the brake caliper over the new pads and rotor.
Reattach the wheel and tighten the lug nuts in a crisscross pattern to the manufacturer's specifications.
Lower the vehicle back to the ground and reconnect the battery.
