Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Disconnect the battery to prevent any electrical issues while working.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, socket set, brake cleaner.
Check the rotor surface for warping using a dial gauge.
If warped or damaged, remove the brake caliper by unfastening the caliper mounting bolts.
- Sub-steps:
  - Suspend the caliper using a wire to avoid stress on the brake line.
  - Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
  - Clean the hub surface before installing a new rotor.
  - Install the new rotor and secure it with retaining screws.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Tools Required: Brake pad spreader tool.
Clean the caliper bracket and apply brake grease to the contact points.
Install new brake pads in the caliper bracket.
Compress the caliper piston using the brake pad spreader tool to fit over the new pads.

5. Reassemble and Test

Reattach the brake caliper over the new brake pads and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and torque the lug nuts in a crisscross pattern.
Lower the vehicle and reconnect the battery.
