Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety glasses, gloves.

2. Remove Wheel

Loosen wheel lug nuts with a lug wrench.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the bolts securing it using a socket set.
Carefully slide the caliper off the rotor.
Inspect the brake pads for thickness; replace if they are less than 3mm.
- Sub-steps:
  - Remove the old brake pads from the caliper bracket.
  - Clean the caliper bracket and apply anti-squeal lubricant to the backing of the new pads.
  - Install the new brake pads and secure them with the caliper.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or excessively worn, remove them by unscrewing the retaining screws (if applicable) and sliding them off the hub.
Install new rotors, ensuring they are clean and free of oil.
Torque Values: Follow manufacturer specifications for the rotor screws.

5. Reassemble and Bleed Brakes

Reattach the brake caliper and tighten the bolts to the manufacturer’s specified torque.
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern.
Lower the vehicle and pump the brake pedal several times to ensure proper brake pad seating.
If brake fluid was lost, bleed the brakes to remove air from the system.
