Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety glasses, gloves.
Park the vehicle on a level surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Disconnect the battery to ensure safety while working on the braking system.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts of the front wheel(s).
Jack up the vehicle 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

Sub-steps:
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Inspect the brake pads for thickness; replace if they are worn down to less than 3mm.
- If replacing, remove the old pads and install new pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Replace Brake Rotors

Sub-steps:
- Check the rotors for grooves, scoring, or warping. If the surface is damaged or if the rotor thickness is below specifications, replace the rotors.
- Remove the rotor by taking off any retaining screws and sliding it off the hub.
- Install new rotors, ensuring they are clean and properly aligned.

5. Reassemble Components

Sub-steps:
- Reinstall the caliper over the new brake pads and torque the caliper bolts to the manufacturer's specifications.
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and then torque the lug nuts to the specified value.
