Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, micrometer, brake cleaner, and safety glasses.
Steps:
1. Park the vehicle on a level surface and engage the parking brake.
2. Gather all necessary tools and safety equipment.

2. Lift the Vehicle

Steps:
1. Loosen the lug nuts on the front wheels slightly without removing them.
2. Use a jack to lift the front of the vehicle and secure it with jack stands.
3. Remove the lug nuts and take off the front wheels.

3. Inspect Brake Components

Steps:
1. Visually inspect the brake rotors for signs of warping or uneven wear.
2. Use a micrometer to measure rotor thickness; check against manufacturer specifications.
3. Examine brake pads for thickness; replace if less than 3mm.
4. Inspect brake calipers for any signs of sticking or uneven wear.

4. Replace or Resurface Rotors

Steps:
1. If rotors are warped, either replace them or have them resurfaced by a professional.
2. If replacing, ensure rotors are matched to the vehicle specifications.
3. Clean the new or resurfaced rotors with brake cleaner to remove any protective coating.

5. Replace Brake Pads

Steps:
1. Remove the caliper bolts and lift the caliper off the rotor.
2. Remove the old brake pads and insert new pads ensuring they are properly seated.
3. Reinstall the caliper and secure the bolts to manufacturer specifications using the torque wrench.

6. Reassemble and Test

Steps:
1. Reinstall the wheels and hand-tighten the lug nuts.
