Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery (if working on the brake system) to ensure safety.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel using a socket set.
2. Remove the caliper by unbolting it and securing it with a hanger (do not let it hang by the brake line).
3. Inspect the rotor for warping by using a dial indicator or visually checking for grooves.
4. If warped or damaged, remove the rotor by unscrewing the retaining screws.
5. Install the new rotor, ensuring it is properly seated.
6. Reattach the caliper and wheel, tightening all bolts to manufacturer specifications.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Check the thickness of the brake pads; replace if less than 3mm.
2. Remove the caliper to access the brake pads.
3. Slide out the old brake pads and clean the caliper bracket.
4. Insert new pads, ensuring they are correctly oriented.
5. Reinstall the caliper over the new pads and torque the bolts to specifications.

4. Wheel Alignment and Balancing

Sub-steps:
1. Inspect the front suspension components for any signs of wear.
2. Take the vehicle to a qualified shop for a professional alignment and balance.
3. Ensure tires are rotated and inflated to the recommended pressure.
