Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect the brake pads for thickness; if less than 3mm, replace them.
3. Remove the caliper bolts and carefully slide the caliper off the rotor.
4. Remove the old brake pads and replace with new ones, ensuring they are seated properly.
5. Reattach the caliper and torque bolts to manufacturer's specifications (usually around 25-30 Nm).

3. Inspect and Replace Brake Rotors

Sub-steps:
1. If the rotors are worn or warped (check with a runout gauge), remove the caliper and bracket.
2. Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
3. Install new rotors, ensuring they are clean and free of rust.
4. Reattach the caliper bracket and caliper, torquing the bolts to specifications.

4. Check and Repair Suspension Components

Sub-steps:
1. Inspect control arms, bushings, and struts for any signs of wear or damage.
2. Replace any worn components with OEM or high-quality aftermarket parts.
3. Reassemble any components removed during inspection, ensuring all bolts are torqued to specifications.

5. Wheel Alignment and Balance

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Have the technician perform a four-wheel alignment and balance the tires.
