Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and securely raise the vehicle using jack stands.
Wear safety glasses and gloves for protection.

2. Inspect and Replace Brake Pads and Rotors

Inspect Brake Pads: Remove the wheel to access the brake assembly. Check the thickness of the brake pads (should be at least 3mm).
Replace Brake Pads: If worn, remove the caliper bolts using a socket set, then slide the caliper off the rotor. Remove old pads and install new pads, ensuring they are properly seated.
Check and Replace Rotors: Inspect the rotors for grooves or warping. If damaged, remove the rotor by unbolting it from the hub. Install new rotors, ensuring they are torqued to manufacturer specifications (typically around 80-100 ft-lbs).

3. Inspect and Tighten Suspension Components

Check Suspension Parts: Visually inspect control arms, struts, and bushings for wear or damage.
Tighten Loose Components: If any parts are loose, use a torque wrench to tighten them to the manufacturer's specifications.

4. Check Brake Calipers

Inspect Calipers: Ensure calipers are functioning properly and not seized.
Replace Calipers if Needed: If calipers are sticking, replace them by unbolting from the bracket and installing new calipers, ensuring proper brake line connections.

5. Final Checks

Refill Brake Fluid: If brake fluid was lost during repairs, refill with the appropriate type (DOT 3 or DOT 4).
Bleed Brake System: If any air was introduced into the brake lines, bleed the system to ensure proper brake function.
