Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to ensure safety.

2. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, socket set, brake rotor removal tool, brake cleaner.
Remove the wheel to access the brake assembly.
Inspect the rotor for warping or scoring; if warped beyond specification, proceed to replace.
Remove caliper bolts and slide the caliper off the rotor, supporting it with a bungee cord to avoid stress on the brake line.
Remove the old rotor; clean the hub surface with brake cleaner.
Install the new rotor, ensuring it is seated properly.
Reattach the brake caliper and torque bolts to the manufacturer's specifications.

3. Inspect and Replace Brake Pads

Inspect brake pads for thickness; if below 3mm, replace them.
Remove the caliper and old pads, noting the orientation.
Install new brake pads, ensuring they are properly aligned.
Reassemble the caliper and torque bolts to specification.

4. Check Suspension Components

Inspect control arms, tie rods, and bushings for wear or damage.
Replace any defective components as necessary.

5. Wheel Alignment and Balance

After completing brake repairs, take the vehicle to a professional for alignment and wheel balance to ensure proper handling.
