Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery to prevent any electrical issues during repair.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake rotor puller.
Remove the front wheel using the socket set.
Unbolt the brake caliper and hang it securely to avoid stress on the brake line.
Remove the brake pads for rotor access.
Use the brake rotor puller to remove the old rotors.
Inspect the new rotors for any protective coating and clean them with brake cleaner.
Install the new rotors, ensuring they are properly seated.

3. Replace Brake Pads

Reinstall the brake pads into the caliper bracket.
Ensure they are aligned correctly and free of debris.
Reattach the brake caliper over the new pads and tighten to manufacturer specifications (typically around 25-35 Nm).

4. Inspect and Replace Suspension Components (if needed)

Tools Required: Ball joint separator, torque wrench, pry bar.
Check for any play in control arms, tie rods, and bushings.
If any components are worn, replace them using the ball joint separator.
Reassemble and torque all components to manufacturer specifications.

5. Wheel Alignment and Tire Check

After repairs, check tire pressure and inspect for uneven wear.
If necessary, perform a wheel alignment to ensure proper handling.
