Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner, jack and jack stands.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel using a socket set.
Inspect the brake rotors for warping (check for grooves or uneven surfaces).
If warped, remove the brake caliper by unscrewing the caliper bolts.
Slide off the caliper and hang it using a bungee cord (do not let it dangle on the brake line).
Remove the rotor by unscrewing the rotor screws (if applicable) and sliding it off the hub.
Install new rotors, ensuring they are clean and free of grease.
Reattach the caliper and torque the bolts to manufacturer specifications.

3. Inspect and Replace Brake Pads

If brake pads are worn or uneven, replace them.
Remove the old pads by sliding them out of the caliper bracket.
Install new brake pads, ensuring they are properly seated.
Apply brake grease to the backing of the pads to reduce noise.

4. Check Wheel Alignment and Suspension

Inspect control arms, tie rods, and bushings for wear or damage.
If any components are worn, replace them as necessary.
Have the vehicle's alignment checked and adjusted by a professional if needed.
