Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and securely lift the front wheels using a jack and jack stands.

2. Inspect and Replace Brake Rotors

Tools Required: Dial indicator, torque wrench, socket set, brake cleaner, safety goggles, gloves.
Remove the wheel to access the brake assembly.
Use a dial indicator to check the rotor runout; if it exceeds manufacturer specifications, it needs to be replaced.
If replacing, remove the caliper and bracket (ensure to support the caliper with a bungee cord to avoid stress on the brake line).
Remove the rotor and install the new rotor, ensuring it is properly seated.
Reinstall the caliper and bracket, tightening to manufacturer torque specifications.

3. Inspect and Replace Brake Pads

Inspect the brake pads for thickness; if below minimum specifications or unevenly worn, replace them.
Use brake cleaner to clean the caliper and bracket surfaces.
Install new brake pads, ensuring they are correctly positioned and seated.
Reinstall the wheel and torque to manufacturer specifications.

4. Check and Replace Suspension Components

Inspect control arms, bushings, and other suspension parts for wear.
Replace any worn or damaged components.
If necessary, perform a wheel alignment after replacing suspension parts.
