Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Inspect and Replace Brake Components

Inspect Brake Rotors

Remove the wheel using a socket set.
Visually inspect the rotors for warping or grooves.
Use a dial indicator to measure runout; it should be within manufacturer specifications (typically less than 0.002 inches).

Replace Brake Pads

Remove caliper bolts using a socket set.
Carefully lift the caliper off the rotor and secure it (do not let it hang by the brake line).
Remove old brake pads and check for uneven wear.
Install new brake pads, ensuring they are seated correctly.

Replace or Resurface Rotors

If rotors are warped beyond tolerance, replace them with new ones or have them resurfaced.
Follow manufacturer specifications for torque settings when reinstalling rotors.

3. Inspect Suspension Components

Check for any signs of wear or damage in suspension components.
Replace any worn or damaged parts (control arms, bushings, struts) as necessary.

4. Reassemble and Test

Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.
Reconnect the battery.
Test the brakes in a safe environment to ensure the issue is resolved.
