Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Safety warning: Allow the vehicle to cool before working on the brakes.

2. Inspect and Replace Brake Pads

Remove the wheel using a lug wrench.
Check the thickness of the brake pads; if they are below the manufacturer’s minimum specification, replace them.
If replacement is needed, remove the caliper bolts with a socket set, slide the caliper off, and replace the pads.
Reinstall the caliper and torque the caliper bolts to the manufacturer's specifications.

3. Inspect and Resurface/Replace Brake Rotors

Check the rotors for warping using a dial indicator. If warped beyond specifications, replace or resurface the rotors.
To remove rotors, remove the caliper and then the caliper bracket. Use a hammer to gently tap the rotor if it is stuck.
If resurfacing, follow the machine shop instructions. If replacing, install the new rotor, ensuring it is properly seated.

4. Check Suspension Components

Inspect control arms, tie rods, and ball joints for wear or play.
Replace any worn components as necessary to restore alignment and reduce vibrations.

5. Final Assembly and Wheel Reinstallation

Reinstall the caliper bracket and caliper, ensuring all components are torqued to specifications.
Reinstall the wheel and tighten lug nuts in a crisscross pattern to ensure even tightening.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
