Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electronic brake systems.

2. Inspect and Replace Brake Rotors

Remove the wheel using a socket set.
Unbolt the brake caliper and suspend it safely (do not hang by the brake line).
Remove the brake rotor by unbolting it from the hub.
Check rotor thickness and runout; if warped beyond specifications (usually more than 0.002 inches), replace the rotor with a new one.

3. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Check for uneven wear; if worn unevenly or below the minimum thickness, replace the pads.
Install new brake pads according to manufacturer specifications.

4. Reassemble Components

Reinstall the brake rotor and caliper.
Torque caliper bolts to manufacturer specifications (typically 25-30 ft-lbs).
Reinstall the wheel and torque lug nuts to specifications (usually 76-83 ft-lbs).

5. Final Check

Reconnect the battery.
Check brake fluid level and top off if necessary.
Test the brakes gently in a safe area to ensure proper functionality.
