Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is on a flat surface and securely parked.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Loosen the lug nuts using a socket set.
Elevate the vehicle using a jack and secure with jack stands.
Remove the wheel completely to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a wrench.
Carefully lift the caliper off the rotor and support it with a bungee cord (do not hang by the brake line).
Inspect the brake pads for wear; if less than 1/8 inch thick, replace them.
If replacing, remove the old pads and insert new ones, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Check the surface of the rotors; if scored or warped, they need replacement.
Remove the rotor by unscrewing any retaining screws (if present) and sliding it off the hub.
Install new rotors, ensuring they are clean and free of grease.

5. Reassemble Brake Components

Reattach the caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications.
Reinstall the wheel and torque lug nuts.

6. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure proper seating of the pads.
Check brake fluid level and top off if needed.
