Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Wheel

Loosen the lug nuts using a lug wrench.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Measure the thickness of the brake pads; replace if below manufacturer specifications (usually 3mm).
Install new brake pads in the caliper bracket, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or warping using a micrometer.
If rotors are below minimum thickness or excessively damaged, remove them from the hub.
Install new rotors, ensuring they are torqued to manufacturer specifications (typically 70-80 ft-lbs).

5. Reassemble Components

Reinstall the caliper over the new brake pads and secure it with the caliper bolts, torquing them to the specified value (usually around 25-30 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value (typically 76-83 ft-lbs).

6. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to seat the brake pads against the rotors.
Check brake fluid level and top off if necessary.
