Solution

1. Preparation

Gather tools and parts.
Ensure vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to ensure safety during repairs.

2. Remove Wheel

Using a socket set, loosen wheel lug nuts.
Lift the vehicle with a jack and secure it on jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors (if necessary)

Check Rotors: Measure rotor thickness with a micrometer. If below minimum specifications or warped, proceed to replace.
Remove Caliper: Use a socket set to unbolt the brake caliper and hang it with a wire to avoid straining the brake line.
Remove Rotor: Unbolt the rotor from the hub (if applicable) and slide it off.
Install New Rotor: Place the new rotor onto the hub and secure it with bolts as per manufacturer specifications (usually 20-25 ft-lbs).

4. Inspect and Replace Brake Pads (if necessary)

Check Pads: Inspect brake pads for wear. If worn below the minimum thickness, replace as needed.
Remove Old Pads: Remove the retaining clips and slide out the old pads from the caliper bracket.
Install New Pads: Slide new pads into place, ensuring proper alignment with the caliper.

5. Reassemble Components

Reattach the brake caliper to the bracket and torque bolts to manufacturer specifications (usually 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to the specified value (typically 100-120 ft-lbs).

6. Final Check

Reconnect the battery.
Test the brakes by pressing the pedal a few times to ensure proper seating of components.
