Remove Brake Caliper:
- Unbolt caliper using the appropriate socket.
- Carefully slide caliper off the rotor, ensuring the brake line is not strained.
Replace Brake Pads:
- Remove old pads from the caliper bracket.
- Install new brake pads ensuring they are correctly positioned.
Reattach Caliper:
- Slide the caliper back over the new pads.
- Torque caliper bolts to manufacturer specifications.

5. Inspect and Replace Brake Rotors (if necessary)

Remove Rotors:
