Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety glasses, gloves.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues during the repair if necessary.

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 completely and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor; support it with a bungee cord to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the brake pads for uneven wear; replace if worn down to the metal.
5. Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for grooves or warping.
2. If damaged, remove the rotor by unscrewing the retaining screws.
3. Install a new rotor, ensuring it is properly aligned and secured.

5. Reassemble and Secure Components

Reattach the caliper to the bracket and tighten the caliper bolts to manufacturer specifications (typically around 25-35 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and wrench down the lug nuts to the specified torque (usually 75-85 lb-ft).
