Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, and safety glasses.
Lift the vehicle using a jack and secure it with jack stands. Remove the wheels using a lug wrench.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench and carefully slide the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. Inspect the brake pads for wear; if they are less than 3mm thick, replace them.
4. Install new brake pads into the caliper bracket, ensuring they are seated properly.
5. Reattach the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Remove the caliper and pads as described above.
2. Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
3. Inspect the rotor for scoring or warping; replace if necessary.
4. Install the new rotor, ensuring it is properly seated on the hub.
5. Reinstall the caliper and pads as per the previous steps.

4. Clean and Reassemble

Sub-steps:
1. Use brake cleaner to remove any dust or debris from the rotor and pads.
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to the specified value (typically 95-100 ft-lbs).
