Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Use wheel chocks to prevent movement.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts with a socket set while the wheel is still on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Socket set, jack, jack stands.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor and support it without stressing the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any damage or sticking.
5. Install new brake pads ensuring they are properly seated.
Tools Required: Socket wrench, brake pad spreader.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If the rotors are scored or warped, remove the caliper bracket and rotor.
2. Clean the hub surface where the rotor sits.
3. Install the new rotor, making sure it is properly aligned.
4. Reattach the caliper bracket over the new rotor.
Tools Required: Socket wrench, rotor puller (if needed).

5. Reassemble and Lower Vehicle

Sub-steps:
1. Reattach the caliper and tighten bolts to manufacturer specifications (typically around 25-35 ft-lbs).
2. Put the wheel back on and hand-tighten the lug nuts.
3. Lower the vehicle from the jack stands.
4. Torque the lug nuts to the specified torque value (generally around 75-85 ft-lbs).
Tools Required: Torque wrench.
