Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts on the wheel you will be working on.
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.
Tools Required: Jack, jack stands, lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Locate the brake caliper and remove the bolts securing it.
2. Carefully slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any damage or sticking.
5. If necessary, replace with new brake pads, ensuring they are the correct type for your model.
Tools Required: Socket set, ratchet, bungee cord.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for grooves or warping; if damaged, remove the rotor.
2. To remove, unscrew the retaining screws (if equipped) and slide off the rotor.
3. Install new rotors, ensuring they are clean and free from oil.
Tools Required: Socket set, rotor puller (if necessary).

5. Reassemble Brake Components

Sub-steps:
1. Reattach the caliper over the new pads and rotor.
2. Tighten caliper bolts to manufacturer specifications (usually around 25-30 ft-lbs).
3. Reinstall the wheel and hand-tighten the lug nuts.
Tools Required: Torque wrench.

6. Lower Vehicle and Test Brakes

Sub-steps:
1. Lower the vehicle back to the ground.
2. Tighten the lug nuts to the specified torque (typically 76-100 ft-lbs).
3. Pump the brake pedal a few times to seat the pads against the rotor.
Safety Warnings: Ensure the vehicle is securely supported before working underneath.
