Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, brake fluid, torque wrench, brake cleaner, jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Replace Worn Brake Pads

Sub-steps:
1. Lift the Vehicle: Use a jack to raise the vehicle and secure it with jack stands.
2. Remove Wheel: Use a socket set to remove the lug nuts and take off the wheel.
3. Remove Caliper: Unbolt the brake caliper from its bracket; support it without stressing the brake line.
4. Remove Old Pads: Slide the old brake pads out of the caliper bracket.
5. Install New Pads: Insert new brake pads into the caliper bracket, ensuring they are properly seated.
6. Reinstall Caliper: Bolt the caliper back onto the bracket and torque to manufacturer specifications (typically around 25-35 ft-lbs).
7. Reattach Wheel: Place the wheel back on and hand-tighten the lug nuts.

3. Bleed Brake System

Sub-steps:
1. Locate Bleeder Valves: Identify the bleeder valves on each brake caliper.
2. Attach Hose: Connect a clear hose to the bleeder valve and place the other end in a container.
3. Pump Brake Pedal: Have an assistant pump the brake pedal several times and hold it down.
4. Open Bleeder Valve: Open the bleeder valve to release air; close it before the assistant releases the pedal.
5. Repeat: Continue this process until no air bubbles appear in the fluid.
6. Top Off Fluid: Ensure the brake fluid reservoir is filled to the proper level after bleeding.
