Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, OBD-II scanner, brake fluid tester.
Sub-steps:
- Park the vehicle on a flat surface and engage the parking brake.
- Gather necessary tools and safety equipment (gloves, goggles).
- Ensure the vehicle is cooled down before beginning work.

2. Replace Brake Pads

Tools Required: Socket set, torque wrench, brake caliper tool, C-clamp.
Sub-steps:
1. Loosen the lug nuts and lift the vehicle using a jack.
2. Remove the wheel to access the brake components.
3. Use a brake caliper tool to retract the caliper piston.
4. Remove the caliper bolts and gently slide the caliper off the rotor.
5. Remove the old brake pads and install new ones, ensuring proper orientation.
6. Reinstall the caliper and torque the bolts to manufacturer specifications (usually around 25-35 ft-lbs).
7. Reattach the wheel and lower the vehicle.

3. Flush Brake Fluid

Tools Required: Brake fluid, vacuum bleeder or two-person method for bleeding brakes.
Sub-steps:
1. Remove the brake fluid reservoir cap and inspect fluid condition.
2. Use a vacuum bleeder or have an assistant pump the brake pedal while you open the bleeder valve on each brake caliper, starting from the farthest from the master cylinder (usually right rear, left rear, right front, left front).
3. Continue until clean fluid flows from each bleeder, ensuring no air is trapped in the system.
4. Refill the brake fluid reservoir with new fluid and secure the cap.
