Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Inspect Brake Fluid

Sub-steps:
1. Open the hood and locate the master cylinder.
2. Check the brake fluid level; it should be between the "MIN" and "MAX" marks.
3. If low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Tools Required: Brake fluid, funnel.

3. Inspect for Leaks

Sub-steps:
1. Visually inspect brake lines for cracks, corrosion, or damage.
2. Check around calipers for fluid leakage.
3. If leaks are found, replace damaged lines or calipers as needed.
Tools Required: Wrench set, brake line replacement kit.

4. Bleed the Brake System

Sub-steps:
1. Start at the wheel farthest from the master cylinder (usually the rear passenger side).
2. Attach a clear hose to the bleeder valve on the brake caliper.
3. Have an assistant pump the brake pedal and hold it down.
4. Open the bleeder valve to release air and fluid, then close it before the pedal is released.
5. Repeat until no air bubbles are observed in the fluid.
6. Move to the next wheel and repeat the process in order.
Tools Required: Bleeding kit, clear tubing.

5. Replace Worn Components

Sub-steps:
1. If brake pads or rotors are worn, jack up the vehicle and remove the wheel.
2. Remove the caliper and bracket using the appropriate socket.
3. Replace the brake pads and/or rotors as needed.
4. Reassemble the caliper and wheel.
Tools Required: Jack and jack stands, socket set, torque wrench.
