Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Wear appropriate safety gear, including gloves and goggles.

2. Inspect and Replace Brake Fluid

Sub-steps:
- Open the master cylinder reservoir cap.
- If fluid is low, top it up with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
- Close the cap securely.
Tools Required: Brake fluid, funnel.

3. Check and Repair Brake Lines

Sub-steps:
- Inspect brake lines for any signs of wear, corrosion, or leaks.
- If leaks are found, replace the damaged section of the brake line using a line cutter and flaring tool.
- Ensure all connections are secure and leak-free.
Tools Required: Line cutter, flaring tool, wrenches.

4. Bleed Brake System

Sub-steps:
- Begin with the brake furthest from the master cylinder (usually the rear passenger side).
- Attach a clear plastic hose to the bleeder valve on the brake caliper and place the other end in a container.
- Have an assistant pump the brake pedal until firm, then hold it down.
- Open the bleeder valve to release air and fluid, then close it before the assistant releases the pedal.
- Repeat until fluid runs clear without bubbles.
- Move to the next brake in the order: rear driver, front passenger, front driver.
Tools Required: Bleeder kit or clear tubing, container.

5. Inspect and Replace Master Cylinder (if necessary)

Sub-steps:
- Remove the brake fluid reservoir and disconnect brake lines from the master cylinder.
- Unbolt the master cylinder from the brake booster.
- Install the new master cylinder by reversing the removal steps, ensuring proper alignment and torque specifications (typically around 15-20 ft-lbs).
Tools Required: Socket set, torque wrench.
