Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Open the hood and locate the master cylinder reservoir.
2. Remove the reservoir cap and check fluid level. If low, add manufacturer-recommended brake fluid (DOT 3 or DOT 4).
3. If the fluid is dirty or contaminated, flush the brake system using fresh brake fluid.

Tools Required:

Brake fluid (DOT 3 or DOT 4)
Funnel

3. Inspect Brake Lines and Components

Sub-steps:
1. Visually inspect brake lines for cracks, corrosion, or leaks.
2. If leaks are found, replace damaged brake lines with OEM parts.
3. Inspect brake calipers for leaks. If leaking, replace calipers.

Tools Required:

Wrench set
Brake line flaring tool (if replacing lines)

4. Bleed the Brake System

Sub-steps:
1. Start at the wheel farthest from the master cylinder (right rear), then proceed to left rear, right front, and finally left front.
2. Use a brake bleeder kit or have an assistant press the brake pedal while you open the bleeder valve on each caliper to allow air and old fluid to escape.
3. Close the valve before releasing the brake pedal and repeat until no air bubbles are visible.

Tools Required:

Brake bleeder kit
Wrench for bleeder screws

5. Test Brake Functionality

Sub-steps:
1. After bleeding, check brake fluid levels again and top off if necessary.
2. Perform a test drive at low speeds to ensure brakes are functioning properly.
3. Look for any warning lights and ensure pedal feel is firm.
