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 Refill Brake Fluid

Open the hood and locate the master cylinder.
Check the brake fluid level; if low, top off with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).
Inspect the master cylinder cap for proper sealing.

3. Identify and Repair Leaks

Visually inspect all brake lines, hoses, and connections for leaks.
If leaks are found:
- For brake lines: Replace damaged sections using appropriate brake line tubing and fittings.
- For hoses: Replace any cracked or worn hoses.
- For connections: Tighten or replace any loose fittings.

4. Bleed the Brake System

Start with the wheel farthest from the master cylinder (usually passenger rear).
Use a brake bleeder kit or a helper to pump the brake pedal while opening and closing the bleeder valve on each brake caliper.
Repeat for each wheel (passenger rear, driver rear, passenger front, driver front) until no air bubbles appear in the fluid.

5. Test Brake Operation

Press the brake pedal to ensure it feels firm and does not go to the floor.
Take the vehicle for a test drive at low speeds to ensure proper brake function.
