Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Wear safety goggles and gloves.

2. Address Low Brake Fluid

Sub-step 1: If the brake fluid is low, top it up with the appropriate DOT brake fluid (typically DOT 3 or DOT 4).
Sub-step 2: Check for leaks again after adding fluid.

3. Repair or Replace Leaking Components

Sub-step 1: If leaks are found in brake lines, use a line wrench to disconnect the damaged section.
Sub-step 2: Replace the damaged brake line or hose with a new one, ensuring proper routing.
Sub-step 3: If leaks are from the brake caliper or wheel cylinder, remove the affected component using a socket set and replace it with a new one.

4. Master Cylinder Inspection/Replacement

Sub-step 1: If the master cylinder is faulty, remove it by unbolting it from the brake booster.
Sub-step 2: Disconnect the brake lines and electrical connectors (if applicable).
Sub-step 3: Install the new master cylinder and reconnect all lines and connections, ensuring no air is trapped in the lines.

5. Bleed the Brake System

Sub-step 1: Begin at the wheel farthest from the master cylinder (usually the rear passenger side).
Sub-step 2: Use a brake bleeder kit to bleed the brakes, ensuring all air is removed from the lines.
Sub-step 3: Repeat for the other wheels in the correct order (rear passenger, rear driver, front passenger, front driver).
