Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles to protect from brake fluid.

2. Inspect and Identify Source of Leak

Sub-step 1: Visually inspect the brake lines for any signs of damage or leaks.
Sub-step 2: Check the brake calipers and master cylinder for fluid seepage.
Sub-step 3: If a leak is found, mark the area for repair.

3. Replace or Repair Affected Components

Sub-step 1: If a brake line or caliper is leaking, remove the affected component using the socket set.
Sub-step 2: Replace the damaged line or caliper with new parts.
Sub-step 3: Ensure all connections are tight and properly sealed.

4. Refill Brake Fluid

Sub-step 1: Locate the brake fluid reservoir; it is typically found near the back of the engine bay.
Sub-step 2: Remove the reservoir cap and inspect the internal condition.
Sub-step 3: Fill the reservoir with the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Sub-step 4: Replace the reservoir cap securely.

5. Bleed the Brake System

Sub-step 1: Start from the farthest wheel from the master cylinder and work your way closer.
Sub-step 2: Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve on each brake caliper.
Sub-step 3: Ensure there are no air bubbles in the fluid until clean fluid without bubbles comes out.
