Solution

1. Preparation

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

2. Identify the Leak Source

Sub-step 1: Start with the brake fluid reservoir; remove the cap and check fluid levels.
Sub-step 2: If levels are low, inspect the master cylinder for leaks by looking for wetness or residue around it.
Sub-step 3: Next, trace the brake lines from the master cylinder to each wheel, checking for cracks or signs of leakage.

3. Repair or Replace Components

Sub-step 1: If a damaged brake line is found, cut out the damaged section and replace it with a new line, ensuring proper fitting.
Sub-step 2: For leaking brake calipers, disassemble the caliper, replace the seals, and reassemble; if the caliper is severely damaged, replace it entirely.
Sub-step 3: If the master cylinder is leaking, remove it from the vehicle and replace it with a new unit, ensuring to properly bench bleed the new master before installation.

4. Refill and Bleed Brake System

Sub-step 1: After repairs, refill the brake fluid reservoir with the correct type of brake fluid (DOT 3 or DOT 4 as specified).
Sub-step 2: Bleed the brake lines to remove any air trapped in the system, starting from the wheel farthest from the master cylinder to the closest.

5. Final Inspection

Sub-step 1: Inspect all connections and repaired areas for leaks after refilling the system.
Sub-step 2: Ensure the brake pedal feels firm and requires normal pressure during testing.
