Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Locate the Leak

Sub-step 1: Remove the engine cover if necessary to access brake components.
Sub-step 2: Clean the area around the brake fluid reservoir, master cylinder, and brake lines with a cloth to identify the source of the leak.

3. Replace Damaged Components

Sub-step 1: If the brake lines are damaged, use a wrench to disconnect the affected line from the master cylinder and caliper.
Sub-step 2: Install the new brake line, ensuring it is routed correctly and securely tightened (use a torque wrench to the manufacturer specifications).
Sub-step 3: If the master cylinder is leaking, disconnect the brake lines and unbolt the master cylinder from the brake booster. Install the new master cylinder and reconnect the lines tightly.

4. Refill Brake Fluid

Sub-step 1: Once repairs are made, refill the brake fluid reservoir with the recommended brake fluid type (usually DOT 3 or DOT 4).
Sub-step 2: Bleed the brake system to remove any air trapped in the lines, ensuring proper brake function.

5. Final Checks

Sub-step 1: Inspect all connections to ensure there are no leaks.
Sub-step 2: Reinstall any components removed during the repair and close the hood or engine cover.
