Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Identify Leak Source

Sub-steps:
1. Remove the wheel where the leak is suspected, using a lug wrench.
2. Clean the suspected areas of the brake system to identify the source of the leak clearly.
3. Use a flashlight to inspect the brake lines, calipers, and hoses for any visible cracks or fluid accumulation.

3. Repair or Replace Affected Components

Sub-steps:
1. If the brake lines are damaged, use a brake line wrench to disconnect the affected line and replace it with a new line (ensure proper length and diameter).
2. For faulty calipers, use a socket set to remove the caliper bolts, detach the caliper, and replace it with a new unit. Torque bolts to manufacturer specifications (usually around 20-30 ft-lbs).
3. If the master cylinder is leaking, disconnect brake lines and remove the master cylinder from the brake booster. Replace it with a new cylinder and ensure proper sealing.

4. Bleed the Braking System

Sub-steps:
1. Refill the brake fluid reservoir with the specified brake fluid (DOT 3 or DOT 4 as per manufacturer).
2. Begin bleeding the brakes starting from the furthest wheel from the master cylinder and move towards the closest wheel (typically: right rear, left rear, right front, left front).
3. Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve on each caliper.
