Solution

1. Preparation

Tools Required: Jack, jack stands, wrench set, brake fluid, brake bleeder kit, socket set, screwdriver, safety goggles, gloves.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery if necessary to avoid any electrical issues.

2. Inspect and Repair Leaks

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Use a wrench to check all brake line connections for tightness and signs of leaks.
3. Replace any damaged brake lines or fittings with new components.

3. Replace the Master Cylinder (if necessary)

Sub-steps:
1. Locate the master cylinder on the driver's side of the engine bay.
2. Disconnect the brake lines from the master cylinder using a line wrench to prevent stripping.
3. Unbolt the master cylinder from the brake booster and remove it.
4. Install the new master cylinder and torque the bolts to the manufacturer's specifications (typically around 14-18 lb-ft).
5. Reconnect the brake lines and ensure they are secure.

4. Bleed the Brake System

Sub-steps:
1. Fill the master cylinder reservoir with fresh brake fluid.
2. Start bleeding the brakes from the furthest wheel (usually the passenger rear) to the nearest (driver front).
3. Have an assistant pump the brake pedal while you open and close the bleeder valve on the caliper.
4. Repeat the process until no air bubbles are visible in the fluid.
5. Ensure the brake fluid level in the master cylinder remains above the minimum mark during bleeding.
