Solution

1. Preparation

Tools Required: Wrench set, brake fluid, clean rags, jack and jack stands, safety goggles, gloves.
Ensure the vehicle is parked on a flat surface and turn off the engine. Wear safety goggles and gloves to protect against brake fluid.

2. Inspect and Replace Damaged Components

A. Inspect Brake Lines

Use a wrench to disconnect any corroded or damaged brake lines.
Replace with new brake lines that meet OEM specifications.
Tighten connections to the manufacturer’s torque specifications.

B. Check and Replace the Master Cylinder

Disconnect the brake fluid reservoir and remove the master cylinder by unbolting it from the brake booster.
Inspect the master cylinder for any cracks or leaks.
If damaged, replace with a new master cylinder and ensure the new unit is properly bled to remove air.

C. Examine and Replace Brake Calipers

Remove the wheel and inspect the brake caliper for leaks.
If fluid is leaking from the caliper, remove it by unbolting it from the caliper bracket.
Replace with a new caliper and ensure it is bled correctly to eliminate air.

3. Refill and Bleed Brake System

Refill the brake fluid reservoir with the specified brake fluid (DOT 3 or DOT 4).
Begin bleeding the brakes starting from the farthest wheel from the master cylinder to the closest, using a helper or a brake bleeder tool.
