Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles during the repair process.

2. Inspect and Repair Brake Lines

Tools Required: Wrench set, brake line flaring tool, brake line cutter.
Inspect all brake lines for leaks or corrosion; replace any damaged lines.
If replacing, cut the old line and flare the ends of the new line for proper fitting.

3. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
If low, top off with the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear hose, catch container.
Start with the wheel farthest from the master cylinder (usually the right rear).
Attach the clear hose to the bleeder valve, submerge the other end in the catch container filled with brake fluid.
Have an assistant pump the brake pedal several times, then hold it down while you open the bleeder valve to release air and fluid.
Close the valve, then have the assistant release the pedal. Repeat until no air bubbles are visible.
Proceed to the next wheel in the sequence: left rear, right front, left front.

5. Test Brake System

After bleeding, check the brake pedal feel; it should feel firm.
Perform a test drive to ensure proper brake function and check for leaks.
