Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.

2. Inspect and Refill Brake Fluid

Check fluid level: Remove the master cylinder cap and check the brake fluid level. If it is low, refill with DOT 3 or DOT 4 brake fluid as specified in the owner's manual.
Tools Required: Clean rag, funnel.
Safety Warnings: Avoid contact with skin and painted surfaces, as brake fluid is corrosive.

3. Inspect Brake Lines

Visual Inspection: Examine all brake lines for cracks, corrosion, or leaks. Pay special attention to connections and fittings.
Repair or Replace: If leaks are found, replace the damaged brake line or fitting. Use appropriate brake line tools for cutting and flaring.

4. Bleed the Brake System

Procedure:
1. Start at the wheel furthest from the master cylinder (right rear), then work towards the closest (left front).
2. Attach a brake bleeder kit or clear tubing to the bleeder valve on the brake caliper.
3. Have an assistant press the brake pedal while you open the bleeder valve to release air and old fluid. Close the valve before the pedal is released.
4. Repeat until fluid runs clear, ensuring no air bubbles are present.
Tools Required: Brake bleeder kit, socket wrench, catch container.
Safety Warnings: Ensure to keep the master cylinder reservoir topped up to prevent introducing air into the system.

5. Test Brake Booster

Check Functionality: With the engine running, press the brake pedal. It should feel firm and not sink to the floor. If it does, the brake booster may need replacement.
Tools Required: None specific for this test.
