Diagnostic Steps

Solution

1. Preparation

Gather tools: socket set, brake fluid, clean rags, and a brake bleeder kit.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Inspect and Repair Brake System

Brake Fluid Check:
- Remove the master cylinder cap and check the fluid level. If low, add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified).
Identify Leaks:
- Visually inspect all brake components for leaks. Pay special attention to the master cylinder, brake lines, and calipers.
- If leaks are found, replace the affected components (e.g., brake lines or seals).
Bleed the Brakes:
- If air is suspected in the brake lines, use a brake bleeder kit to bleed each wheel. Start with the wheel farthest from the master cylinder (usually the passenger rear) and work to the closest (driver front).
- Ensure the brake fluid reservoir remains full during this process.

3. Inspect Brake Pads and Rotors

Remove the wheel to access the brake assembly.
Check the thickness of the brake pads; replace if they are worn beyond the manufacturer's specifications (usually less than 3mm).
Inspect the rotors for scoring or warping. Replace if necessary.

4. Test the Brake Booster

With the engine off, pump the brake pedal several times. Hold the pedal down and start the engine. The pedal should drop slightly; if it does not, the brake booster may be faulty and should be replaced.
