Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Tools Required: Socket set, brake bleeder kit, OBD-II scanner, safety goggles, gloves.
Safety Warnings: Always wear safety goggles and gloves when handling brake fluid as it is corrosive.

2. Check and Refill Brake Fluid

Open the hood and locate the brake master cylinder reservoir.
Check the fluid level; if it is below the minimum mark, proceed to refill.
Use the manufacturer-recommended brake fluid (typically DOT 3 or DOT 4).
Clean any dirt from the reservoir cap before removing it to avoid contamination.

3. Inspect and Bleed Brake Lines

After ensuring the fluid level is adequate, inspect each brake line for leaks or damage.
If air is suspected in the brake lines, use a brake bleeder kit:
- Start with the wheel farthest from the master cylinder (usually the right rear).
- Attach the bleeder hose to the brake caliper bleeder valve, and have an assistant press the brake pedal.
- Open the bleeder valve slowly to allow brake fluid and air to escape. Close the valve before the assistant releases the brake pedal.
- Repeat until no air bubbles appear in the fluid.
- Move to the next wheel and repeat the process in the correct order (right rear, left rear, right front, left front).

4. Inspect Brake Components

Remove the wheel and inspect brake pads for excessive wear.
Ensure pads are properly seated and have sufficient material left (minimum 3mm thickness).
Check calipers for proper operation and ensure they move freely.

5. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Test the brake pedal feel; it should no longer feel soft.
If it still feels spongy, further investigation into the ABS system may be necessary.
