Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface with the engine off.
Wear safety gloves and eyewear.

2. Check Fluid Level

Locate the brake fluid reservoir under the hood.
Clean around the reservoir cap to prevent debris from entering.
Open the cap and visually inspect the fluid level against the minimum and maximum marks.
- Note: If the level is below the minimum mark, top off with the recommended brake fluid type.

3. Inspect for Leaks

Visually inspect the brake lines, calipers, and connections for any signs of fluid leakage.
If leaks are found, mark the locations for repair.

4. Replace Brake Fluid (if necessary)

If fluid is contaminated or below the minimum level:
- 1. Remove the old brake fluid by using a turkey baster or siphon pump.
- 2. Clean the reservoir and refill with fresh brake fluid as per the specifications (typically DOT 4 or BMW's recommended fluid).
- 3. Bleed the brake system to remove any air. This can be done using a brake bleeder kit or by having an assistant pump the brake pedal while you open and close the bleeder valves on each brake caliper.

5. Final Checks

Recheck the fluid level after bleeding and ensure it is at the correct level.
Replace the reservoir cap securely.
