4. Maintenance

Regular maintenance of your vehicle's braking system is crucial for safety and performance. Brake fluid should be checked periodically for level and condition. Over time, brake fluid can absorb moisture, which lowers its boiling point and can lead to reduced braking efficiency.

Recommended Maintenance Practices:

• Check brake fluid level regularly, ensuring it is between the MIN and MAX marks on the reservoir.
• Replace brake fluid according to your BMW vehicle's manufacturer-recommended service intervals, typically every two years, regardless of mileage.
• Use only new, sealed brake fluid from an unopened container to prevent contamination.

5. Troubleshooting

While brake fluid itself does not typically "malfunction," issues related to its level or quality can indicate problems within the braking system.

Common Issues and Solutions:

• Low Brake Fluid Level: If the brake fluid level is consistently low, it may indicate a leak in the braking system or worn brake pads. Inspect the system for leaks and check brake pad wear. Consult a qualified technician immediately.
• Contaminated Brake Fluid: If the brake fluid appears dark, cloudy, or contains particles, it may be contaminated or old. This can lead to brake fade and reduced performance. The system should be flushed and refilled with new fluid by a professional.
• Spongy Brake Pedal: A spongy or soft brake pedal can be a sign of air in the brake lines or degraded brake fluid. Bleeding the brake system and/or replacing the fluid may resolve this. Seek professional assistance.

Always address braking system issues promptly. Do not attempt repairs if you are not qualified.

Used brake fluid is a hazardous waste and must be disposed of properly according to local environmental regulations. Do not pour used brake fluid down drains or dispose of it with household waste.
