BMW Reduced Braking Performance

What Happens if a BMW Owner Avoids a Brake Fluid Flush?

15 Mar, 23

One crucial aspect of vehicle maintenance that is usually overlooked is the brake fluid flush. The brake fluid, which is a hydraulic fluid, transfers force applied to the brake pedal to the brake calipers or wheel cylinders. This applies pressure to the brake pads or shoes, creating friction that slows down or stops the vehicle.

Over time, brake fluid absorbs moisture from the air, and this can lead to a decrease in its effectiveness and performance. This is why manufacturers recommend periodic brake fluid flushes to remove the old, contaminated fluid and replace it with fresh fluid. If a BMW owner avoids brake fluid flushes, several potential issues can arise, which include:

Reduced Braking Performance

Brake fluid absorbs moisture over time, which can lead to a decrease in its boiling point and reduced effectiveness in transferring hydraulic pressure. As a result, the braking performance may be compromised, and the vehicle may take longer to stop, especially during heavy braking or emergency situations. This can increase the risk of accidents and pose a danger to the driver, passengers, and other road users.

Brake System Damage

Moisture in the brake fluid can cause corrosion and damage to various components of the brake system, such as the brake lines, calipers, and master cylinder. Corrosion can weaken brake lines, causing them to develop leaks or bursts, resulting in a loss of brake fluid and reduced braking ability. Damaged calipers and master cylinders may require expensive repairs or replacements, further adding to the maintenance costs.

Brake Fade

Brake fade is a phenomenon that can occur when the brake fluid gets too hot and begins to vaporize, creating gas bubbles in the brake lines. These gas bubbles can compress, reducing the hydraulic pressure and causing a loss of braking power. Brake fade can be particularly dangerous during prolonged or aggressive driving, such as high-speed driving or driving in mountainous terrain, as it can result in a complete loss of braking ability and increase the risk of accidents.

Increased Maintenance Costs

Neglecting brake fluid flushes can lead to increased maintenance costs in the long run. Corroded or damaged brake system components may require costly repairs or replacements. For example, if brake lines develop leaks due to corrosion, they may need to be replaced, which can be labor-intensive and expensive. Prolonged use of contaminated brake fluid can also accelerate wear and tear on brake pads and rotors, leading to more frequent replacements and increased maintenance costs over time.

Voiding of Warranty

Many BMWs come with warranties that cover certain repairs and replacements within a specified period. However, these warranties often require proof of regular maintenance, including brake fluid flushes, to be honored. If a BMW owner neglects recommended maintenance, such as brake fluid flushes, it may void the warranty, resulting in a denial of coverage for brake-related repairs or other issues. This can result in additional out-of-pocket expenses for repairs that would have otherwise been covered under warranty.

Compromised Safety

The most significant risk of avoiding brake fluid flushes in a BMW is compromised safety. BMWs are known for their sporty performance and precise handling, and the braking system plays a crucial role in ensuring the safety of the vehicle and its occupants. Neglecting brake fluid flushes can lead to reduced braking performance, brake system damage, brake fade, and other issues, which can increase the risk of accidents and pose a danger to the driver, passengers, and other road users. Safety should always be a top priority, and regular brake fluid flushes are a crucial aspect of maintaining the optimal performance and safety of a BMW.
