Brake fluid is a vital component of your car’s braking system. If it isn’t flushed regularly, the brake pads can start to wear down and create false stopping power. In most cases, brake fluid flushing is an easy task that you can do yourself.
When to Flush Brake Fluid
Most BMWs come with a bleed screw on the brake fluid reservoir. When the brake pads wear, this screw allows fluid to flow from the reservoir and into the brake pads. Brake fluid should be bled at least every two months, but more often if your brakes feel spongy or if there is persistent noise or vibration when you apply the brakes.
Types of Brake Fluid
Different types of brake fluid are designed for specific vehicles and purposes. Here’s a look at the most common types:
– DOT 4: This type of brake fluid is approved for use in all types of vehicles, including motorcycles and cars. DOT 4 fluid is resistant to corrosion and has a high glycol content, which makes it easy to handle and prevents boil-over.
– DOT 5: This type of brake fluid is specifically designed for use in cars and light trucks. It has a lower glycol content than DOT 4 fluid, which makes it less corrosive and also allows it to dissipate heat more quickly. DOT 5 fluid is also less viscous than other types of brake fluid, so it doesn’t build up on rotors as quickly.
– EBCDIC: This type of brake fluid is specifically designed for use in European cars. The acronym stands for Euro Brake Clearance Device Injection Concentrate. EBCDIC brake fluid is resistant to corrosion and contains a higher proportion of glycol than other types of brake fluid.
When to Change the Brake Fluid
Brake fluid should be changed every 7,500 miles or every 3 months, whichever comes first.
How Often to Flush Brake Fluid
The brake fluid in your BMW should be flushed every 6 months or 12,000 miles, whichever comes first.
Brake fluid is a vital part of your braking system and should be regularly checked and replaced if it starts to smell bad or if the fluid appears cloudy or discolored.
Conclusion
If you drive a BMW, it’s important to know how often toflush your brake fluid. Brake fluid is a vital part of your car’s braking system and should be replaced every two years or 25,000 miles. BMW recommends flushing the brake fluid when the level falls below the “low” warning mark on your instrument panel, or every time the brakes are applied.
