Why is a Brake Flush Service Necessary?
A brake flush service is not some conspiracy to put your car mechanic’s kids through college. It really is necessary for the health and safety of your car. Most car manufacturers recommend flushing the brakes every two years or 30,000 miles. Any moisture that gets into the braking system is absorbed by the brake fluid, which is held in the suspension. Over time and mileage, the brake fluid reaches the point where it no longer can hold the moisture. This can not only rust your brake parts from the inside, but it can actually reach a dangerous boiling point under strenuous braking conditions.
Anti-locking brakes especially can be susceptible to moisture, not to mention expensive to replace. Consider your brake flush an investment against outright replacing the brakes before necessary.
How to Tell If Your Brakes Need Flushed
At the very least, you should have the brake fluid inspected by a mechanic you trust. Fluid in good condition should be clear or translucent. Rust colored fluid is indication moisture has gotten into the line, and you should get a flush. If the fluid is black or burned, your brakes have a more serious problem your mechanic will need to address.
Most European cars, including Porsche, BMW, Jaguars and other imports, should have their brakes flushed every two years or so, depending on mileage and the amount of braking you do.
