Brake Fluid

The brake fluid replacement is one of the most frequently forgotten car maintenance services. Many motorists do not even realise that a brake fluid change is an item that should be on their maintenance list and others feel as though their mechanic is trying to take advantage of them or sell an unneeded service when a brake fluid change is recommended. We can assure you that your local mechanic is not trying to take advantage of you. A vehicle’s brake fluid system needs to be replaced periodically in order to help prevent costly brake system repairs.

The primary reason why we must replace brake fluid periodically is because it is a hygroscopic fluid, meaning that it readily absorbs and retains moisture. Even the highest quality brake fluid can only retain so much moisture, however, so it periodically must be flushed from the system and replaced with new fluid.

There are special test strips and other similar items available to help determine when the fluid is in need of changing but a simple method is to assess the colour of the brake fluid in your vehicle’s brake fluid reservoir. Fresh/new brake fluid is clear in colour with a very slight yellow hue. Brake fluid which has served its useful life and is in need of change is deeper amber in colour (or even brown or black in some cases). The use of a flashlight can be helpful in gaining an understanding of brake fluid condition. Use the flashlight to shine through the master cylinder of most late-model vehicles. If the fluid has a heavy amber hue, the fluid is ready to be replaced.

A good general rule of thumb on the frequency for having your modern vehicle’s brake fluid flushed is to have it done every two years, especially on those vehicles equipped with antilock braking systems. Years ago, prior to the advent of antilock brakes, flushing the brake fluid was not as much of a concern. The more intricate fluid circuitry of the hydraulic control units on today’s antilock brake and traction-control equipped vehicles are much more sensitive to moisture and small particulate debris. Additionally, the actuation of these systems during braking or traction controlled events generate heat which further contributes to the breakdown of the brake fluid. With the potential of vehicle safety concerns and brake system repairs that may be a lot more costly in the long run. The money spent on a brake fluid flush every two years is well worth the peace of mind.
