Simple Truth: When to Replace Brake Fluid

Brake fluid is one of those maintenance items that’s easy for Kelowna drivers to overlook.  For one, it doesn’t have to be replaced that often and when it should it’s often not as well-defined as, say, an oil change.  Brake fluid does become contaminated over time, however, and needs to be replaced before damage is done.

Two of the most common contaminants in brake fluid are water and copper.

Brake fluid is hygroscopic, meaning it attracts moisture.  Over several years it can actually build up a fair amount of water.  Too much water in the brake fluid causes a couple of problems.  First, water can react with brake system components and cause rust corrosion which can lead to leaks.  Second, the water could boil.  By the calipers, brake components can get very hot.  Water in the brake lines in that area can turn to steam which doesn’t compress like brake fluid.

It may seem strange to talk about testing for copper in brake fluid, but what Kelowna drivers may not know is that the steel brake lines (hoses), are actually lined with copper.  The copper protects the brake lines from rusting due to the water that collects in the fluid. 

As brake fluid heats and cools, some of the copper lining ionizes and flows around in the fluid.  This can lead to two potential problems.  First, if enough copper comes off the lining, the steel in the lines is unprotected and can corrode.  Second, the copper ions floating around are “looking” for some metal to bond with.  This leads to copper plating in some sensitive areas like the anti-lock brake module which can hurt its function.
