WHY CHANGE YOUR BRAKE FLUID?

Many experts have long recommend changing the brake fluid every year or two for preventative maintenance. Their rationale is based on the fact that glycol-based brake fluid starts to absorb moisture from the moment it is put in the system. The fluid attracts moisture through microscopic pores in rubber hoses, past seals and exposure to the air. The problem is obviously worse in wet climates where humidity is high.

After only a year of service, the brake fluid in the average vehicle may contain as much as two percent water. After 18 months, the level of contamination can be as high as three percent. And after several years of service, it is not unusual to find brake fluid that contains as much as 7-8% water.



ABOVE TO THE RIGHT IS THE MACHINE WE USE TO CHECK THE BOILING POINT OF YOUR CAR'S BRAKE FLIUD, THUS CHECKING THE WATER CONTENT. IT TAKES A SMALL SAMPLE AND CHECKS THE POINT AT WHICH THE FLIUD BOILS. FROM THIS IT CAN TELL IF IT IS DUE FOR CHANGE, THOUGH MOST CAR MANUFACTURERS RECOMMEND EVERY 2 YEARS.
