Summary:

There is a quite a wide range of brake fluid performance parameters affecting the lifetime of a brake fluid while in service in a car. However, in particular a high boiling point stands out as one of the most important product characteristics, in order to provide adequate protection against vapor lock in a car's brake system.Using laboratory experiments and on the road car trials, we have investigated a number of key parameters that affect brake fluid service life. In particular we have compared the boiling performance of DOT 3 versus DOT 4 brake fluid types, id est non-borated versus borated glycol ether based types. The results lead us to the conclusion that DOT 4 compared to DOT 3 brake fluid offers consistently better boiling point performance; id est up to several years DOT 4 offers a considerable better margin against vapor lock.Furthermore, comparing different types of DOT 4 fluids in various car trials, we obtained solid evidence that higher wet boiling point fluids offer the potential to increase the service interval, provided the brake system minimizes moisture ingestion
