The effect of water contamination on brake fluid performance was assessed, partly by measuring fluid temperature under a variety of conditions, but also by analyzing fluid from two samples of cars to obtain information on water contents of fluids in cars on the road. Water contents of one per cent in current brake fluids reduce the vapor lock from around 250C to around 180C. Further increases have progressively less effect. Comparative tests to measure fluid temperatures were carried out on the track using nine different models of car. In addition fluid temperatures in the braking system of one car were measured under a variety of conditions on the road. (Copyright (c) Crown Copyright 1979.)
