craigyb Posted October 7, 2010 Share Posted October 7, 2010 I bought one of the brake fluid testers, which tests for water levels in the fluid. My intention is to use this technique, and only replace the brake fluid when it's water level gets too high. Should there be any other considerations as to when to repalce the brake fluid?

Stationary M25 Traveller Posted October 7, 2010 Share Posted October 7, 2010 The water sinks to the lowest point of the system, so not sure what a test of the fluid in the master cylinder would tell you ? Should replace brake fluid every couple of years ideally, to remove any chance of water, which will corrode the cylinders in the calipers. Link to comment Share on other sites More sharing options...
rj Posted October 7, 2010 Share Posted October 7, 2010 Why not just change the brake fluid every year. It's not as if it costs a fortune. Nor is it very difficult to do! Link to comment Share on other sites More sharing options...

craigyb Posted October 8, 2010 Author Share Posted October 8, 2010 So I wondered whether there are any other factors in the lifetime of brake fluid, other than water contamination? Cheers Craig Link to comment Share on other sites More sharing options...

Rich N Posted October 8, 2010 Share Posted October 8, 2010 Boiling the brake fluid will introduce gas and lead to springy pedal. And probably change other characteristics of the fluid, which is why we change it here and there. You can tell if it needed changing, after you've changed it, if it's suddenly better. 😬 Link to comment Share on other sites More sharing options...
Ged Posted October 8, 2010 Share Posted October 8, 2010 I have read, but stand to be corrected, that the "race spec" brake fluids do not contain corrosion inhibitors that the standard types do, therefore require more frequent changes. Link to comment Share on other sites More sharing options...
Dickie Normuss Posted October 8, 2010 Share Posted October 8, 2010 It's cheap and providing you don't screw it up (guess how I know) it's easy to do. I wouldn't worry about testing it, just change it every couple of years. VX HPC - Loud and proud here Adding power makes you faster on the straights.

Stijn LUYCK 1 Posted October 8, 2010 Share Posted October 8, 2010 Silly question from someone who is bored at work ... if you would heat up break fluid in an open container to let's say 150C would that not remove the water content and allow it to be "good" again (beside the other properties that might have changed)? Told you I was bored .... Edited by - Stijn LUYCK on 8 Oct 2010 16:31:52 Link to comment Share on other sites More sharing options...

geko Posted October 9, 2010 Share Posted October 9, 2010 Hi, the azeotrope is not a bug it´s a feature. It prevents "free" water in the brake (fluid) system and therefore corrosion.
