Brake fluid change or upgrade

Postby Gray » Sat Oct 11, 2008 8:40 am

The service manual doesn't give any info on scheduled brake fluid changes but normally DOT 3 brake fluids have a service life of about 1 - 2 years, maybe a bit longer in dry climates. Have any PF owners here had the brake fluid changed or upgraded to a DOT 5.1 or other higher quality ABS compatible fluid. Thanks.

Here's a list of various brake fluid properties;

AP SUPER 600 - Dry Boiling Point=590°F Wet Boiling Point=410°F
CASTROL SRF - DBP=590°F WBP=518°F
NEO SUPER DOT 610 - DBP=610°F WBP=421°F
MOTUL RACING 600 - DBP=593°F WBP=420°F
MOTUL DOT 5.1 - DBP=509°F WBP=365°F
ATE SUPER BLUE - DBP=536°F WBP=392°F
VALVOLINE SYNPOWER - DBP=503°F WBP=343°F
ATE SL - DBP=500°F WBP=329°F
CASTROL LMA - DBP=450°F WBP=311°F
AP 551 - DBP=528°F WBP=288°F

Interestingly the stated service life of one of the better quality brake fluids available, Castrol SRF is 18 months and shelf life is only 2 years;
