[TR] Changing from DOT 3 to DOT 5 Fluif

[Bob Labuz]

All,

I use DOT 3 in the 3 and DOT 5 in the 4 and they both have their 
original brake light switches. I have had the 3 for over 30 years and 
the 4 is in its 6th season with the DOT 5.

Maybe it is the replacement switches that are the problem?
