Hi John,

My take? Flush and bleed the system and, if the fluid isn't really dark 
or viscous and doesn't have any gunk in it take a day trip. When you get 
back, check everywhere--M/Cs and slave cyls., hoses, etc.--for any leaks 
and if none, and the brakes work OK let it be. If you use glycol fluid 
(DoT3/4) there's an outside chance the fluid could have gelled but that 
would be evident when you flush; then you'd want to do a full rebuild.

Please send $0.02 ;)

Bob
