Re: [EVDL] 9" adv Aluminum feild coil housing ?

Dave,
Using my Ev for its intended purpose, commuting, I
don't have hills or mountain passes to go over. The
brakes are sized for performance driving now. I rarely
get on the brakes hard enough to heat them up. If I do
end up going down a mountain pass, I will just pulse
the brakes. This keeps them much cooler.
When I just finished my Ev, the first problem I had
was my vacuum switch cutting out. I went home several
days with non operating power brakes and yes the pedal
was heavy, but not scary. This was with fighting the
vacuum booster and lower leverage pedal. I think Ill
be OK.
Dave if I wanted to save the hassle, I certainly
wouldn't of done what I already have : )
I made a joke! ha ha, sorry its Friday , I'm in a
good mood! : )
Bye for now,
Jeff
