Re: Getting ready for a Treadle Vac Replacement

Thanx HH, this is one project I am playing with. I just picked up 5 treadle vacs to experiment with.

Obviously the smaller dia master will deliver more psi to the wheel cyl however, if gone too small, pressure can build too quickly giving a jerky peddle.

I am playing with 5/8 to 1.039 bore, any bigger may give a harder peddle.

I have the master mounting and vacuum sealing all down. I need to turn a new plunger shaft to accommodate function in the vacuum can as well as the MC plunger.

Any other thoughts as I play with this is appreciated.
