master cylinder question 17 vs 19, 2 electrical connections vs one connection ?? Options

[jimkelly]

i think the one i just installed is a 19.

instead of having 2 male electrical spades on it - it has only one and a rubber nub in center - which does not match up with the 2 that i have on my harness?

do i need to get a pressure switch from a 17mm and replace the one on the 19 ???

i also just replaced the brake lines thru tunnel and in engine bay and installed prop valve on passenger side. not pretty but should suffice??

also - is there supposed to be a washer between tha banjo and the mastercylinder or just between banjo and male/female dohickey that holds banjo in place?

The difference in piston cross-section area is about 25%. So you are effectively reducing your leverage by 25%, so you have to push 25% harder to get the same braking effect but the pedal moves 25% less.

The brake warning switch with one terminal grounds through its threads. The one with two poles grounds through one of them--which is hooked up to a plain brown wire.

To use the single-terminal sender, just hook up the brown wire that has a stripe (forget if it's a white or yellow stripe) and the the plain brown wire up out of the way.
