Disc conversion nightmare

[6'9"Witha69]

Speaking of which make sure you are using the right hole in your pedal. I believe it's upper for manual, lower for power but maybe someone else can confirm since I'm going on memory atm.

You are correct.

Finally drove car! Brake pedal is still a little low, but not that bad. Cannot lock-up brakes. 1" bore is apparently to big. Before I change master to a smaller bore I wanted to get feedback. Should I look into the step bore master mentioned in another post? Sounds as though it will possible solve my effort and slightly low pedal feeling.

Just source a 7/8 disc disc master cyl and give it a try it should raise the pedal feel drasticly. as the force you are applying is going to build peak preasure faster and giving you a better feel.
Alos do you have residula pressure checks all the way around (ie front and rear if not the fluid has to rebuild "take up" pressure before you get any movementy and the fact that they kee pthe pads a tad closer to the rotors.
I am goingto work out a set of rear disc for my Monza soon but gotta get it running first.

Seems some people are for the residual pressure valve and others feel it is not needed. If I change to a 7/8 disc/ disc master does anyone know year, make, and model of donor vehicle so I can tell my auto parts guy?

Thanks,

I would also like to know of the application.... Anyone?

Uh pretty sure that none of those are actually speced for disc/disc
I guarantee the Monza isnt.
And I would take a look at a later disc/disc 98 S10Blazer as it has a 2 piece spindle I have thought about running on my Monza and it is a drop in for Gbodies and is upgradeable to Vette stuff so I would bet it would work well with disc/disc.

Concluded I have the low drag calipers and therefor will need a step bore master
