HELP Master brake cylinder

[FluoFerret]

For those of you that have disc/disc setups on their g-bodies: what models of master-cylinders are you using? and more particularly what bore/stroke do they have?
My current setup on the master-cylinder looks like this, and I am not sure that this is good if the bowls are not level

I’m using a factory ac delco unit. More important than the MC, is the proportioning valve. What’s your setup?

Master brake cylinder: Aluminium Tandem MC by Wilwood, with a stroke of 1,1" stroke but I have no clue about the bore diameter.
Front: D154 Calipers by Wilwood (#140-12097-BK)
Rear: Dynapro low-profile rea brake/parking brake kit by Wilwood (#140-11398)
Proportioning Valve is a standart OEM model for disc/disc

I didn't think it matters that the master is tilted. I thought most were. I'm one step behind you and have to choose a master and booster for disc/disc setup.

It does matter,the angle of those (or lack there of) wilwood job's is not very practical.its leaning so far back that you'd have to jack the back of the car up to level it off to reach the full mark. I installed one Initially but it wasn't any good.they wouldn't send me a new one,they offered to rebuild mine in house only.(gtfo it's brand new)3 strikes you're out.I'm running one from 87 monte,disk/disk prop valve,wilwoods all around with no issues

Do you happen to have part numbers for master and booster?

 

[melloelky]

i do not,it was some time ago but they're just oe replacements for a 1987 monte w/v8.the booster is the Dual Diaphragm btw.i got the master from rock auto and the booster locally through work.

 

[Tony1968]

Do you happen to remember if master has inch and an eighth bore size?
Appreciate it. I look up a lot of this stuff and many times they don't advertise specs. Even on Cardone's website. It's aggravating 😑

 

[melloelky]

I'm sorry i don't know.

Checked half a dozen sites. Looks like yours is 15/16.
Pretty sure I need 1.125 bore due to 4 pistons on all four calipers
