There was a lot of information in the archives but I still have questions.
There have been several posts with master cylinder sizing and part numbers. None of those posts has information stating what MC is used with what wheel cylinder sizing. My project uses a 80s GM ½ ton chassis. That is disc front and drum rear. I have read of guys using from1” to 1 5/16” bore MC. I think the quality of the brakes can be fine with either if they are matched to the right caliper and wheel cylinder.
Does anyone have a suggestion on what MC to use in combination with my brakes?
I have the stock P30, and the stock GM truck master cylinder. From what I read, the GM unit probably won’t bolt to the hydroboost system. The bolt pattern looks right, but the snout of the MC won’t go into the hydroboost. Right? I have not taken the 2 units apart to check.
What fluid is everyone using? Power steering fluid or ATF?
Is a cooler necessary? There wasn’t one on my P30.
