Master Cylinder? - Pirate4x4.Com : 4x4 and Off-Road Forum

dunenutt · 04-30-2011, 03:56 PM

I am in the process of converting a 69 c-10 to 4x4. A soft core resto mod driver. Anyway, I used an 85 blazer as the donor. The cheap alumaplastic power master cyl looks like a$$, and leaks. Does anyone know of an old school iron master that will "bolt up" without too many mods. I know that there are many possibilities, but looking for something that will still have decent street manners. all stock blazer disc front, drum rear.

Thanks in advance.

are you asking what power booster/master combo will fit your c-10 or what master will fit the donor blazer booster that originally had the plastic resivoir attached? personally i would run the setup you got and make sure it works good, then start swapping out stuff.

anything pre 1980 then.

just tell them its for your 69 with power brakes and you will get a bolt on iron master.

sjracer, I have everything and it works. The AL master weeps around the bowls, and generally just does not look old school.

trkklr77, Thanks, I'll try one from a 71-72 because they didn't have power brakes in 69.

1979 firebird master cyl with 4wheel disc brakes. cast iron. designed to run 4 wheel discs, costs about 15 bucks, i think (last one i bought was 14 and change.) works with or without power booster. use a pedal ratio of 7:1 without power booster.

works for me.

looks like the price went up, and could be that i get my parts at a reasonable discount...

oh, hey.. not too much, look at this one:

Grumpy,

How well does the rears work if this is for 4 wheel discs, and I have drums?

Grumpy_old_fart · 05-03-2011, 10:33 PM

probably will definitely stop a set of drums dead in their tracks... it sure works for discs, they take a LOT more pressure.
