brake booster question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**slepysal** · 10-19-2010, 03:37 PM

Will a 7" or 8" dual diaphram brake booster be good for a 1960 with a L6?
Will it give sufficent vacum or should I just run non power disc?
I have limited space and don't think a full size booster will fit.
This is my next project as I just spilt the brakes to a dual circuit drum/drum master. So No rush just looking for addvice Thanks

Do you know how much vacuum your 235 makes? The '82-'87 S10's came with either a 9 or 10 inch dual diaphram booster.

If you can find out what your vacuum is, I can check mine to see how much it takes to operate mine.

Thanks guys my '60 has a 250 in it and I truthfuly don't know what vacum it makes

Hey Sal. My guess would be that your 250 will produce plenty of vac to run that booster. 250 was a common engine option in the 70's and early 80's with power brakes. Shouldn't be a problem... Good luck! JC62

hey Jose howz it going ? Captinfab I sold my stepside to my wifes son and told him that if was going to add p/s or p/b to hit you up. 63GenIII thanks for the offer !
Got a 7" at a local swap meet I'll give that a shot ,I know that some 72's came with non power disc brakes so hopefuly it works out

Captinfab you mentioned using a S10 booster , do the push rods on those boosters need to ne modifiyed?

**Captainfab** · 10-30-2010, 12:21 AM

Yes you will need to modify most any OEM booster pushrod to be able to connect it to your pedal
