Brake help...

Idk if this is the right section to put this in, but here it goes

I was wondering if the brake booster & MC off a 85 1/2T will work on my 77 1/2T, other than the possibility of Metric Vs. American

I don't see why there would be any difference between the working wise, just different materials / look

Thanks, Matt

Re: Brake help...

I don't see why not. The front and rear brakes are the same stuff, but you will definitely run into brake line differences (metric/standard.) I'm sure this has been done before? Dunno- take this as moral support/free bump...

Re: Brake help...

Thanks man

I have no worries on the metric vs standard, as I have the double flaring tool to build my brake lines & I have to build new ones anyway

Thanks for the support lol

Re: Brake help...

The newer master cyl might have the GM 'quick take-up' design vs. the old unit. I'm not sure if there would be a variance in the prop valve to accommodate this so I would use the later prop valve as well.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
