Brakes (again)

[zieg85]

Ok, you need everything that bolts to the firewall...  I wish you were closer, I have one complete sitting on a shelf and I can't remember if the power booster has the bracket bolted or a part of it.

If it fits I'd make a bracket it I had to!! Would you be able to get any part number off it so I could match it up? Thats assuming it has the bigger holes as the pics above!!

yours sincerely
Mr Desperate!

Mr Desperate, maybe a bit late on the reply, I apologize.  Welcome to my other shed.... Anyway the bracket is part of the booster on mine taken from a 1985 C20 Suburban which had the full float rear end and a 454 which I am under the assumption that it is as heavy duty brakes available on a 3/4 ton.  Here is some pictures anyway.  I was saving it because it was in really nice shape in case I wanted to put power brakes on my C10 project I have in a holding pattern.  Please excuse the messy shed, it is going to get cleaned as soon as the weather breaks for good...

Sorry Vile I've confused everybody - including myself!

I have a new booster/master cylinder/resevoir complete.

I need to get the connecting rod to the pedal, hoping the Summit kit will sort that.

The resevoir they supplied has 4x 3/8-16 outlets. I need a resevoir with 2x 7/16 outlets, then I have to pray the correct resevoir fits the new booster.

Measure the bore size for the MC to Booster size and have them confirm.

from Summit tech page info bit - Master Cylinder Bore Size  1.000 in.

I've tried the NAPA links but they all come up "error" haha

Could you have another peak and see if its the same?

ta mate

Zeig, what's the adapter looking bit on the back outlet?

Zeig, what's the adapter looking bit on the back outlet?

Electric brake controller, old style which now I think is not legal.  The smaller line went inside the cab to the controller.  Now they use a pendulum to control the intensity, or at least that is what I am lead to believe.

Weird.  They don't work...
changed them, do they work now?

JB7
Brake Master Cylinder Bore Size : 1.125"
Brake Master Cylinder Line Thread Size : 1/2"-20, 9/16"-18

Nope Chris, they still don't work.

Looks like the booster I have is no good, bore too small.

I'm going to bed, nearly midnight and head is cooked!
