66 C10 disc brake question

[1966burb]

Anyone used a factory Power Brake booster on a 1966 C10 and changed the master cylinder over to a dual cylinder when doing a front disc brake conversion? J

Ive used a similar booster from a 1966 Impala on several trucks. Its the same booster as a truck just different mounting to the firewall. Disc brake master fits fine and truck stops great. Heres my 66 Suburban .

Jon, I know it's years later , but I'm working on the power dual drum conversion to my 64. I bought a 67 booster and mc but don't have the brackets. I see you mounted your booster right to the firewall which is what I did, but h9w did you deal with the pushed to the pedal?
I measured pedal distance off the floor on another truck I have then made an extension to he booster rod based on that. It acts like there is not enough travel on the rod from booster to mc
(1 1/4"),but I don't know what it should be. Any help would be much appreciated!!

That looks great! Do you have front and rear discs? Is there a proportioning valve somewhere in your system?

[60-66]

Thank you. I so far don't see the need for rear disc's , but then maybe my truck isn't fast enough ? Yes you should run a proportioning valve in the system, heres how I did mine, some put it under the master cylinder but this is how the late 70s 80s trucks were so I ran my lines like that for a cleaner more concealed look.

Very nice it all look brand new even the frame

60-66 Thanks for sharing. Hiding the proportioning valve was a great idea. That was going to be my next question. Did you custom build all the steel lines? Jim

[60-66]

Yes, had to in order to do it this way. Last one I did I tried this new, Copper nickel I think its called ? Brake line , bends and flares very easy . The steel brake line corrodes to fast here in the rust belt , not that any of these get driven in the winter though. Just had to replace every brake line in the 2000 Chevy I bought new.

You did an amazing job on those lines!! What kind of bender did you use?

The one that looks like a pliers? Jim

[60-66]

Yes, the pliers and by hand. The loops by the master cylinder I wrapped around a piece of PVC tube .

I used one from a 74 year model. Wilwood proportioning valve. I just cut a piece of aluminum stock and drilled some holes in it to support the valve. This is a thread I did on my swap. http://www.67-72chevytrucks.com/vboa...isc+brake+swap You might want to talk to Capt Fab. He makes a bracket so you can used a late model booster.
