Hot Rods Hanging pedals in hot rods, 1960-62 C10 M/C

I have been doing a little research for the next project I have waiting in the wings.
I think I may go with a 60-62 GM pickup master cylinder. I have a couple of questions.

I love the looks of this.... @daddy_o's_diner


What pedals did you end up going with?
Use the pickup pedals to match the MC or did you fab your own?
Did you plate the inside of the firewall?

 

x2 on the Ansen pedals. Had that setup in a chopped 34 ford pickup. Worked really well.

 

I read somewhere on the HAMB that Lucky's used to make a set, improving on the Ansens. I doubt they are still making them.

 

Dumb question. Are all of the 60-62 master cylinders 1-1/8" ?

I don't guess a guy could bush them down smaller? Just thinking out loud here.

 

I would think so, but I have read quite a few threads on the old interweb talking about ratio issues. Just thinking it might be nice to get out in front of that. I think the F250 brakes have a 1-1/16" bore.

 

I think I still have my pattern if you want to make your own ansen style pedals. We made a couple sets, a little improved over the originals

 

You know it Holmes....

 

Let me look in my patterns

 

Thanks.

 

Trent,

Don't worry about looking for the patterns. Rjays sells his cheaper than I could fab my own.

Good deal!

 

Another vote for R-Jays, Have used a couple sets, he has lengthened the pedals a little bit to improve the pedal ratio and allow you to mount them a little higher on the firewall for esthetics inside and out.

 

You asked about bracing. Most factory hanging pedals are attached to the firewall and dash. I have noticed firewall flexing on some vehicles even with that being done on non factory applications. Usually on non power set ups.

 

I used the Ansen pedals when I put my 32 together in 60-61, had my Dad make a re-inforcing plate mounted to the inside of the firewall.

I used the stock pedal assembly out of a 62 Chevy truck and ran a brace from the firewall to the dash worked out great on my 29 Roadster

 

are both cylinders of the master equal? didn't the original gm pedals work criscrossed? like the brake pedal depressed the outward cylinder and the clutch pedal depress the inward cylinder?

i think i was told that. i was also told you need to swap pistons on the straight forward ansen style setups or else you end up with a too stiff clutch pedal. sound right?

 

I believe it's just once common reservoir for both clutch and brake. Two separate plungers. I don't see how you could criss cross it.

 

Yes, you have to swap guts from side to side. See the above picture Root posted? You can see "clutch" labled on the right side

 

What in the nut for? Someone needs to explain this to a simple minded Okie.
I'll be disassembling for chrome anyway, so that part isn't a big deal, but I need to understand the logic. There is no way that these have passages that intersect, that I can see. Someone help me grasp this before my head explodes.

It is the difference of the internals

https://www.jalopyjournal.com/forum/threads/residual-check-valve-for-clutch.360234/#post-3900822

 

No residual pressure valve on the clutch.

 

OK, I get the reason on the internals, but what baffles me, is the fact that the inboard side is marked clutch and is a straight shot through the firewall. It would be where the brake pedal is normally. Am I looking at something wrong?

I am assuming that this was mounted on the front of the firewall facing forward.

 

Originally what will be the left side when mounted on the firewall was for the brakes and had a residual check valve on that side and what is now the right side was for the clutch. You need to swap sides to get the brake guts on the brake side and the clutch guts on the clutch side. I have sleeved the clutch side several times to work properly with various sized clutch slave cylinders. The cylinder was originally mounted under the floor on the truck and not the firewall

 

I have not worked on one of those trucks in years, It must be something in the way the pedals are set up in them. Old Wolf would have known the answer to that

 

Hopefully, I am making sense. I just don't see a logical explanation on where this cross over conversion occurs in the process. Sorry to beat a dead horse.

I assume GM didn't have the clutch pedal in the middle of the pedals for 2 years only. It's more of a learning experience at this point.

 

is there a real flat old style looking booster that takes a ford iron master - dual chamber
