I'm wanting to clean up firewall on my 63 C10. To accomplish this I was thinking about relocating the master brake control underneath the frame, which I understand was standard on 1955 - 1959 GMC's.

Anyone ever done this or know of some kind of kit that would provide master break module and linkage for brake pedal. Also the down side (other than maybe checking fluid level)?

Appreciate any and all input.

You might want to ask this on the 49-54 passenger car forum. On those cars the stock brake pedal mounts on the MC and several companies make dual MC and PB conversions which keep the stock pedal. However, you might have to fab your own frame bracket to mount the conversion assembly on. This is because they are designed to bolt to the stock MC mounting holes in the 49-54 frame. Also, you will need to find a complete 49-54 brake pedal (2 pieces) to use with the conversion parts.

I can't think of any obvious downside other than the filler issue you already mentioned. You have the choice of cutting a hole in the floor or mounting a remote reservoir in the engine compartment. May I correctly assume you are running an automatic transmission? One of these through-the-floor brake pedals would look pretty weird inside the cab if you also had a stock hanging clutch pedal.

The other issue you'll encounter is the bellhousing style transmission mount location will interfere with locating the master cylinder.

You'll have to relocate the transmission mount to be on the trans, tail shaft, and eliminate the bellhousing mount.

Certainly doable.

Another thing to consider is exhaust routing.

When I built my '31 Tudor hot rod I used a under floor brake master cylinder. That type of setup could certainly be retrofitted into you '63.

But it will take a person with fabrication skills to pull it off.

Here's a link to a Speedway kit: http://www.speedwaymotors.com/Speedway-1947-54-Che...

Here is one intended for 55-59 trucks, which also mount the pedal on the MC like the 54-earlier passenger cars. The overall concept is similar to the passenger car setup, but the MC mounting arrangement on the truck is quite different. Since the truck has bellhousing mounts, this type might be easier to adapt to your frame.

Truck still has Manual transmission. May be able to work with the reverse direction master cylinder. Did you run brake lines through floor or firewall?

I'll do some more investigation and see what I can come up with.

Appreciate the feedback

You kind of lost me there, or maybe I lost you. I was talking about an underfloor MC mount, not inside the cab.

I was asking about an under the floor set up.

The link to Speedway that Lakeroadster sent had the reverse type master cylinder.

Not sure what I am going to do just yet.

That's what I thought. So why would you want to run any brake lines through the floor or firewall?
