Even tho there were no instructions the installation was quite straight forward but a new hole needed to be cut through the firewall as it did not line up with the stock hole.

1941-1946 1/2 ton Chevy GMC Truck P B "Pedal" assemby

October 11, 2015
Installed on my 1946 Chevy Truck. Perfect fit and solid mount to the chassis. No modifications were needed. This is much more secure and solid than trying to use a firewall mount brake assembly. 7 inch dual diaphram Corvette power brake booster and master cylinder mout perfectly to the bracket. Can only be used with an automatic transmission !
Yes, I recommend this product.

Complete and everything fit

May 09, 2010
I installed this last summer. Everything fit as it should. The price is attractive. The edges of the pedal arm are rough stamped, but are not very visible when installed. I installed it with an 8 inch double diaphragm booster and a 1 and 1/8 bore master cylinder in a Disc / drum brake setup. The brake pedal feel is good.
Pros:
  • All the parts fit
Yes, I recommend this product.

Part # 91031411 is an excellent choice for a master cylinder. Part # 91031353 is a very basic and popular choice for a proportioning valve.

Yes this pedal assembly is designed to work with a 7” dual booster and the GM Corvette style master cylinder. It will clear fine with your 700R4 transmission.

Pedal assembly number 91031977 is for the 47-54 Chevy pickup and uses the common power brake booster pattern of 3 3/8” center to center both vertical and horizontal. You will need to verify your booster mount pattern to confirm fit.

booster and master cylinder kit 1950 GMC 150 What booster and master cylinder combo do you recommend for GM front and rear disc breaks out of a 82 camaro? I would use the Wilwood proportioning valve with 2-psi regulators for both the front and rear. Application is a 1950 GMC 150 Longbed. Looking for something more performance orientated. Thanks!

The key to power brake performance rests in the available vacuum to the booster. For full power assist you will need 18-20 inches of vacuum at the booster. For 4 wheel disc you can upgrade to 1 1/8” bore master cylinder as long as you have sufficient vacuum. Along with the 1 1/8” master a dual diaphragm booster would be recommended. Part number 91031432 with 7” booster or 91031414 with 8” dual diaphragm booster. Part number 91031977 would be a pedal assembly to work with either master cylinder and booster combo.

As you can see the brake mount is set up for a booster, but can be used as a non power brake booster by using 910-31402. The only thing that you would have to do is play with a length of the rod. Rod part numbers are 91031520, 91031522, 91031524 and 91001726.

This will not fit a boxed in frame. The pedal asm bolts to the bracket and that bracket bolts to the frame like the stock pedal asm. the frame bracket part of this kit bolts inside the channel of the frame, putting the pedal asm about flush with the outside of the frame. you might be able to just mount the pedal asm to the boxing plate.

Part # 91031977 This pedal assembly has a two part bracket and designed for an open frame. With modification of the initial frame rail bracket it could be used on a boxed frame. It will not work with factory clutch hardware.

Pedal ratio is 6.5 to 1 and if so desired by drilling two holes the pedal assembly could be used for manual brakes with only a master cylinder.

Which booster/master cylinder assembly is best? For a '50 Chevy pickup, what would be the recommended master cylinder and booster assembly for a disc/drum system with this pedal? Static proportioning valve or adjustable? Is there a pre-bent lines kit for this application? I really like the idea of the underfloor, frame mounted brake assembly to clean up the firewall on my restomod, but need some advice on what else I need.

With disc/drum we would recommend part number 91031411 which is a dual diaphragm booster with 1” bore master cylinder. You will need 18-20 inches of available vacuum for the booster to get full power assist and we suggest an adjustable proportioning valve to enable precise metering front to rear. Number 91031353 would be just one example. A pre bent line kit for your truck is currently not available. The master is plumbed with outlets on both sides for ease of installation and plumbing.

I have a frame that has been modified with a subframe from a Camaro just in front of the cab mount. It did not have any of the original pedal assemblies so I am wondering whether this will bolt up or if the original location has been removed due to the subframe - can you provide a picture of this assembly installed?

You will have to take a look at your frame to determine if the area where the brake pedal is bolted to is the original pickup frame or the Camaro subframe. If the original pickup frame is still in this area then this will be a bolt in installation. If the Camaro frame or some sort of extra reinforcement extends into that area then you will probably need to modify the pedal assembly or mounting bracket.
