Extremely Heavy Duty Construction

I'm currently installing this brake unit in a 1928 Model A Pickup and am quite impressed by the extremely heavy duty construction of the brake unit......3/8" gold-anodized steel. So far, although the firewall and floorboard areas are extensively modified, I've been able to install the unit successfully. Only one drawback......the link provided between the pedal unit and master cylinder is way, way too long. Even if you screw the actuating rod completely into the heim joint, the pedal end of the brake lever is so far forward it almost touches the master cylinder. I will now have to fabricate a proper-length rod to complete the installation.

Poor design

Had to wait due to Backorder. When arrived I found the clevis and pushrod were 1/2 inch out of line with the bore of the master cylinder. Had to modify pedal and mount in order to align pushrod into master cylinder. Poor manufcturing

Everything came as advertised. I like the resources Speedway has for installation info. I wish they had a bigger YouTube presence, but I also realize that with such a broad spectrum of products offered, there's no way they could cover it all.

Hello, I just installed this on my 32 3 Window Coupe. The brakes are going to the floor. The master cylinder has been bench bled and brakes bled. I am using this on 4 wheel drums. Do I need 2 residual valves for this set up? Do I need a proportioning valve set up? Thank You.

In the product description to says it will mount to a stock or boxed frame, my question is how would it bolt to a stock Model A frame? Is an additional bracket required to attach to the pedal assembly and then to the unboxed frame rail. Just a bit confused.

What would the measurement be from the front radiator mounting hole on a stock model a frame to the center line of the brake pedal pivot bolt be? Or maybe the distance from the frame/body bolt hole that is on the top of the frame just forward from the average pedal pivot location? Also can the pedal arm be shortened? As in the part where the brake pedal would be attached without affecting braking effort?

Another question about this brake assembly kit I bought 91631926. Doesn't the push rod need to be inserted into the master cylinder, to prevent the pedal from being loose and falling all over the place? What holds the push rod into the master cylinder on this kit?

I bought this kit for my 1932 street rod, will this work for my 1932 Ford frame, it is a boxed in frame and this says it can be welded to (boxed or stock) but this has a bolt sticking out the back side that holds the pedal on? Won't this create a problem to be welded to the frame? The assembly will not fit flush to the frame! Also do I need a brake booster with this kit or will it work without a booster?
