great fit and function.

March 05, 2015
I purchased this assembly to go in a 1934 auburn street rod build. It fit perfectly where I needed it to go and looks and functions great. I was surprised to find all of the needed peices to lengthen the rod in the kit. The dual diaphram is good for the big car and still small enough to not get in the way under such a small hood with a big block cadillac engine. The price was good and the quality seems to be all I could ask for. Overall, I am well satisfied.
Pros:
  • Adjustable
  • not bulky
Yes, I recommend this product.

Pros:
  • quality product.
  • Easy To Install

Works like a charm!

July 19, 2014
Installed one of these in my 1947 Lincoln Coupe. Wasn't room under the floor for a booster, so I went this route. Easy to fit, only required a hole in the firewall for the push rod and a mount to the dash. The master works great with my 12" Lincoln front and 10" Fairlane rear drum brakes, you'd think the car had discs it stops so good.
Pros:
  • Easy To Install
Cons:
  • can't get with a chrome master cylinder
Yes, I recommend this product.

With the many adjustments on the kit 9106002 It should adapt to your 47 fairly easily. The one inch bore will work for 4 wheel disc if you have sufficient vacuum of 18-20 inches you will have superior stopping power over manual brakes.

Dual booster with 1& 1/8 bore mc? I'm using your disc brake kit that uses a 74 f truck rotor and the pre 77 large car brake calipers for early for a 5x5.5 pattern on stock Spindles and see that the original master cylinder for the impala would have been a 1 & 1/8 inch bore. I currently have a manual master cylinder and think it stops poorly so I'm looking to upgrade to power this winter and figured that going with what was used stock as far as the bore size would eliminate some of the guess work from the new set up. I see you offer a dual boosted 1 & 1/8 mc with out a pedal and wondered if there were an option to buy this pedal with the bigger bore mc? I just don't want to assume the one inch is enough and then have it fall short of my expectations

Sorry this pedal assembly is only available with a 1" bore master cylinder. The two largest factors to consider when choosing master cylinder bore size are the pedal ratio and if there will be a power booster used. This master cylinder is sized appropriately for the pedal and booster being used. It has proven to be a highly effective combination on a wide range of brake systems, many of which are similar to yours.

No a proportioning valve is not built in. We suggest an adjustable proportioning valve such as 91031353, 91031358, or 83526011179

If you have some fabricating skills, yes. As far as just bolting in, probably not. You will probably have to fab a dash mount and for sure cut the hole for the push rod and drill for the mounting plate.
March 03, 2014
EricM
The pedal assembly with booster and master fit almost every application and can be shortened to fit your 54 Special. This mounts the booster and master cylinder under the hood and you will need to verify the flat surface or fabricate the necessary area to mount. The pedal assembly portion mounts under the dash and is strengthened mounting to the dash itself. It is no a direct bolt in and will take some fabricating to achieve the desired results.

Is the tab hanging off the front of the bracket for an electric brake switch mount or is it for structural support?

It is for support or mounting the pedal. This unit does not have a provision for an electric brake light switch but one could be added to it if you fabricate the brackets to mount it.

You inquired about a chrome booster and master cylinder and we offer part number: 91031461 that would be recommended for your application. Your Cadillac is a heavier car and the dual diaphragm booster with one inch bore master should handle your application. One warning that comes to mind right away is vacuum requirement. You will need 18-20 inches of vacuum available at the booster to get the full power assist. If less than that you can not expect full assist gain from the booster. This is a polished stainless booster and chrome master cylinder and the cost is $337.99 and if ordered before the 10th of this month qualifies for our promotional holiday shipping of only $6.99 by ups ground within the Continental 48.
