Speedway 54-56 Disc Brake Kit & Dual M/C?

[SWPruett]

Hello All!

Hoping for some user feedback on the Speedway Motors 54-56 Ford front disc brake kit #91032000 and dual master cylinder upgrade kit #91032008. Both kits are specifically called out to fit the Thunderbird and their demo vehicle is a ‘56 in their videos and online photos. It looks like they use the GM G-body calipers that have appeared on several other conversions along with the requisite fabricated mounting hardware and 11” rotors. The dual M/C kit uses the familiar Ford dual bowl M/C and a prop valve tuned for front disc/rear drum.

Anyone installed either (or both) of these kits? It appears they have eliminated the Midland front brake booster on their demo vehicle as part of the install but no mention is made of that. Any concerns running front disc brakes without the booster? In my mind I would think the disc brakes would be such an improvement over the original drums that the booster assist wouldn’t be missed, but I really don’t want to have to stand on the pedal to get the ‘ol girl to stop if I can avoid it.

Any first hand experience would be greatly appreciated!
