Has anyone had experience with these Electric power brake master cylinders?

[Rooster's 67]

I was searching to find a replacement/repair kit for an unknown branded under floor -remote fill master cylinder on a 56 Chevy truck that i'm workin on and came across this in speedways catalog. Booster and master in one, and uses electric hydraulic pressure. Looks as though the pump is using the same reservoir as the brakes possibly, also looks like they are using a hydraulic accumulator of the same design/manufacturer as Lincoln did back a few years ago on their ABS systems.A little pricey but, for those of us building show trucks; two components into one, can be under floor mounted with remote reservoir, or standard bulkhead mounted and its in Billet? I want one!!!



and I found some more info at the manufactures page:

Has anyone used one yet, or had any experience personally, or anyone they know? Looks Like it was installed on Copperhead appearently.(don't know how I missed that?)

Comments?
Knowledge?

GM did some electric power brakes in the late 80' early 90's and it was a TERRIBLE idea. The picture you include looks
"powermaster " ish. I had 2 87 Buick Grand Nationals, and both of the powermasters were in the trash within a week of ownership.

My buddy had that exact setup in his '67 Chevelle. It was the biggest POS crap item either one of us seen. First one leaked so bad and didn't work. They sent him a second one that didn't leak but had almost no power boost. After dealing with this and the rear disc setup from ABS, he trashed all of this new parts (electric booster/MC, front and rear disc brakes) and went with a Hydraboost kit and 13" Baer brakes all around. System works awesome now!!!!!

Go with a stock vacuum booster or a Hydroboost system as they both work great. The electric system is total crap!
