power drum brakes????
about a year ago I purchased on the parts board a master cylinder and booster and proportioner setup supposedly for a drum brake setup. I finally am getting to the point that im ready to install it. BUT, im questioning now that is there really a such thing as power drum brakes?? Any input would be great.

Re: power drum brakes????
Many vehicles had 4 wheel power drum.
Like 67 Buick Electra 225. |

Re: power drum brakes????
One thing, though, all-drums do not use a proportioning valve, just a distribution block.
edit: ya beat me by a minute while I was typing!

Re: power drum brakes????
But, they didn't have a proportioning valve with drum/drum brakes. A dual chamber master starting in '67 would have had a distribution block that contained a switch. That switch operated a dash, brake lamp to indicate a malfunction in either the front or rear brake system. That lamp would also be lite by the e-brake.

Re: power drum brakes????
Absolutely. My '70 has them. work better than the manual, and my wife can drive it. Haven't yet been able to justify the cash outlay to upgrade to Disc yet
