I'm preparing to convert my front drum brakes to disk, the back will remain drum for now. I've read that a "dual master cylinder" is in my best interest for safety, but technically not required. Question: What are a few recommended companies that make a good after-market cylinder? Make: Chevrolet Model: Impala Year: 1964
How about AC Delco? https://www.performanceonline.com/Disc-brake-Master-Cylinder-Proportioning-Valve-Kit-18817/
nothing like using a factory one ( AC Delco) , available in many bore sizes and often a 1/4 the price of the aftermarket ones and 1/2 the trouble setting up the system too , as you can adapt the proven system over . and it often contains the proper combo valve with the proper settings .
The GM is good I went withe the wilwood master and control valve set up , And while you're at it loose the booster and go with hydroboost, it really adds to brakeing
ECI seems to know their stuff. http://www.ecihotrodbrakes.com/index.html My father, RIP, wasn't a mechanic but knew I was born a gear head, his best advice was "never compromise on brakes or steering"...and something to do with loose women. Made sense to me as a kid, still makes sense to me today.
For a Chevy I'd select a '72-75-ish Chevelle master and matching booster if you wanted power brakes. At least you know where it came from and you can get parts anywhere.
That looks to be a good deal, but I'm guessing that they're not genuine ACDelco parts. The description only states that the kit has an "AC Delco type proportioning valve" and there's no mention of the source or country of origin.
The current master cyl is located in the stock position (firewall driver side) and the current drum brake setup includes a stock power brake system. Will this dictate the dual master cyl type I need?
Check out ECI at this link, it has the answers to just about anything you need to know to do a disc brake conversion http://www.ecihotrodbrakes.com/brake_facts.html
The right stuff is where I got the conversion kit for my mom's 58. The parts in that kit are available at Napa. They were reasonable, and the kit was from 58-64.
