Looking ahead in my project, what do you guys recommend for an under the floor master? I will have 4 wheel disc. I've been reading on the topic and it seems I can stay manual with a 1" bore master. For simplicity I may do this. Looking at speedway I see a universal unit, but the reviews aren't stellar. Anyone know of a better unit? For a 41 ford sedan. Thank you!
I would use one for a manual disc brake Corvette....I stay away from power brakes because of cams with low vacuum...
I have four wheel disc brakes and bought an aluminum M/C from Pete and Jakes and it has worked great for many years now.
This was the go to for manual disk/disk on hot rods long before the aftermarked dudes came up with brake kits. Then the 2 lb residual valves as they take the place of the check valve in the original under the floor master cylinder. Drum brake dual master cylinders usually have a check valve behind the seat for the brake line but disk brake master cylinders don't have that check valve.
I am using these on my custom Volvo - Front disk/rear drum - with an adjustable proportional valve on the rear hydraulic circuit. Lots of interstate miles, and I am very happy with the braking performance. After about 5 years, it started to drip out of the rear rubber boot. I replaced it with new identical unit. Russ
In my truck I found the best underfloor master to use in it was the original one…bolted right in and works like it was meant to be there.
Your question is as concise as "How long is a rope?" There are a TON of variables. Bore sizes of the MC and the Calipers are important #s. You need to design the system with a MC that matches what the OEMs did. I keep a copy of the Wagner "brake bible" to match numbers. So, that said, what are your caliper bore sizes front and rear? Once we know that we can recommend the right size MC. Until then you are pissin in the wind
For reference, I'm running four wheel disc brakes on my heap (Speedy disc conversion on the front, 8.8 with factory discs). I'm using a 1" bore Corvette style master without a booster, 2# RV's front and rear, and an adjustable PV. All works well.
Good point, I didn't even THINK to ask the power question since there is no way I would ever put power on one of my own rides!
AMC master cylinders work great under floor. They made a drum drum dual master and depending on the car and year the ports are on either side. I used one on a 47 Chev pickup.
As stated in the original post, I have read I can get away with manual brakes using a 1" bore master. The rear are stock ford explorer calipers, and the front are gm midsize calipers in the speedway conversion kit. I would like to stay manual for simplicity. I do realize I will need a residual valve. I like all the suggestions on brands, the Corvette may be the way to go it seems.
I like my twin piston Wilwood with remote reservoirs. Have one in each of my Studebakers. I mounted the reservoirs in one car on the inner fender panel, the other car on the firewall. https://www.wilwood.com/MasterCylinders/MasterCylinderList?group=Remote Tandem Master Cylinder Second assembly down.
