I have a 1977 ford f250 2wd and I did a brake conversion kit on the rear axle to disc and I’m needing to find a master cylinder that will work with my disc disc system I was wondering what are some master cylinders y’all would recommend? And will I have to change the booster?
With 5158a here.
First contact would have been to the kit mfg.
Surely they have designed the system with this issue answered.
Supprised that KIT did not address this from the start in the directions.
It is not a disc/disc MC, but would work just fine.
The mounting holes might require slight modification with a drill bit.
3 benefits over the horrible cast iron OE one :
1. Fluid level checks at a glance
2. Air not allowed into the fluid upon checking
3. Reed switch can be easily wired to a 'fluid level' warning light which is a far superior warning system than the crap ''pressure differential'' OE setup.
The above pictured dual diaphragm booster should be more effective than your OE single diaphragm one (without the crap MC. LOL)
I assume you had to fit different e brake cables. (Flat faces as opposed to diagonal faces)
That said, I would follow the above two suggestions first.
I appreciate the suggestions and I will look into them for sure! I did just remember this master cylinder on summit I found awhile back I actually bought it but returned it because idk honestly lol but it’s a disc disc master cylinder and it fit on my oem brake booster I wounded if that would work? https://www.summitracing.com/parts/sum-760119?rrec=true
On the website summit racing it has the bores are 1.125 inch on the MC and I was thinking about using it for the look and i was going to remove that valve and just use the one I have already so im not making new brake lines
my calipers are factory in the front single idk the bore size but the rears from lugnut 4x4 there 2 5/16 bore single caliper
So how it all started was I wanted to run full disc because I wanted to I had two other trucks with drums and I wanted it to be easy to maintain and everything but I sold all my drum parts so its little to late to go back
on the master cylinder I thought it had to be a disc disc master cylinder I honestly didn’t know I could run my factory setup with a single diagram vacuum booster and a disc and drum master cylinder
