Bronco Brake Master Cylinder Replacement Need

[68bronco1x]

I recently purchased a Used Brake vacuum booster and mounting bracket for my 68 bronco off Ebay. It was missing the master cylinder. I believe the bracket and booster is an 8 inch double diaphram type sold by Tom's Bronco.
My braking system is factory drum (F) and drum (R). I am looking for a master cylinder that will work with this set up with connections on right or passenger side. Need to know part number of master cylinder that will work...such as manufactures, Raybestos, Centric, Bendix, etc. Anyone have any ideas. Would have liked to have gone with disc fronts but because of my limited budget unable too. The 68 bronco will have 33 in. tires and only be an occasional street driver.

There is a want to buy section in the classifieds. That would be the best place to post.

Shouldn't be a problem to use this same master with upgraded disc fronts later. So you're likely good there.
Whatever listing for a stock '76 or '77 Bronco at your local shop would work, even though it's listed for disc brakes. Many of us, myself included, used our stock drum masters on disc conversions when we were not going with power assist.

Here are the ones we sell: http://www.wildhorses4x4.com/category/s?keyword=master+cylinder
Our most expensive one, the Heavy Duty master, has ports on both sides and is compatible with your factory style booster. But our least expensive one is (if I remember) the one for the '76 and '77 with the proper orientation of the ports.
And it's got a slightly smaller piston too, which will give you an easier pedal for the same amount of pressure.
I'd prefer the stock type in your case.

You will need to come up with a solution to your brake light switch. Either create a new location for your old pressure activated one with a custom brake line and a "T" style junction block, or figure out a way to mount a mechanical one to your pedal.
For that you could use a factory Ford Bronco type, which might be hard to do, or a non-Bronco plunger style switch as used by Ford and GM on many vehicles. A simple angle bracket out of some plate should work well.

Or you could also kill two birds with no stones, and use a proportioning valve like the Wilwood with it's own integrated switch. Seen here on the right: http://www.wildhorses4x4.com/category/s?keyword=proportioning+valve

I'll try to get the Centric number for you as soon as I can grab my book. We sell Centric brand stuff, as well as others, but use our own part numbers. Obviously buying local saves you some shipping cost, but if you're ever ordering anything from us anyway, it's not such a burden when adding another part.
And this kind of stuff ships USPS as well, which saves even more usually.
Of course, you could just call your local auto parts store and get the same number, unless you're still looking for an alternative to the stock disc/drum master?

Good luck.
