Disc Brakes

I have a 1974 Ford F100 Ranger XLT 4x4. I would like to put disc brakes on the front of it in the not so distant future. I have just started looking around for this and was wanting to get everyone's input on what would be the best way to get it done. Thanks in advance.
Michael

Replace the front axle with one from a 76-79 f100-f150. Its a bolt in deal you just have to find one with the right gears.

Do a chevy disc brake conversion. You need the spindles, backing plate and calipers from a 72-76 chevy blazer 4x4 or GMC equivalent.

1976/79 F100/150 4X4's came standard with disc brakes. Do what leadmic suggests, and stay away from chevy parts. (what is the world coming to?) The wheels/bolt patterm is different, and all sorts of problems will develop trying to adopt Chebbie parts to a Ford.

Just curious, Bill. Would the master cylinder and proportioning valve have to be swapped in also? Anyone?

Yes, the master cylinder is disc brake specific. The proportioning valve changed in 1975 on ALL F100/150's.

1973/74 F100/150 4X4 drum brakes only proportioning valve = C8TZ-2B257-B

1975/79 F100/150 4X2 & 4X4 disc or drum brakes proportioning valve = D5TZ-2B257-B (drum brakes only on 75 F100/150 4X4's)

I'm considering the disc brake axle swap on a 1973 F100 4x4 that I am building for my father-in-law. Would a front axle swap from a '78-'79 Bronco work as well?

Thanks

Bill, does this mean that the axle housings are different for disc and drums or could I tranfer parts from a donor axle without cutting or welding?

The earlier drum brake axle housings are the same as the later models, so you can either swap the whole axle (if the gearing matches), or you can keep the original axle and swap everything from the ball joints out.

You can also swap the 3/4 ton stuff from the Fords with Dana 44 axles or the Chevy stuff similarly. But I agree, what is the world coming to if you put the Chebby stuff on your truck???

Theirs a disc brake axle on Ebay right now that will fit (not sure about the gearing). Last time I checked it was at $150.00 and no Im not the seller. This is just a example of how much easer and more economical it can be just to replace the whole axle.

How about switching over the tie rods too...


A beat up old ford is much easier to find than a blazer. You can swap out the whole axle or just the end parts from the spindle out. Its pretty easy and no trying to mess around with chevy parts...they would leave you stranded anyway

Sounds like a doner 76-79 front end is my best bet. I run across a complete truck around here ocationally. My next question is what about the front hubs? I have full time 4 wheel drive. I read somewhere that the only way to convert this to manual locking hubs is to modify the transfer case as well as the hubs. Can someone help educate me on this that has actually done the swap or either knows for sure if this is correct. It doesn't bother me that it is full time, I am just wanting to know in case my doner truck has manual. Thanks in advance.

If your donor truck ends up having lockouts on it already (and they're in operable condition), that's great - just one less item to have to purchase when converting the full-time T-case. Mile-marker offers the part-time conversion T-case kit for the 203 T-case.
