Front Disc Brake conversion

[Weapon_F]

Hi Guys,

i'm heading over to the States next month for a holiday, watch some ice hockey and see what snow is like during christmas. but i also want to get a disc brake setup to take home with me as my christmas present so i can take it back to Australia. so what i'm asking you guys is, what do i need and what truck do i need it off and do any of you have a setup you are willing to part with? i have a 1970 Bump base of the base model F100. i won't need the discs themselves, as i would buy new ones and also to save weight.

please let me know exactly what i need and if anyone can help. i'm travelling through california (driving from San Fran to Anaheim then heading out to vegas), and in NYC and Boston. it would be pretty cool to meet one or some of you guys along the way and see what these bumps can look like running, as i bought mine just "running" and in very poor shape. I've never seen a good condition one running.

cheers!

If at all possible, you should try to find either a 1973 or 1974 F100 with front disc brakes. That is the easiest swap to do. Pull the king pins out, put the spindles on, put the king pins back in and you're done. All you need are the spindles and the dust shields. The rest is available at your local parts store or anywhere online. The brake line brackets that bolt to the frame are a good thing to have but not mandatory. That's the swap I did on my truck. See my project thread starting on page 9 and scattered through around page 16. If you go any newer than 1974 then you're into having to swap I-beams too. '75 and up have different king pins and I-beams but '73-'74 use the same I-beams, just different spindles.

If you're working on the front suspension to put discs on (assuming you don't get the ENTIRE Dentside front suspension), you may as well pull the existing I-beams and radius arms on your truck to replace the bushings in them. Chances are highly probable that they are worn.

This is just a personal preference thing but, I don't particularly like the way the Bumpside radius arms look. I think the Dentside radius arms look much better and these are items that can be seen hanging down from under the truck, after they are installed.

The second major reason I elected to use the '77 F100 Dentside I-beams and radius arms on my '69 F100 is because the Dentside radius arms have a slight protrusion and a notch in them, to interface with the endlink brackets for a factory front sway bar from a '75-'79 F100 through F350. --I have a front sway bar from a '78 F250 Camper Special and a rear sway bar from a '79 Bronco on my F100.

How important is keeping your truck "all Ford"? Scarebird LLC produces brackets that use 90s GM truck calipers to mount on your drum spindles. Your drum hubs are also retained but need to be machined to fit inside 4WD 76-96 Ford half-ton rotors or 95-99 Dodge rotors (no machining required for the latter). 1/4-inch longer wheel studs are also required.

Cheers for the info, looks like the 73-74 model is the way to go for me, as i need to be able to source parts easily and i have to lug it all home. if all i need to grab is spindles, callipers and dust shields then i'll be in better shape. are the proportioning valves different from all drum to disc drum? and the master cylinder?

that kit sounds alright but its hard enough getting the ford parts i'm after let alone dodge or GM, from a US only model. i can get mid 70's truck stuff rather easily, compared to bump stuff.


so, listing the places i'm visiting, where in the US am i most likely to find these models?

10-4... if in the SF Bay Area visit http://www.picknpull.com/ ... they have quite a few salvage yards and perhaps more importantly, you can check their inventory online for 73/74 F100s. Down south there are quite a few salvage yards.. in LA, Ecology Auto Wrecking seems to be really popular. I'll keep an eye out here in the Bay Area and maybe score a set for you to just pick up. I can always flip 'em if not.

Prop valves are different drum/drum vs disc/drum. My personal preference is to get an aftermarket unit like an adjustable prop valve from Wilwood.... about $80 USD.

MC is different too.. disc MCs have a larger reservoir from the discs because it requires more fluid to push pistons than a wheel cylinder. Drum MCs have equally sized reservoirs.

PM me your email, tour schedule, and we'll set up a line of communication offline.

Easiest is just running the Dodge rotor. I'm doing this swap now. The Dodge rotors use the same bearing as your stock bumpside, so it is simply a bolt on.
