Disc Brake Conversion parts list

I know it's been covered about a billion times, but I thought I'd go ahead and list parts and sources for this swap. I'm using a 1975 F100 front end, so your list may vary a little bit.

Wrecking Yard:
1975 F100 I beams, spindles, radius arms, brake dust covers, brake line brackets

LMC Truck parts:
2x Bearing grease cap, PN 40-1962
2x Spindle nut, PN 40-0692
2x Washer, PN 40-0696
2x Cotter Pin, PN 30-2730-F
2x Disc Brake Hub and Rotor, PN 45-3214
2x Spindle Nut Retainer PN 40-0693
2x outer wheel bearing (Chinese, not Timkin, sorry) PN 45-0512
2x Inner wheel bearing (Also Chinese,) PN 40-0552

Summit Racing:
King Pin kit, brass bushings, PN MOG-8551B
Caliper PN CEB-141-65005
Caliper PN CEB-141-6006
EBC Brake Pad set, (I had to do some filing on the ears of the back ones to get them to fit, just a warning,) PN EBC-UD375
Master Cylinder and booster retrofit kit, (uses stock brake pedal), PN SUM-760214
Proportioning valve (for front disc/rear drum), PN SUM-760186
Wheel Bearing Grease, Timkin, PN TMK-GR224TUB
Wheel Bearing Seal, Front Inside, PN TMK-4148
Bushing kit, polyurethane, red, PN PTP-6-2020

All that's left is bolts, steering parts and brake lines! I haven't ordered my rubber lines yet, but they'll have 'em at LMC or your local parts store. And you'll have to make some lines from your master cylinder to proportioning valve. If I missed anything, feel free to add to the list!

You only need the hard line-to-flexible brake hose frame brackets if you have a '65-'70 model truck. The '71-'79 models have the correct, taller, L-shaped brackets from the factory.

Small, low-mounted frame bracket that would be on a '65-'70 model (this one pictured is on a '65 F100).

That's perfect! I actually pulled these off of the donor, if anybody needs them. The ones on my '72 are already the correct ones.

Don't ever let someone on here say I don't search before asking! Ha!

So the booster assembly and MC looks like it will work in my truck, a 69 250 with a Crown Vic front and Explorer rear. I have 4 wheel disks on mine and the 1.00in bore is what I am told I need, but with an adjustable proportioning valve.I also need an adjustable push rob or arm. The thingy that goes from the MC, through the booster, and attaches to the brake pedal.

I would like to order this stuff today. I need it so I can finish my firewall.

I don't know what booster you're looking to get but the Ford (Bendix) booster input rod is attached to the diaphragm. It doesn't come out of the booster housing. '68-'72 single diaphragm or dual diaphragm boosters will have an adjustable length input rod. '73-'79 boosters will not have an adjustable input rod.

The Bendix output rod on the boosters are adjustable in length.

Is there a Summit part number for that? Will that booster listed work? I could not find one with an adjustable output rod but in the reviews, someone used it on a bump and it worked.

Worst case, I could fab the brake pedal to work. I can cut and weld but if I can avoid it, I'd like to.

These are bolt-on wrecking yard donor parts (turn the booster in as a core for a newly rebuilt booster). No cutting/altering the firewall and no modifications to brake pedal required.

I have an '81 with a booster but it is WAY different than what my truck would have come with. I ordered the MC/booster, an adjustable prop valve, and the bracket. Worst case, I'll send it back for exchange. It comes with the threaded push rod extension so it should be a relatively simple bolt on affair. I've searched the junk yards but they're somewhat limited around here and I haven't found what I've needed. It was easier to go CV front than disk brake conversion.

I have not yet ordered connectors or brake lines. I simply need to finish my firewall so I can get my cab back on the frame and finish out the interior.

A booster from a '68 through about a '77 Ford truck would bolt to the firewall without modifications to the parts or to the truck itself. The dual diaphragm booster in my '69 F100 came from a '75 F350 (I traded the booster in as a core for a newly rebuilt booster). This booster has an adjustable output rod but the long input rod (between the brake pedal and the back of the booster) is not adjustable.



This is a rebuilt dual diaphragm booster for a '68-'72 F350. It has an adjustable output rod as well as an adjustable input rod. I've installed this type of booster in a '72 F100 as well as in a '65 F100.

Application in a '65 F100.



Application in a '72 F100.



All 3 trucks (the '65 F100, '69 F100 and the '72 F100) have Dentside F100/F150 type front disc brakes and stock drums on the rear but would also be compatible with a CV swap and even with discs added to the rear too.

--I had a 2003 CV front suspension but, decided I didn't really want to cut up my '69 F100 Ranger's frame to install it. I sold the CV front suspension to a buddy who will be installing it in a '77 F150 with a turboed 5.3L.

I think I found a typo
Caliper PN CEB-141-6006 should be Caliper PN CEB-141-65006

BTW, are the radius arms from the disk brake truck required or could I use my 68 radius arms?

The kingpins and everything out are different from drum to disk, but your radius arms are the same and will work. Keep in mind, regarding the kingpins, I have an F250 and different kingpin sizes were available. Before my CV swap I was told to ensure I had a certain kingpin for the conversion, and if not, to get it.

If I recall, I remember you saying in a post that you don't care for the metal MC and prefer the plastic reservoirs. Why is that?

I have the CV booster and MC and I can get the one from the Explorer I ganked the rear from, but both would require modification to work. I looked for OEM truck to pull parts from but it gets to a point when they're not readily available, it's almost cheaper to just buy new. I have been so fortunate in getting donor parts that I'm not complaining, just wish I had more around so this part would be more straight forward.

Thanks RIPbiker, that is a big help.
Also thanks to unknown cubicle as that is exactly the info I needed for my conversion.
