1964.5 mustang front drum brakes, upgrade to 4 lug disc brakes.

So currently I am working on my 1964.5 mustang (I6) to upgrade the front brakes from drums to discs. I have looked around and found on Cj pony parts has an entire conversion kit, but cost 700-1000 dollars depending on quality. Then this got me thinking, what other cars offer a same lug configuration as the 4 lug 1964.5 mustang and found a user who posted this list.
'86-'90 Acura Legend
'95-'00 Acura 2.5TL
'97-'00 Acura 2.2CL & 3.0CL
'91-newer Geo Metro
'91-'94 Mercury Capri (FWD)
'90-'02 Honda Accord
'92-'96 Honda Prelude
'86-'04 Hyundai Excel, GLS, Elantra, Scoupe, Sonata
'86-'00 Hyundai Accent
'97-'02 Hyundai Tiburon
'91-'02 Infiniti G-20
'90-'92 Infiniti M-30
'01-'04 Kia Optima
'85-'89 Mazda 323
'83-'87 Mazda 626
'86-'92 Mazda RX7
'89-'98 Mitsubishi Galant + Mirage up to '92 + all Cordia, Tredia, Precis, Expo
'80-'86 Nissan Sentra + Pulsar
'84-'88 Nissan 200SX (4 cyl only)
'89-'95 Nissan 240SX
'85-'88 Nissan Maxima
'00-'04 Nissan Sentra
'93-'01 Nissan Altima
'84-'02 Plymouth Champ, Colt, & Vista
'89-'98 Suzuki Swift, GTI
'04- Suzuki Forenza & Verona
I can't remember the user, but if I find the page I will be sure to edit their name in.

But with this list I began to think if I can use the front brakes of any of these cars to switch my cars drums to discs. I know that only a couple of these actually use discs, but I was wondering if it is possible to upgrade the brakes with a front brake system with brakes from another car. I know this sounds kind of confusing, but this is the best I feel I can word it, but I am always open for questions. Also I am a new user, so sorry if I am slow or act kind of stupid.

Look for "Scarebird" disc brake kits. They mix and match rotors and calipers to come up with 4 lug disc brakes. Scarebird sells the mounting brackets and lets the user scrounge up the rotors, calipers, hoses, etc.

That Scarebird kit looks to be the most cost effective without reinventing the wheel.

I went with this kit here: https://www.ebay.com/itm/1964-1965-1...MAAOSwZlZaDdkj

A bit more but was convenient to not hunt down parts. The only part I added was a residual pressure valve and adjustable proportioning valve. The kit uses a GM caliper that is found in tons of cars and uses a MKD 289 pad or equivalent. I ditched the cheap Chinese pads and installed some Hawk pads to go with it.

If I were to hunt down rotors from any car on that list, I would go for the Rx7...they were 4 wheel disc for later years(though, like the mustang some were 4 lug and some were 5 lug) and probably the only one on the list that hubs might be old school enough not to give you a problem....what about a RA27 Toyota Celica?(76-77) they were 4x114.3(4x4.5") and considering I used to own one, I know for a fact that they were the old type of hub-in-rotor...not the newer press in BS.



I miss that car...I swapped in a 2.4L Turbo that was essentially a Neon SRT-4 engine converted to RWD(almost anyway...there was some interested lego block building of that engine)

I would want to use those types of car, but the problem it is hard to find them in junkyard. This also means that there remains a premium if I buy the parts online

The good points for the Scarebird setup is you don't have to scrounge junkyards for the parts, they are relatively cheap at any auto parts store, and even cheaper from places like Rock Auto. The only obstacle is the stock hubs need to be machined or replaced with the Scarebird hub. As stated, the rotor, caliper, and hose required were used on millions of cars, very common items.

Use 79-85 Cadillac Seville hoses ($15), Nissan Stanza rotors ($30), with Citation calipers ($50).


Stock 14" wheels will fit with this kit, so unless you have a relatively rare 13" wheel, you should have no trouble.

Amateur restorer. Well, sometimes I have been paid for it. But not right now.

'Most' 14" wheels... I installed the kit on my '59 Fairlane and was told the same thing, but the 14" wheels did not fit. I had to scrounge up a set of 14" chrome steels and they fit fine. I also had to grind a little bit of the bracket for clearance on the spindle. Not a big deal at all, but not a direct bolt on either. Overall I'd definitely use the kit again

Working on old cars teaches us patience... and every curse word imaginable!

My experience has been that junkyard brake rotors and calipers are typically "junk". Don't forget with a swap to front disc brakes you'll also need a new master cylinder and proportioning valve.

Why, exactly, do you want to change from your existing drum brakes? The only real issues, as far as performance goes, are lack of fade resistance and "flooding" potential. If you aren't autocrossing (which I wouldn't do on 6-cylinder spindles, anyway) or towing a trailer down long steep grades and know to lightly ride the brake when going through standing water, the drum brakes work fine and, if you ask me, actually have BETTER stopping power with less pedal effort.

I agree...I wouldn't use junkyard rotors at all(buy them new) and if you use junkyard calipers, make sure to rebuild them first.

I have the stick 14's and also saw that according to the kit, I can use 1990 Chevy Celebrity Caliphers and Infiniti g20 rotors, so I am going to use those and use inifinti g20 wheel hubs. I am not sure if the wheel hubs of the g20 will work though, would anyone happen to know, because I want to avoid having to machine them and buy new ones.
