Default Disc brake conversion question.

Hey guys,
I have spent the last few hours doing some research but I am just confusing myself some more. I have a 1967 mustang ( 5 lug V-8 ) and most articles I come by discuss a Granada, Falcon or Fairlane swap of some sort. While cruising my local junk yard this morning I came across a 66 mustang with disc brakes.

A set up off this Mustang would convert over wouldn't it? What parts would I need, for instance would my current spindles be fine since they are 5 lug? I guess I have questions because there must be a reason why this is not a popular swap and most articles cover the Granada etc.

Did I just not look hard enough and maybe the 66 junkyard stang was a 4 lug rotor? I remember it being a V 8 car, I thought the 6 cylinders were the 4 lugs only but maybe I am wrong. Any help would be appreciated since I would like to go down and get them before someone else swoops on them, Thanks in advance - Ponyyboyy

You have the ABSOLUTE Correct spindles on you Classic right now to install the 67 Factory Correct Shelby style Disc Brakes.

To put Granada Brakes on your car is a Total, uncalled for mistake--Why?

I will do some research on this Shelby swap, but when I hear Shelby one of my first thoughts is $$. Do you know if the 66 coupe disc set up work?

Just get a Wilwood kit, some of the best brakes available and affordable.

I'm with Chokostang. I have the OE-style Kelsey-Hayes brakes on my '67, which are the same from '65-67. You can bolt on the '66 brackets, calipers, and rotors without having to swap the spindles (and risk bump-steer issues from incorrect steering arm geometry). You'll need to figure replace the m/c, replumb some hard lines, and add a prop valve, but I'd ****** those brakes in a heartbeat.

Thanks guys. Can anyone point me in the right direction, maybe a link or site I can research on these shelby style brakes. I am not familiar with this at all.
@ Starfury, I am not sure I understand what you are saying, I should snag these brakes up from the junkyard or go with the shelby style? Does the shelby style use the same parts the 66 offers? Sorry for my lack of knowledge on this subject guys, I appreciate the help.

They are just Ford- kelsey Hayes calipers, it's the standard disc brake for fords and had nothing to do with Shelby. I think they changed calipers in 68?

Factoid- The 66 coupe disc brakes were- you guessed it- the exact same brakes used on the Shelby.

What's more, you can get the entire setup, all new parts (no old rotors etc to clean up, refinish, or rebuild) and the Shelby-type won't require a wheel alignment, while the Granada will- which means that Granada brakes, after a ton of work getting them ready to use, and installing, will end up costing you more than OEM brakes, and the all-new OEM brakes can be installed in an afternoon, with no special tools. You'll want the 67 of course, they were slightly different from the 65-66.

Here they are, you can have them on the car for under $600.

Shelby used whatever the Mustang came with in a given year. 65-67 had the Kelsey/Hays 4-piston fixed calipers. In 68, Ford switched to a single-piston floating caliper, which required a unique spindle, unlike the K/H, which used the same spindle as the drum brakes.

First off, I'd snag that disc setup off that boneyard '66 so fast it'd make your head spin.


But because I am just that kind of a guy, I have to buck the trend.

Why the hate for the Granada brakes? I have put them on a few 1st gen Mustangs and in every instance they were light years ahead of the factory drums.


I put Granada discs on my fastback about 20 years ago and other than changing the pads a few times haven't had to give them another thought.

Yeah, there are certainly better setups but it has been my experience bang for the buck they've been tough to beat.

Because you can get a factory KH-style setup for $600 that doesn't require changing spindles and doesn't mess with the steering geometry (Granada spindles have different steering arm geometry that can cause bump steer issues). It also makes getting replacement parts much easier; you simply walk into your nearest parts store and ask for parts for your year car, instead of trying to remember what year Granada you pulled which part off of.

Interesting comments...especially since I'm just about to install a CSRP front disc kit on my '65. I had to go with the CSRP "Granada"version of the kit, since my original spindles were ruined by a PO who welded...yes, WELDED...a set of Oldsmobile calipers to them in a "Frankenstein"conversion using rotors off the rear of a 1996 Mustang and Olds calipers!! The car stops...but not very quick.

anyone know of any significant bumpsteer issues with the CSRP kits?

I'm with fastbackford351, I've got Granada discs on mine and they work flawlessly. The car handles exactly like it did with the factory drums. Don't know where this fabled bump steer myth comes from.

I have to agree.

If one jumps through many hoops, can put up with all the parts to change (Know which pieces to Fit), have a OLD School guy that will take the time to Align the car, And you Pay the exttra cost to do these thinks yes they will work fine.

A Dodge truck spindles will work fine on a early Mustang, if you have mechanical skills.

You can use an old mailbox for a hood scoop too, and it will work flawlessly.

Sorry, but spindles are just not that hard to find to justify building a cobbeled up mess.

Which mailbox would you recommend for my cobbled up mess?
