I know the cobras calipers are different but does it matter if use V6 or GT (or are they the same)?
hsr said:Shaggy,
The CAD system (PDGS) that this stuff is in doesn't have a .dxf output translator. The best I can do that I think ACAD would accept is IGES. Please confirm is you can take that.
This concept should work on '65-up spindles provided they are the drum brake spindles. If you look at the aftermarket brackets that are sold to put stock disc brakes on original drum brake cars, it's really the same thing. Granted, the '70 spindle looks a little more beefy. I already CAD designed a bracket that would put the SN caliper on the '65 drum spindle. I've been using the 11" rotor, V6 and GT caliper in my study as worst case scenario. Mainly because I run a 15" wheel. Same bracket allows the 13" rotor and Cobra/Bullet caliper to be used (as should be the same with your design).
I personally have the GT-nada style setup on my car ('65). The 2001 GT aluminum PBR twin pot calipers (as the rest of the SN95 calipers) fit to the Granada spindle using brackets I fabricated. The issue with putting 13" rotors on the Granada spindle is lack of the separate hub design the early drum brake cars and the SN cars have.
As far as the centering ring (rotor to hub), there would be some slop as a result of the oversized "clearance" lug stud holes in the rotor as comparred to the stud themselves on the hub. Not a lot, but enough to cause some vibration at high speeds I'm sure. As a side note, Ultrastang started producing and using them for their rear disc brake kit. Just a thought.
Send me an email from the address you want me to forward the data to.
Thanks,
Jeff

a few questions:
How much better do the brakes work with the sn95 calipers?
I if rob these from wrecked car what else should I get besides the Calipers?

When I get this built I’m going to have to do allot of testing. I just don’t feel any slop at all when I have the rotor stationary then put the hub behind it flush with the back or the rotor and try and move it back and forth. If I run into a problem I can always machine one large ring that would go around the hub and between the rotors. It would be relatively simple for my machinist to do that.
You could do this with the 65-66 spindles, but I like the beefiness of the 70-73 spindles. You could also do it with 67-69 drum brake spindles but you would only have 3 bolt holes on the spindle to mount to. That might not be a problem, but I didn’t want to skimp if i didn’t have too. It would be harder in my opinion to do this with the disk brake spindles from 67-73, because you would have to make a bracket like the one I have pictured bellow which would be harder to make. In your set up you use 11" Granada rotors and sn95 calipers correct?
Tell me about it! I just bought a set of drilled and slotted rotors with Cobra calipers (PBR) tooHack said:I'm really chomping at the bit to go back in the machine shop here and cut some metal!
Correct me if I am wrong but I thought the 96-98 Cobras used them too.Mr_siv said:The 99+ calipers are the "pbr" type... which are used on a wide varity of cars, encluding one of the lines of aftermarket baer brakes for our classics.
Billgear said:The Mustang PBR's will take up to a 1.10 rotor, the new PBR's (from the C5 vette, and late Z06) will handle a 1.25 rotor. Plenty of off the shelf coleman rotors in 1.25"
I think a 1.10 rotor will be OK for all but the very very fast road racers.
