Hello,
I noticed that one of my rotors is looking bad on the 1973 Wagon. Were the same rotors used every year, or are the 71-73 rotors different?
And, while on the subject are there any brake upgrades (I'd like to stay with the four lug) that can be applied from other donor Fords? I have an '88 Turbo Coupe if anything is applicable.
Thanks, Tom
I have been told that the 74 and later Pinto rotors can be turned and used as 'early' rotors (never did it myself).
As far as if 71 to 73 all take the same, I don't know.
Bill
Hummm..., with most places holding to the legal limit rules of turning rotors, I wonder if I can do that??? Thanks, Bill.
Tom
the Rotors are different 71-73 than the 74-80...
To turn the 74-80 rotors down to work in place of the 74-80 would be going way past spec on the rotor surface...
you be better off having the stock rotors surfaced or a used set surface.
if you have to go with the 74-80 rotors you'll have to have the caliper mounts machined and you'll loose the dust shields...I have done this to my 72 with no problems but I would look for a good used rotors to be turned personally.

Nevermind.
Like I said, i never did it myself.
Bill
My argument on this is if you re align the caliper mount you can buy new rotors and pads out of the box using the rotors many times. And you can go to the parts store and do a brake job without doing mods to the brake pads or re machine another rotor.
fabricate and make it simple....or just get some early rotors for cheap and have them surfaced.

Hello Tom,
If you go on a search and LUCK across a NEW rotor for the 1971-73 Pinto then you will pay in the neighborhood of 160.00 "each".
You can buy NEW 74-UP rotors for 50 or less each.
Now... to make them work you WIL need to have the machine shop turn them down to the absolute minimum not allowing for a re-turn.
I have been running this combo on my Purple Turbo 2.0 Pinto for 14 years and never had a problem. This combo is also on my Green Pinto and is working perfectly!
Aditionally you will need to remove .010-.050 from the caliper bracket in only some of the parting line areas of the caliper bracket.
A dremel tool works well...
After turning the rotor there may be some casting areas that do not clear the NOW wider rotor. I did not have to touch the caliper bracket on the green Pinto.
The green Pinto is only using this combo as I am running 16X8 rims upfront and used the 3/8 difference to make sure there was clearance between the tire and fender.
The 74-up rotor is 3/8 thinner than the early rotor so running a front rim with a little more offset is OK.
Stock wheels "UNLESS" running an extreemly wide tire will work just fine.

Interesting... Thanks for the info Pintony.

If you want to run the factory steel wheels, the later rotors could create another problem. The steel rims reference the center hole for location and this hole size increased in the later years (not sure when). I know 71-72 steel wheels will not fit on a 79 rotor due to the 79 rotor center hub being larger than the center hole in the 71-72 rims. You could use the later steel rims or just go to aluminum wheels which usually do not reference the center whole for location.

Great point oldkayaker!!!
I agree. the 71-2-3 wheels will not fit the later74-up Pinto hub.
I love it when 2 minds can work together to a common end!!!
Thanks oldkayaker for your valued in-put.
I give a 1-up to you..

Pintony,
Thanks for the information. A few things I want to make sure about:
1. Can I still use my 71-73 calipers in doing what you said, or do I need the later calipers too? What did you do?
2. You say the rotors (74 and up) are thinner. I assume that since the rotor needs to be turned to the absolute minimum you are not talking about the actual wear surface. Rather, you are saying that the (I would say wheel mounting hub) does not extend out as far as the 71-73 did. Is that assumption correct.
$160 for a new rotor, - Wow. If I don't buy it at a self serve wrecking yard, swapmeet, Ebay (used), or a significant off coupon at the store it doesn't get bought.

Use the stock 71-3 claiper and bracket

I know!!! How rude!!!

I was fortunate to find a set of rotors for my '79 pinto two door through a Carquest dealer. You might try one of those stores. They've come through for me more times than I thought possible.
Since we have this dialog open I have bought a set of 1st generation 82-88 Ranger rotors last summer to try on one of my Pintos" I havent yet to try them on the car but I have mounted one to a stray spindle... I read some where these will swap as well....
We'll see.

Hey 302pinto,
The 1974-UP Pinto rotors are easy to find.
Most likely is that the MII used these same rotors...

The late model rotors are .105" thicker than early model.
Bob
I thought the later model rotors were thicker than the early...I have four pairs of early rotors here and they appear to be a multi piece affair. Which might also be they have some lighter materials in them..I never tried to take them apart or examined them beyond putting them on and taking them off the shelves.

Hey Frank go up and read this post slower.
The friction surface IS thicker on the 74-up rotor, BUT the rotor is thinner if both were lying on a machine bench.

I was at the local Pick A Part (50% off sale) this Saturday (3-15-08). No 8" rear end :(, but I did get a spare tire cover (not cracked) for a whooping $3.58 ;D. Anyway, I went to the other non-sale self serve nearby. There I got the motor mounts for the 2.3T conversion.
At some point it dawned on me that I never checked the '72 Wagon over at the other yard that well, - AND the quoted post above was rattling in my head. I dashed back over there and not only were the rotors there, but they had been removed and were both sitting on the ground! I didn't even have to pull them. I was out the door for $21 for both with the bearings too.
I mic-ed them when I got home and they are .735 on a .685 minimum! They look good too and probably don't need to be turned. I'll check them with a dial indicator when I install them.
I don't know what is more fun, getting deals or talking about them.
Tom
Hey Wittsend,
VERY COOL!!!
No Pinto in any breakers yards around here???
