FORD Parts guys?.... Need help checking my research.

[Greg72]

The Mog-9 axles I'm building use an 8-Lug conversion setup that uses Ford disc brakes and rotors.

I was told to locate parts matching this description:

1995-97 F250 Heavy Duty 4WD 3/4-Ton Pickup

I believe all of these trucks would have been disc/drum setups so I'd be looking for the front brake parts, correct? Also, I was told that there might be some variations depending on the GVW of the truck so I was told to select whatever parts had the highest GVW rating. I think this would be either 8600 or 8800Lbs.



The rotor I've found online is this:

Ford OE # YC3Z-1V125-AA (or)
Bendix P/N 145055

This is a 8 on 6.5" lug pattern, 12.953" diameter, 1.185" thick vented rotor.

There are some other choices that look similar but the diameter and thickness is slightly different. Can anyone confirm that this is the correct rotor for the vehicle in question?

Also, for extra credit: Can someone help me locate the correct part number (Ford or Bendix) for the matching caliper that goes with it?

I'd like to start with a stock part, then once I'm sure I have the application correct I can also look at some of the aftermarket offerings from places like EBC Brakes, etc. I'm not sure if the rotor height will change, or if the mounting flange or caliper thicknesses will be different, but if I run into clearance issues I may have to spend more time looking for alternatives.

Ford changed the lug diameter size in 1999, but there might be some overlap between 99 and 98. So that it why they said to stop at 97.
That Bendix number looks right for over 8500GVW.

And as a guess, Motorcraft numbers F7TZ2V121AARM and F7TZ2V120AARM look to be the left and right over 8500 calipers.

NOTE, the calipers in those years came from the factory with plastic pistons. When they were remade, they came back with steel pistons.

The plastic don't rust, but the steel stands up to heat better.

I had a plastic one swell on me once. But Ford ran millions of them without a problem.

You pays your money and you takes your choice......

Thank you!

Am I right in my conclusion that the "over 8500 GVW" calipers use the SuperDuty pads, and the "under 8500" use the regular (presumably smaller?) pads? I seem to see that as the difference when I search.

Also, I see there is an item called the "Caliper Bracket" (uusally around $12 ea).

Based on it's appearance it looks like it might be included on some of the more expensive "Loaded" versions of the calipers. The caliper looks physically larger with this bracket around the perimeter already installed. Am I interpreting this right?


Anyway, I found the following Motorcraft numbers for loaded calipers with SuperDuty pads:

Driver Side: MIBRCLS7RM
http://www.racepages.com/products/?N=4294963368+1616+10328&Ntt=Motorcraft+MIBRCLS7RM&event=search

Passenger Side: MIBRCLS6RM

Am I on the right track here??

Unfortunately you are losing me fast. I have had limited experience with the heavy duty stuff, and what I have had is just replacing stuff.

The caliper, bracket, hardware, are all already on when I get to them, so I don't usually have to worry about part names or numbers for brackets.

However, as I vaguely remember, the caliper is just that. A pair of pistons in a housing.
That part bolts onto the caliper bracket, which holds the pads.
And the whole mess bolts onto the axle tube somehow.

The light or standard duty stuff, the caliper and bracket are all one piece.

If you buy the "fully loaded" setup, I think you will get caliper, bracket, shoes and most of the mounting hardware.

NOTE: Usually when you buy fully loaded, you usually get a choice of pads.

 

[Greg72]

No problem....

When I saw the basic caliper offered, it was like you described. Just a basic 2-piston housing with nothing else included.

The fully loaded caliper has the "perimeter frame" part which I think is the caliper bracket, as well as pads, etc. The problem I have is that this is all custom for my application, so I can't just look at what I already have (I don't have anything yet!). The photos in my installation instructions show a caliper and the perimeter frame part, so I am feeling pretty confident I'm on the right track.

I may just have to go to a local parts store to take a look at this stuff to confirm, or maybe just buy 1 caliper and rotor so I have something to do my mock-ups with...
