Hi I have a aquired a year end with no brake parts, can anyone help with identifying the year and model. I have it as a 1995 Dana 44. Please note position of the calipar braket on rear of rotor is this correct. Thanks Ron

the 605491 says its a 1995 the -7 I cannot decode. <br/>6 Apr 95 A

 

Its a '95. The rear brakes are all the same that year. Abutment brackets, calipers, rotors and bolts will fix you up. It sure looks pretty under the dust, someone spent some time polishing that.

 

The 12553791 denotes it as a "service assembly" likely/maybe and the caliper attachment I'd say is backward on the LH side as shown. There's not much to question if you rotate the axle one time and you get just less than 3 1/2 rotations of the pinion.

The chassis is/was intended for what?

 

Thanks for the quick reply, I will check the calipar brecket LH vs RH, i thought it was all one piece with the hub housing. The frame is a Collier for 65 roadster. Best Ron

 

Thanks for the response, not clear what an abutment bracket is, but will check it out. Regards Ron

 

Left side - RH would be similar. Image is deceptive, the bolts are through the knuckle, bracket and hub from inside the knuckle.

Mid-year calipers are offset top center to rear aren't they? Maybe the bracket placement was intentional. I'd maybe research that some before just tearing it apart.

 

Since this is for a mid-year it might be interesting to measure the width outer hub flange to outer hub flange to see if the C4 was hung "as is" or if the half-shafts and left/right suspensions were modified for the difference in width mid-year to C4.

 

Hub flange to hub flange is 62 3/8". I called Wilwood brakes today, apparently nothing for the Dana 44. The rear hanging caliper bracket is a mystery so far.

 

The bracket is "no mystery" - it's only the why it's bolted on as it is. The bracket is conventional C4 88+ just like in the image I posted.

Wilwood wouldn't have any references to brakes and rear axle, their packages would be all by type, any C4 88+ big brake package for the rear would be a candidate BUT most offer no e-brake provisions. You could add a smaller caliper for e-brake, that option is available from many.

The bracket should have a casting number on it the LH might be 10052211, it would be between the two empty bracket mounting bores likely on what would be the outer if it were mounted correctly. I believe I can see the casting information on yours. If that casting matches it's just been installed for some reason to it's present position. It's not as installed on a C4.

It seems the entire suspension is mounted as an assembly with no modification for width.

 

The casting number is identical on both brakets 100522112 LRH. Is it possible someone hung the brakets on the rear to hopefully accomadate Wilwood brakes!

 

It's very likely someone just put a bunch of parts together for the suspension units. The bracket LH would be the # I mentioned and the RH would be the # you mention. Is the other side facing forward on the knuckle as it should? I would think regardless of the package you would need opposite brackets to correctly orientate the caliper position. Ron, anything is possible but it would seem unlikely that was a plan.

Baer does a real nice package for the rear with an e-brake and looks to be realistically priced. They do 14" it looks like also.

Thank you for your help, its starting become a little clearer. I will let you know how I make out with the caliper brakets.
Cheers Ron

 

I've got some a few comments.

So this IRS is obviously the second series that utilizes the caliper for the mechanical on the Rotor e-brake.

The Caliper Hub brackets are obviously Clocked incorrectly. The Caliper on all C4's IRS on the front side on the Axle. This is a must for the E-brake cables. Looks like the Caliper Hub Bracket are swapped L to R ??

Yes, Wilwood does sell a C4 (late) IRS Kit,and it includes their "Spot Caliper" for the e-brake, But it uses the thin 0.810 Rotors. And this kit is very expensive.

I already had the C5 / C6 base Front Calipers on my C4 IRS (in my '37 Chevy Coupe build) these requires the wider 1.250 inch rotors, I used Wilwood Rotors,,160-14043-BK & 160-14042-BK . These Wilwood rotors are 12.80 d by 1.25 thick, directional L & R , Slotted, Dimpled, with the internal angled vein cooling slots. a set of four Wilwood's are approx $380, or $99 each. Great price for a Wilwood Rotor. So I used the C5 / C6 Calipers and Wilwood rotors of the IRS.

The new C5 / C6 base, and much larger caliper & pads are a slim $250 a Pair. The C4 to C5 / C6 Bracket adapters are a little of $100. Making such a upgrade at a reasonable price. One will still need to get a pair of the C5 /C6 Calipers mounting brackets, I got a used set 4 for $100.

Braking Capability. I have the Wilwood 4 piston Calipers, Rotors and Hubs on my '56 210 Chevy. She's a bit lighter with the LS1, and We have 2 C5's Corvettes. The stopping power of the C5's are just as good as the high priced Wilwood's on my '56 210. I'm not saying that Wilwood doesn't make great products , they do. But it depends on your budget. I've had to make Panic Braking Stops, and both Calipers are great.

If one uses the early C4 IRS, then the e-brake is a cable, no Spot Calipers are required

The later C4 IRS you'll need to add a Spot Caliper for the e-brake. I have spoken with a Wilwood Engineer and He agreed that their Spot Caliper, and be easily modified (widened for a 1.25 Rotor width.

Personally I wouldn't ever use a driveline E-brake setup, but that's also possible.
