V-Calipers are Here!, Rear Calipers and Kits for Vented Rotors Options

[Eric_Shea]

NEW V-CALIPERS ARE HERE!

The V-Caliper was designed to allow teeners the use of a vented rear rotor on their 4 or 5 lug cars (If you’re going to remain 4-lug you’ll need to have your rotors drilled for the 4 x130mm pattern). These are sold as completed calipers on an exchange basis and have all the features of our regular caliper rebuild service.

Here's what you get:

* Disassemble caliper
* Bead blast caliper to bare metal
* Replate with factory silver zinc plating.
* Hone the cylinders
* Polish Pistons
* Install piston and adjuster screw rebuild kits
* Lube and reassemble the caliper
* Install caliper spacers
* Special rotor spacer drilled for 4 or 5 lug applications
* Longer brake pad pins.

Pricing is $455.00 per pair plus core and shipping. I only sell these in pairs (obviously). Shipping is a flat $9.30 for Priority Mail to anywhere in the continental United States. For international orders you can still use the USPS link. Boxed weight is 17lbs. You can calculate postage from 84092 using this site USPS Shipping Calculator

This application will now use the standard 1970-1977 vented rear rotor. The vented rotor will need 4mm turned off the outside edge (8mm total) to work with the V-Caliper. We can supply new Zimmerman rotors for $75.00 each plus shipping.

The grinding was done at one of the adjuster access hole tubes.

No clue (IMG:style_emoticons/default/confused24.gif)

Nothing in that kit would require that grinding. Grinding was needed because of those washers that were added. Now... I've seen access tubes welded in high before but, the fact is, from the mating surface of the caliper ears and the trailing arm back toward the trailing arm, this is nothing but a stock caliper.

The spacers are correctly under the rotor yet still required a bunch of washers between the caliper and ear mount. Could it have the wrong type of rotor (thickness)?

No. Wrong rotor thickness would probably not fit in the gap. There should be only about 2mm per side gap. More like a later model hub offset or 944 rotors. I don't know how far the washers are pushing the caliper back but, seeing as how you have clearance issues, I would say a LOT.

I would check two things:

1. Hub offset vs. a 914 hub. I can almost see it in that picture in the link. Those hubs are laying very flat but... that's a picture and I may be reading into it. Are they the later hubs with centering rings? I can't seem to make that out in the picture. If so, this is your problem. You'll find some threads here about 5mm spacers that have been manufactured to make them work. This would be my "first" guess. Later hubs need spacers to bring them out... otherwise you will have the problem you have.

2. If the hubs are correct I would then look at the rotors. Are we sure they are 911 rotors? They could be 944 rotors. They look identical to 911 rotors but are shallower making it necessary to space the rotor out and the caliper back.

Your opportunity (not a problem) is hiding in one of those two areas... (IMG:style_emoticons/default/wink.gif)
