For sale is a pair of rare 914-6 calipers completely restored to their preeminent glory.

For those looking these days, it was probably six months before I stumbled upon these. They have become rarer than hens teeth as of late. What you get with a 914-6 caliper is:

* A slightly larger caliper that bolts on to any standard 914 rear arm.
* A larger 911 rear pad size.
* A pair of larger 38mm pistons (again, same as the 911 rear through 1983).
* A caliper that will allow you to run a larger front caliper and retain proper brake bias.
* A caliper that can easily be spaced to become the uber, uber rare 914-6/GT caliper... all with factory parts (inquire within).
* A caliper that uses stock handbrake cables.
* A true solution for those who want a little more brake in their 914.

As mentioned above, these have become quite rare lately. Part of the reason is the Ferrari rear caliper market has gone through the roof as well, dragging this caliper along with it. If you've been wanting a pair for your project or, or your original 6 calipers have gone missing... these are for you. Asking $1,595.00 plus $10.50 shipping to U.S. destinations. $26.55 shipping to Canad and Mexico. $43.23 to Europe and Asia.

A month ago, I would have grabbed these in a heartbeat. Eric's got all of my new brakes at his shop right now.

If you've been looking for them, you know that this is a good price. Don't let this opportunity pass you by...

Hey, those look just like mine only a little different....




Mine seem to be a little wider. Seriously, Eric is the man when it comes to brakes. I love looking at these and will hate to bolt them up when the times comes but bolt them up I will. I am pleased to have these beautiful parts for my car.

That's real gold, right?

Posted by: sean_v8_914 Nov 17 2011, 10:35 AM

I will have a set in my hands soon, right? when it happens, I will close the shop, draw the curtains and have a private moment with them alone. then I will put them on another man's car, take pictures and dream of calipers gone away

Posted by: Eric_Shea Nov 17 2011, 12:27 PM

Soon is a relative time frame . They are at the machine shop now getting the bleeder mod. done (Ferrari calipers). When they get back they get plating and will be lovingly assembled by my tender falanges.

Posted by: Eric_Shea Nov 17 2011, 12:33 PM

Yes. Which makes them entirely too heavy for your car. Might I suggest something a little lighter and more cost effective?



They're "all-the-rave" in Canada right now.

If you've been wanting to do this upgrade then you should totally jump on this deal!

sean_v8_914 I can make that 'fantasy' happen and might if I can't get my project rolling soon...just be gentle with them and clean 'em off before they go on

Hey Eric,

I got a set of 914-6 calipers waiting to come off my six. How much to rebuild them to 914-6 Gt specs? I have a set of rear 911 M calipers that the hardware could be used from. Or I may just sell them and upgrade to Boxster rear calipers.

Posted by: stugray Nov 17 2011, 02:02 PM

Eric,

Very interesting.....

When I purchased my 914, I got a box of calipers.
One pair of fronts look as nice as that set, but have 38mm pistons in them.

I assumed that they were from a 911 and the PO was going to upgrade.
Perhaps I was wrong.....
Any distinguishing numbers or ways to identify them as 911 or 914-6?
I will send pictures once i get home.

I sent the pics to you once before, but the quality was poor.

After seeing this picture I outfitted all four corners with this system. I ended up crashing at the first stop and will be having my lawyers contact you ASAP

Posted by: ewdysar Nov 17 2011, 05:51 PM

Apparently you did not adjust the pad clearances correctly, so I would have to say that this was an installation/operator error. Given that, I don't think that Mr Shea is liable.....

It's not Mr Shea's fault you can't squeeze hard enough.

If your loose calipers have 38mm pistons, they are most likely 911 rears, probably M calipers.

The stock 914 calipers had 42mm pistons in the front and 33mm pistons in the back. The piston areas were 1385 sq mm and 855 sq mm respectively. This gave the brakes a natural 61/39 bias towards the front brakes, that's 56% more power to the fronts than the backs.

The 914/6 and 911s had 48mm fronts and 38mm backs with areas of 1809 sq mm and 1134 sq mm. That worked out to a natural 61/39 bias towards the front brakes, weird huh.

If you use 48mm fronts (911) with 33mm backs (stock 914) your brake bias shifts to 68/32 which puts 112% more stopping power to the fronts compared to the backs. That makes the rears largely ineffective. This matches what 914 owners have observed ever since they started upgrading their brakes.

So if you want to use the better 911 48mm front brakes, your best bet is to find 38mm rears. If you want to retain your stock e-brake setup, that narrows your choices to 914-6 (non-vented) or 914-6GT (vented). You can also do slight modifications to Ferrari 308 rears (also vented) and they'll work the same. The regular 914-6 calipers can be spaced for vented rotors

The problem is that all of these 38mm rear calipers with cable e-brakes are almost impossible to find. But wait, there is beautifully restored set available right now, right in this thread.

So if you're thinking about 911 fronts, well balanced brakes and keeping your 914 style e-brake, now is your chance. These opportunities only come up a couple of times a year.

Act now... supplies are limted. If you call our 800 number in the next hour Eric will include two sham-wows.

You're about 3 years too late, Grasshopper. I've been running those on all 4 corners for 3 years now.

Posted by: Eric_Shea Nov 17 2011, 07:50 PM

Damn Eric... You're hired!

Posted by: 396 Nov 17 2011, 10:29 PM

Great question...whats the 'cost' to redo a set of -6 rears?

Congrats,

Posted by: stugray Nov 22 2011, 08:37 PM

Eric,

If you have the time, please tell me what these are:



The pistons are definitely larger than stock 914.

And other pics, from here:

http://s366.photobucket.com/albums/oo101/stuartjgray/914_brakes/

Any chance these are 914-6s, or just 911s?

Stu

Posted by: Eric_Shea Nov 22 2011, 08:52 PM

Those are early 914 front calipers with 42mm pistons. Not good...

One appears to have been rebuilt by Rons buddies at A1 Cardone hence the dual bleeder arrangement.

Posted by: stugray Nov 23 2011, 02:28 PM

worth anything?

I was about to use them until I measured the pistons and didnt want to mess with my balance.

Stu

Posted by: rudedude Nov 23 2011, 05:09 PM

Eric,

What do you mean by "not good" for the early calipers?

Jule

Posted by: SLITS Nov 25 2011, 10:17 AM

Speaking for Moroni Boy ... he is probably commenting on the quality of rebuilding done by A1/Cardone and other production rebuilders.

He could also be commenting on the fact that the early calipers are different from the later fronts and are specific in their fitment.

I wasn't aware that A1/Cardone drilled the fronts for the extra bleeder, but am aware they did drill the rears for the second bleeder (converting single bleeder to dual bleeder).

Posted by: Eric_Shea Nov 25 2011, 02:34 PM

Not really...



As Stu mentions above... it messes with your bias. 911's didn't have the 42mm piston in the rear until 1984 and that was the first 911 ever to have a pressure regulator to prevent rear lock up.

For a 914 with stock brakes 42mm front and 33mm rear makes the most sense. If you want them to be better, get really good pads and bed them properly.

For a 914-6 or a modified brake system stick with 48mm front and 38mm rear or, in the case of 951 calipers etc., go with the complete system that Porsche developed and work on a handbrake solution.

That said, Stu's solution (aside from finding 914-6 rear calipers) is to get a 911 rear caliper and remove the spacer (or use with the spacer and go vented rotors). The 911 rear calipers are cast off the same mold as those (early 914 fronts) but they have the proper 38mm pistons. Vented rotors add weight were they are not needed in 99% of the cases.
