Eric,

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

(IMG:http://www.914world.com/bbs2/uploads_offsite/i366.photobucket.com-10819-1322015831.1.jpg)

The pistons are definitely larger than stock 914.

And other pics, from here:

http://s366.photobucket.com/albums/oo101/s...ray/914_brakes/

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

Those are early 914 front calipers with 42mm pistons. Not good... (IMG:style_emoticons/default/sad.gif)

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

Eric,

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

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).

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.
