I managed (in a pinch) to fit a VW screw. The only diff was that it was slightly longer, but the taper and thread was a perfect match. I took a good screw from the other caliper to a VW shop and they "eyeball" matched it. | ||

Great idea! I've done this many times. Cop-a-slip is my favorite. This is the reason many mechanics say they won't do the brakes on a road car without a oxy-acetylene torch. BTW, I torque bleed screws with torque wrench, too. 13 ft-lb for 348 and newer Ferraris. | ||

Go to your local M-benz dealer and say you have a 1992 M-Benz 190 2.6. The calipers on the cars are ATE. The bleeder screw should be the same. | ||

Yes indeed, Porsche uses the same bleeder valves on some of their 911's. When mine went bad, I took out a good one and went shopping at my friend's Porsche dealership...came up with the correct bleeder valve and no problems since then...some ten years ago. | ||

Mike, Metric thread can be a little ambiguous at the best of times - When some one quotes for example an M8 Thread; it is usually taken as "metric course". On a M8 Bolt (metric course) the pitch of the thread would be at a spacing of 1.25mm (rather than Threads per inch in the UNC, BSW etc�. systems) Most people these days adapt the system of adding the letter "p" after the second set of figures. M8 x 1.25p (8mm outside diameter and 1.25mm pitch spacing between each thread) So the M7 x 1 is 7mm O/D with a 1mm pitch. 1mm pitch is very easy to measure with a ruler, as the millimetre markings will line up perfectly with the tops of the threads (Can get even more confusing when you start talking about a 3-start thread with a 1mm pitch and a 3mm lead!) I would personally take the rears off, as you would hate for the same thing to happen again! � At least you would know now that they have broke rather than just before a track session!! Also thinking out loud maybe a little copper grease on the threads to stop them from corroding them selves into the callipers? � Someone please correct me if this is not a good idea. Paul | ||

Paul, Thanks very much for the info... When I said shank size, I may have been confusing it with another measurement, as I haven't actually measures the OD (outer diameter, right?) of the threads... The SB7100 is listed as having Metric Threads, "7mm X 1.0." I'm not really sure how to interpret this... If I had to guess, I'd say that the diameter of the shank is 7mm, the outer diameter of the threads is 8mm, and the nut size is 9mm... Thanks for your help very much... Does anybody have the specs for the rears, or should I pull one of them, too? | ||

Mike, Just thought - you said shank size of 7mm - do you mean the O/D of the thread? - If so that rules out my last post!! Paul | ||

Was bleeding my brakes tonight, prepping for tomorrow's autocross. When turning my left front bleeder out, it just snapped right off, at the surface of the caliper. Not a very pleasant thing. In any case, I need to find a replacement screw; autozone and the like have nothing like it. These are ATE calipers. There is no ferrari part number for the bleeder screw. There are references to Ferrari 308s using the same or similar calipers as Porche 911s and/or 914s, but nobody seems sure, and this seems to apply to either front or rear calipers (there's contradicting information here), and even then there's question about the calipers being identical or sharing parts. In any case, I'm totally hosed--one little bleeder screw is going to put me out of commission for a week.  Does anybody know the sizes of the bleeder screws? I've pulled the good front one, and I know its size. I'm planning on replacing all bleeder screws with "Speed Bleeders." Check out: http://www.speedbleeder.com/size.htm So far, my thinking is that the front ones match the SB7100. These are 7mm shank, 9mm nut size, approx 35mm overall length. I'm not sure about the rear ones--they're a 7mm nut size, which might suggest an SB6100... Does anybody have any experiences with these brake bleeder screws? Thanks, --Mike |
