The Straight Skinny on M/C's

[S Allen]

That other thread was two miles long on the master cylinder. Here are the facts straight from an ASE certified parts person. OEM master cylinders for the Z car are 10mm metric. There was no cut-off from metric to standard. They are all metric. The tubing for the brake lines is a standard 3/16. It is the fittings that are different. A standard thread will go into the metric fitting but it strips the metric threads and does not gaurantee a leak proof system. Rebuilt master cylinders can sometimes be retapped to standard threads because someone has already stripped out the metric threads. If this has been done the rebuilt master cylinder comes with the correct fittings to be placed on the brake lines. There is a 30 to 45% failure rate on rebuilt parts-not just master cylinders. So it is possible that the rebuilt master cylinder some of you have installed had been retapped to standard threads. They do not come from the factory that way. To assume that all rebuilts have been retapped is a disaster waiting to happen. So we are all correct in a sense but never assume any thing. I will add this to the volvo brake conversion write-up. Be safe not sorry.

You are so thourough its amazing! We'll reserve a special place for your Z car no problem, are you going to head home early or stay for the Z Nationals??

If my car is ready by Solvang it will be a GD miracle. We have had a hell of a time with that Tec3 EMS system, the wiring is outragous!! I personally am not counting on it being done after seeing it earlier this week, I guess I will have to wait until Shasta to unveil it.

What bums me more is Corey Hanks has his car all prepped and ready to have the engine swaped and we are waiting to get mine done.

Lou,

I am coming down Friday and leaving Saturday afternoon. I would love to go to the Z Car Nationals but it will not be this year. See you at the show.
