As much as I hate to start a new thread, I have been searching for hours now... I figured it would have been covered before but I sure can't find it.
Car - 88 Fiero 2.5 Auto - 100% factory stock.
Problem - Leaking rear seal on brake master cylinder.
I purchased a reman from AZ (P/N - M2357)
A knowledgeable Fiero friend told me to watch for them selling me one with the wrong bore size.
So I am verifying... maybe...
From the little I was able to find here on PFF in threads about the differences between the Fiero and S-10 masters, the Fiero master has a 0.944" bore diameter. That equates to 24mm.
The spec sheet AZ printed out for me says that their master has a 1.414" bore. So right off the bat, I think I have the wrong master.
However, I went to Advance as well as O'Reilly's and any master they brought up said 24mm/36mm.
So I'm on a hunt for what the correct bore size should be.
I suspect that the chamber for the front brakes is 24mm and the rear is 36mm. Dose anyone have the no longer available shop manual? Perhaps it would say in there. I lost my downloaded version with my last hard drive failure.
Either way I figure I'll be taking the old one apart and comparing it to the new one. I just want to try to make sure I get the right part before I tear the car apart again.
