Just a quick but handy one...

Some time ago I had consolidated all the Fiero brake rotor machine specs. Recently I was looking for things to mess with while learning Acrtobat. Now there is a link to a PDF file at the bottom of my brake service article that includes the machining specs for all the OE Fiero and the Grand Am rotors.

(No. this isn't how to do the "upgrade." It's just the specs for cutting them for new pads.)

Ogre, I was just wondering - what brake system do you have on your car? Do you just use the stock setup with new lines/rebuilt calipers?

Thanks

I have a stock system that has had a huge amount of time spent on it. The hand brake is still a bit batty but everything else works the way it is suposed to or better. Stopping power is way better then when I bought the car.

Were there different machining specs for different years? I remember looking in the spec book at the machine shop I got the rotors turned on the 84 SE I was restoring, and I think I saw a few different sets of info, perhaps for another year? I think I remember a separate row for 88's.

I can't imagine why there would be differences between rotors from 84-87...

Hey theogre,
Maybe you can answer a brake ? for me. I am running stock brakes also and have noticed when it rains only they seam to be a little spongy when initially applying then do ok as if to dry the rotors. The pads are about at "half life" and the rotors were all turned upon the last pad replacement. When conditions are dry I don't notice this at all and when the pads were new I didn't notice it in the rain. Is there some thing you could enlighten me on concerning this?

Joe, Yes, all the 84-87's are the same. 88 is differant. 88 is a totally differant system.

Butter, Yes, the pads and rotors could be holding a bit of water. It's not uncommon and some pads are a bit worse than others for it. If you're uncomfortable with them then you can most likely just change the pads.

If they are riveted pads, clean out the rivet holes in the pad material. The stuff in there can help hold water. Many but not all riveted pads have hollow rivets to let out steam.

If they are rivited pads, you may be at or near replacement time. The wear spec is measured from the top of the rivets on riveted pads or from the plate on bonded (Glued) pads.
