I called JEG'S and talked to a tech there and he said a lot of times new rotors, being made overseas, are milled too thick and this is becoming a common problem!

What to do?

The new pads fit okay on my old rotors, but now my pedal is spungy (mushy) and I'd hate to see what would happen if I had to stop short!

Hmmm... puzzling indeed.

I work at a NAPA store here in Canada where we sell 3 "grades" of brake rotors and several different "grades" of friction material as well. (NAPA has really gotten on the "Good, Better, Best" kick in recent years ... likely due to a lot of competitively priced off-shore crap!

Rotors:
"NAPA United","TRU-STOP", and now a new line called "Brake Right".

Friction:
"NAPA United" (AE = Application Engineered, SS = Safety Stop,CMX = Ceramix, SD = Severe Duty), "TRU-STOP", and possibly "BrakeRight" as well.

When they first introduced these lines we jokingly referered to them as "SureStop", "ShouldStop", and "MightStop"

We stock the "Best" and "Better" lines, and draw the line there.

The "TRU-STOP" line of rotors is a "white box" sort of line intended for the "value-conscious consumer". Most of it is not too bad ... in fact some of it is mfr'd by ITT/Aimco and made in Canada ... very good quality, while others are made in China and packaged in "rice cardboard". My installers say that they have to occasionally put brand new stuff on the brake lathe to "true it up" and then re-install on the car in order to get it out the door. I do understand that this can occur due to improper storage ... rotors need to be stored flat, not on edge, and not in tall piles either.

With this in mind, you'll understand why we drew the line there. We (in our independently-owned associate store) DON'T WANT to attract the type of clientele that would buy anything less. They're the type that will think nothing of spending $20.00 for a dozen beer and $10.00 more for a pack of cigarettes, but whine like hell over spending more than that $30.00 on brake parts! I just don't get it.

Anyway! ... on to the point:
I have not yet heard of any of these off-shore rotors being too thick. I think it's more likely that you have simply been sold the wrong parts ... trust me ... parts people are human, and do make mistakes. One of the most common mistakes are "dyslexic" number reversals (i.e. 88630 instead of 88603)

1.) Check to make sure that the part numbers on your invoice matches the part numbers on the boxes.
2.) Have your supplier check the application again and carefully compare the part numbers to what you have already bought.
3.) Ask if there might be any other optional listings that may have been dismissed. ("Most times it's this one" scenario.)
4.) Insist on buying the "name-brand" parts ... or at least get him/her to bring both types to the counter for comparison. Check them with the naked eye, and then check them with a digital caliper.

Finally, if your brakes have become "spongy" since you had them apart, it is quite likely due to the fact that air has been introduced into the brake system somewhere, perhaps at the bleeder screws or at the master cylinder.

I'll assume that you did use the correct (likely DOT3) and fresh brake fluid while topping up as well?

I'd be more than willing to try to cross-reference the part numbers that you have, and see if I come up with anything different for your application.

HTH,
Don
