'72 brake rotor Q

[tat2dphreak]

ok, here's the situation...

I pulled the new brake rotors off of my white car(they'd been installed for about 1 year with very few miles) to put on my red car...

problem is, now the brake calipers won't straddle the rotor when installed... it looks like the rotor should be about 1/16"-1/8" closer to the brake caliper mount...

I can't figure out why... the inner bearing goes all the way to the point on the splindle that it should go, and its "race" is all the way in... these rotors fit perfect on my other '72...

here's my question, did they change the rotors at some point during the '72 run? if so, what point? and does that mean I need to buy new front rotors? the ones from '73+?

thanks!

tat2d:

Looked this up in some old info I have. It seems that the rotors did change in mid-72. If your chassis serial number is higher than 4722919032, you need the 73 thru 76 rotor, caliper, etc.

Hope this helps.

yea, I found that too last night and yes, my vin is 4722920XXX

I'm a little frustrated at that, since these are VERY new (< 200 miles on them) and I didn't want to buy a new set (AGAIN!)

I had remembered someone telling me that they changed some things in the front in mid-'72... but didn't know what...

c'est la vie... well, SOMEONE is getting new rotors and wheel bearings with the roller! at least I don't have to buy a new master cylinder too
