I found the source of my brake problems...
The inner pads were munching on the rotor. The inner rotor now looks like the rings of Saturn. I am replacing the full brake system (minus booster and resoviour..sp?) The online parts description list parts with and without performance package. I assume they mean 1LE..correct? I only had this car a few months... how would I know if they are performance package or not??
92 z28 5.7...seems all stock. Please help before I buy online(rockauto.com).
Thanks

 

measure.

1le has 12" rotors

everything else has 10.5" rotors

 

When they ask about the performance package, they are refering to the 1LE package.

 

many thanks... this helps a great deal.
:yourock:

 

Dewey, I though 1LE's were like 11'' or so? LOL I guess I could go in the garage and find out, nevermind.

 

The 1LE's were supposed to be 11-7/8" in the front and 12" in the rear according to the Hollander interchange a few updates back. I know that they measure closer to 12" though.

 

I have completed my brake rebuild, nothing fancy, just new Raybestos rotors, hoses, pads, Federal Mogul bearings, and Timken seals.. Oh yah rebuilt calipers.

BEARINGS!! Big problem. I had to go to three stores before I could find the correct outside bearing. All the look ups showed V3 or A3. In fact, the correct size was A12(Federal Mogul). Thanks to a guy at O'Riley's, it took only a few minutes afterwards to finish the job.
Hope this help if you looking to replace you bearings.

 

hey i dont want to take over the thread but it seems the question was answered..............but i was wondering if i bought 1LE caplipers could i throw those on my stock 1991 z28 rotors? if not what would i need to get these things to fit, just new rotors or what?

 

to run the 1le calipers you would have to do a complete conversion. the carriers are different, requiring spindle mods, etc.
