That is the kind of situation where I used to carry some spares with me and then run the heat checked rotor until it was much closer to cracking. A lot of times I found I could get a day or two out of something like that. However, if you don't have the spare you know it won't last, just the way things are.

FWIW I'd keep running them but I always carry spare pads and rotors to the track. I use the spares for street pads so I don't have to mess with bedding them normally when going from street to track. If I need them at the track though I can just throw them on and bed the track pads.

C3 74. Rear brakes will not bleed
I recently purchased a 74 C3 that has sat for 10 years. Pedal went straight to the floor. Pulled all four wheels. Noticed front left caliper was leaking. Removed and had both front calipers rebuilt. New brake lines and had rotors turned. Rear brakes seemed fine. Bled brakes the conventional way with wife pressing the pedals...back brakes would not bleed..I went to front brakes and they bled fine. Have about 2/3 pedal. Reopened rear bleeder valves but still no fluid.. Had wife push pedal as hard as she could but no juice..... Any help would be useful.. Headed to garage now to remove rear brake lines from calipers to see is I have fluid to them. Noticed 2 bleeders on rear brakes..Any sequence to bleeding them? HELP
Thanks. SP

The fronts didn't have two bleeders? I thought all stock C2/C3 calipers had two bleeders but the last time I worked on a C3 was over 30 years ago. I can't remember the GM instructions for bleeding the C3 brakes but their instruction for the newer C6 and C7 fixed calipers is to bleed the inner first. However, some aftermarket companies like Wilwood say to do the outer first. I have been using the outer sequence on my stock C6Z and C7Z brakes with no issues.
Hopefully, you get your fluid problem resolved. Were the front calipers stainless steel lined? I wouldn't trust any caliper that hasn't at least had a stainless steel lining installed. Of course you can also get into the discussion of lip seal vs O ring seal. The stock lip seal is better from a brake performance stand point whereas the O ring is more durable. If you are going to use the car for some autocross or track events the lip seal would probably work better.

New rear rotors with a light bedding... what’s happening with the 2 different surfaces?
Maybe some taper in the pads and not making full contact with rotor? Same on both sides.

For a while I ran without the (stainless steel spring steel) hardware and did not even realize it (rears).

Thanks, this makes sense. Maybe worn spring plate. I also have 1 backing plate spacer stacked on the inside and not outside... maybe this has an effect.
