I want O-ring stainless sleeved.  Where do I get them?  I guess I need brake hoses(2) & pads.   Should I do all 4?  Can I just get away w/ 2.  Rear M.C. Is new.

I have heard rebuilding with O-rings not enough.

Thanks for help & suggestions

I am sure that someone has idea’s

How often do you drive your car?

Nothing wrong with the lip seals.  Just go out and pump the brakes once a week.  All the vendors have replacement calipers.

Check in with Bair's Corvettes, our forever fantastic sponsor.

Is that why Chevrolet discontinued using lip seals all together?  I know I will just rebuild them with O-ring calipers

They discontinued lip seals on the fixed mounted C3 calipers? When?

I wasn't aware that they did. 

Personally I'm not sure that O-rings are a good idea because w/ lip seals, the more pressure, the better they seal.  Whereas w/ O-rings, the more pressure, the more likely they will leak.

Good info on C3 caliper seals.

Greetings to anyone who may be attentive. So...Are lip seals available in SS lined calipers?  MY reason for wanting SS is rusty corrosion. The seal is not the reason. I.M.H.O. the least amount of residue from rust or corrosion is what keeps the contact in the bore, and does not allow seal to pass fluid by, and be messy on the outside. I agree with lip seals, but cast iron seems to cause leaks. Help me better understand. Thanks

Stainless-Steel lined calipers will not allow rust to form on the surface that the lip seals will contact and that will prevent any leakage.

I know that others will probably disagree with me on this but when I replaced my front calipers with Stainless-Steel lined ones and honed the rear calipers, I went to silicon-based brake fluid. The rears never leaked and I attribute that to the fact that silicon brake fluid is not hygroscopic.  YMMV  😉
