Just wondering if anybody has anything good OR bad about the Cardone remans on these?

Looks like it's Cardone 18-4491 (right) and 18-4492 (left). I'm surprised they're available as it was a 2 year only item. I wonder if the 69/70 single piston calipers (and their pertinent caliper brackets) can be used instead.

I have heard that the 4-piston early disc brakes can be troublesome unless you get the bores sleeved properly in stainless steel by a company that known as "Vette Brakes". Pistons can get cocked in the bores and stick, plus they can leak. Sleeving them is supposed to cure those tendencies. Another thing about the 4-piston discs is that the calipers are fixed and are intolerant of rotor run-out. Later single piston floating caliper brakes are cheaper yet way more forgiving in the real world. If you are going to retain the 4-piston design, you cannot cheap out.
I don't know anything one way or the other about Cardone. Find out if they have stainless sleeves. If they don't, keep looking.

As I understand it.....the single piston calipers MAY have found their way onto some late 68's...
Just got off the phone with Cardone tech....and the said they ARE stainless sleeved....
I pulled the trigger....and have a set on the way.....
Saw the thread on fitting the later rotors....which will be helpful...if needed...

There were two problems with the 4 piston calipers, the first was corrosion, but the other was the location of the piston seal.
The 4 piston seal was located on the piston, not inside the caliper bore like the single piston style.
With the seal on the piston, any run out could cause air to enter the caliper past the seal with the resulting spongy brakes.
As mentioned, check carefully for any rotor run out.
Thanks

Yeah when I bought my calipers fro the 'Chief I had to replace 2 of the "o" rings but after that I never had an issue with them and I had 4 of 'em on my car. The car stopped better than my new Ram!! Plus they looked neat behind the Torque Thrust D's I had on.
