Anyone have a list of '65 brake caliper casting #'s and date codes?

I would like to know if I still have the original brake calipers on my car. I'm replacing the calipers due to the bleeders leaking. I tried new bleeders, I tried new bleeders from G.M. for a 1965 Corvette, and most still leak. I searched the posts and found other peaple with the same problem, but no fix. i
If the calipers are factory parts I will have them rebuilt rather than replace them. I'm not sure that a rebuild will address the leaking bleeder problem. My Coupe was built Nov-7-64 and these are the #'s off my calipers, some numbers were hard to read.

Rear drivers side Delco Moraine R1 5473807 1056

Rear pass side Delco Moraine 2 546905 77/

Front drivers side Delco Moraine 5473798 2311

Front pass side Delco Moraine 1D 5452273 1011

calipers are NOT date coded, those extra numbers don`t mean a thing...for 1965 your casting numbers should all start with #546

Thanks: looks like only one may be orginal. I guess I'll go for a set of over the counter '65 to '82 service replacement calipers. Dave

It may be a #546 but it`s doubtful it`s an original.....Lonestar can fix you up with a sleeved set of #546 calipers.....their price is right but the shipping and return shipping of the cores will kill you

redetracr: Where is Lonestar located do you have phone # or web site? Did you have to wait long to get yours? I need to get the car back on the road before the snow starts to fly, down to 0 C the last couple of nights. Are the front & rear calipers the same? I would like to know if the set on the car are a matched set. What is the difference between first generation caliper and the newer replacements?

Lonestar won't deal with individuals. They will do your work only through one of their dealers.

I had my original '65 brake calipers rebuilt through Vette Brakes in Florida. They did a nice job. They converted these first series calipers to second series. You can't tell by looking at them from the outside, but it should improve performance/leaks.

I realize this is an old post but I also have replacement caliper # 5473807 and rear rubber brake lines will not fit. This is for a 68 did they change to larger brake lines because fittings in caliper are much smaller. Thanks Phil

To start with, 5473807 is a rear caliper, and the rear hoses do not connect directly to the caliper. The rear hoses are installed at the pivot point of the trailing arm. The hose connects to a short steel line, that runs the length of the trailing arm, and the steel line then attaches to the caliper.

As an FYI, the 5473807 is a left rear 73-82 casting. The correct casting numbers for a 68 are 5452270 right front, 5452273 left front, 5452281 left rear and 5452284 right rear. It doesn't make any difference though, as all 65-82 calipers are interchangeable, and all take the same size hose (front) and steel line (rear).

Thank you for the info. looking at rest of my brake line kit it now makes perfect sense. Thanks again Phil
