I was getting ready to take the caliper off the PB, and on the end of the pins it floats on was a large 'L'. I got to worrying, is this thing left-handed thread on the driver's side? I've never seen a GM product whose disc calipers used an outlaw thread. Nor had the guy at the parts house when I ran up there to pick up a 3/8ths hex socket for the pins. So I popped them loose, righthanded as I had figured. Haven't looked at the passenger side one - that caliper works - but I bet they have an 'L' on them as well, which is confusing.

So a question for some of you old GM employee types. Did GM or GM-Moraine perhaps have an outfit called Lamson Fasteners make the pins? They had a foundry in Brimingspam among other places, and made some special hardened parts for Continental Gin Company, for whom I used to build cotton gins as a kid. It's silly - but I'd like to know why the pins have an 'L' stamped in them. Lamson was bad for stamping Ls into everything they provided.

The difference is the hose attachment and air bleed screw, if you turn your L caliper around 180 degrees you will see what I mean Cool

Yes, they're mirror images. But what's the difference in the pins? Other than the letters?

I can not say for the RV since I have not done a brake job on it yet, but I have never seen any differences between L/R pins on any car.

But I did check the parts manual just to be on the safe side and the only differences between L/R side is the caliper all other parts are the same.

I never saw a difference in pins either.As to hoses, all the parts places list different part numbers left and right.. The only difference I can think of is the retainer clips would be reversed from side to side.
