1969 Z28 Camaro front brake calipers 633 casting number Left or Right?
« on: January 01, 2011, 08:50:06 PM »
Gentlemen i have a pair of used original 1969 Z28 Front calipers. The casting numbers on both are 5483633 but are not identified as Left or Right on the castings. Is this normal, did these factory calipers have a L for Left or R for Right cast into them. Or am i alright here with no identifications at all?

Usually do have an L or an R..
Are the bleeders in the same positions or opposite?

If you set both calipers on the floor with the piston facing in the same direction, the bleeders are  in the opposite direction.

Steve,
When installing the calipers on the rotor, the piston side faces towards the engine on both sides. When doing this the bleeders are opposite of each other. Hope this helps explain this. To me these will work without a L or R Letter cast.  Am i right or not?

If the installed calipers have the bleeders on the bottom, you will not be able to bleed the brakes properly.

After finding some pics on ebay i do have a left and right caliper, and they both are 633 cast numbers. The bleeders are on top. Also both are 69 date codes. For some strange reason both of these calipers have no L or R for identifications. It doesnt appear these letters were ground off. Are these some special ones, i dont know. But they are a left and right. Any more input is greatlly appreciated. Rally
