Just for confidence sake.... I have toyota 4x4 calipers on my 72 240Z with

braided stainless flexible lines and stock booster + Master brake cylinder....

works great

Not just a Z - zdisease

Since this seems to be the most active thread, I have a couple questions that I can't find answers to:

With the Toyota calipers, does the larger piston go on the top side (trailing edge of the disk), or the bottom? I'm guessing trailing edge will keep the chatter to a minimum.

Same question for the little W shaped clips. These go on the lower edge (for the same reason)? It looks like they clip around the pad retaining clip and then into the holes in the middle of pad.

Thanks in advance!

The bleeder needs to be at the top, regardless of piston size preferences. Otherwise you'll never get the air bled out.
