Can anyone help identify these ATE calipers?
 

I had the brakes upgraded on my 77 911S several years ago. The shop is no longer in business, and I've managed to lose the paperwork on the conversion. It's time for new pads, and I don't remember what car they came off of...I believe it was either a 5 or 7 series BMW, but...

The fronts are 4 piston ATE's:
right side outer - "BMW 59R"
right side inner - "127R"

left side outer - "7R"
left side inner - "148R"

Dual hard lines into the caliper, 3 bleed valves

The rear are 2 piston ATE's:
right side outer - "7R"
right side inner - ???? (couldn't make it out)

left side outer - "145F" (with a "2" underneath the F)
left side inner - "54R" (then 3 symbols, can't make them out)

Single hard line into the caliper, single bleed valves

I pulled the pads, and there are no makings on the backside. I can take some pictures of them (calipers/pads), if it will help. The calipers fit the original mounting points (Bilstein struts), without adaptors.

Hello

1.) Those should be ATE calipers ( Alfred TEves )
2.) The cast numbers are useless and only identifying the production inerta.

Take the brake pad and visit you local dealer, he then can messure and compare the pad and find out what it was. 3 bleeding valves are normaly Ferarri or Volvo 4 piston calipers maybe you have some rare Maserati units ?

Could be BMW as well.

Early-to-Mid-'70s BMW Bavaria's had four-pistom Ate front calipers, and I vaguely remember them having two hard lines to each caliper.

Someone from another post hinted that a 1977 BMW 320i uses a 4-piston cast iron ATE with the early, 3.0" mounting bolt pattern. Could these be it?
