Technical Brake question

These are on my 57 Chevy. Not sure what calipers

 

That looks like the typical GM calipers are required, which makes some sense as they're overwhelmingly the most common calipers in disc conversions.

Camaro ? Of what Gm.

 

Yeah, something like that! I'm not knowledgeable about the variants and am aware of quick takeup versions that seem to cause problems.

I think generically they're known as GM metric calipers.

Quick take up ?

 

A measurement of the distance between the guide pin holes would pin it down. I think the 70s "big" caliper and the newer "metric"calipers are different.

Ignore them, I think! Wierd stuff that involves stepped master cylinder. Way over my pay grade!

Caliper bracket looks like one I used, 70 Chevelle/Monte Carlo.

 

Measure the distance between those threaded pin holes.

They will tell the tale.

 

Ok thanks
