|November 11, 2010 - Wow, the new caliper brackets sure are shiny!|
I've never seen a brand new set before, and I'm pretty sure new Miatas don't have that sheen to them. You can see the extra height in the new one, that gives clearance for the larger brake rotors. Usually people source these off a junk Miata, but we're all out at Flyin' Miata and it's not clear when we're going to see more. So I took the easy way out and just ordered these shiny ones. I did have to transfer two rubber seals from each old bracket though.
I did find out why the master cylinder has the F and R ports. There are two pistons inside, and the one closest to the pushrod pressurizes before the second one starts to move. So the first piston should be used on the front brakes. Interesting!
