SR brakes for sale

Yes. You need the longer wheel studs too. You'll have to cut a wee snick out of the brake hose retaining eye on the strut, spread it apart, and then close it up after you've added run the S13 hose through it. You'll be able to use the fatory retaining finger clip to hold the S13 hose in place.

Sorry to be a punish with this but id like it to go smooth when i do it,
but if i get the s13 brake hoses when i get the calipers can i use those?

Nope, need new hoses as the S13 calipers are sliding type, therefore need flexhose from strut to caliper as well.
Studs should probably also be replaced with longer ones as the disc now slides over the nub and you lose approx 5mm of length.

Ok so if i get the brackets made up, all i need is the ca rotors and calipers?
I use my hoses and studs?
FYI i have the 1200 disk struts.

That may be an option also. The calipers I had were borrowed, so I wasn't going to do that.

I had to do a very small amount of clearancing when changing from the CA to SR brakes.

It was a few years ago now but from memory I had to grind a small amount of metal off the calipers near where they attach to the caliper mounts.

I had a wee play with an SR20 S13 caliper and my CA18 S13 adapter plate. I can't speak for other peoples adapters, but there is an extra web (or some such, I don't recall exactly) which means that they don't bolt up. They could be made to work, but it would mean spacing the caliper off the adapter plate, and then spacing the rotor off the hub by the same amount.

that'd be more on the money, I've only played with the jap stuff on my cars so

As I understand it, the early 120Y struts and calipers are the same as the 1200 disc ones?
Then the later used the PBR caliper and had different hubs??
