Hmm, now I have found the manufacture of the calipers I may sand blast them and rebuild them, as I think the will be substantial for the rb25det.
I will also be upgrading the rear drums to disks.
I'm not sure what master cylinder it was running, as it is gone along with the break booster. So they will be new items latter on. I have a lot of work ahead that's for sure.
On another topic I started cutting the floor out today, and nearly have the new pan ready to go in.
