Cleaning, refurbishing, replacing, can only be done well once things are taken apart IMHO. It also continues the discovery process. Best to know exactly what you have before you venture down the road. Critical tools include a sharpie and a box of ziploc bags. However, the kit also must include your favorite penetrant, and your favorite degreaser (I like purple power). I was actually pleased by the state of the frame where the brake cylinder is mounted, as I have seen compromised frames in this area due to the corrosive nature of brake fluid. The rear subframe gets cleaned up and painted.
