My bike is coming up to 100,000 miles and I've never changed the seals in either the master cylinder or the callipers. Clean the pistons as described and that's it. The brakes have never been a problem. I very much doubt you have to change seals in everything. You need to try the easy fixes first, grease pivots etc. The maybe master cylinder. It might be cheaper to change to a Brembo from a Mk1 R1. Much less fade.
