    I’ve rebuilt my Swiss Hutless Corsa brakes and the seals were in pretty good shape, but I found that they required a light press to reinsert the pistons in the caliper. The bled easily, but the pistons seem to extend but not really retract. I seem to recall the previous owner saying something to that effect, but I’m not familiar with SH designs and he didn’t elaborate… So, what’s the deal? Are they like motorcycle brakes that live near the disc and don’t “retract”, or should I be looking at the caliper to see why the pistons don’t slide “freely”. There are spring-loaded retract bolts, but they must not be overcoming the friction, or the master cylinder doesn’t allow for backflow…

    Help appreciated from those who know… Regards, ~Ted

    Did you use brake lube when you assembled them? Try a bigger spring on the brake pedal.
