Norge front brake lock-up

Hi Folks,
Just over a year ago I bought a 2015 Norge which had very low mileage, it having been a demo bike. All was well until recently my front brakes locked up. Luckily I didn't need a high level of skill to control the situation as it happened when I reversed down my driveway and applied the front brakes. I only noticed it when I tried to go to work the following morning and the bike wouldn't move. Opening the bleed screws didn't release the wheel so, once I got the time, off came the calipers. I found that the pistons were all tight so out they came and new seals were ordered. The cylinders were in perfect condition and the pistons only had a deposit of black stuff in a ring around some of them, the result of the low mileage and the seals sticking in places I guess. They cleaned up very well with a commutator cleaner and I had no qualms about using them again. I bought the seals from a highly reputable source but when everything was going back together the smaller diameter pistons were very difficult to slide into the pistons while the larger ones went in as I would expect. The brakes seem to be working correctly but I am a little uneasy about those tight pistons. I don't like it when things look like they should be right but are just not quite so. Am I missing some fundamental here? I emailed Brembo about it and they might yet reply, but perhaps an experienced hand on here might enlighten me.
Thanks
Brian
 
If the caliper is working correctly you are probably OK. Some of these Brembo calipers are difficult to rebuild which is why you no longer can get rebuild kits from Guzzi. If you want complete peace of mind, replace the entire caliper.

Thanks for the reply, John. I was out on it today and the brakes worked fine. I'll go lightly for a while and see how they are. I came to a stop today with smoke billowing up from my right hand exhaust header, so my brakes are taking a back seat till I find out what's spilling oil on there. I'm not loosing much oil so hopefully it's just a breather hose. So it's fairing off next. Never a dull moment.
