Thanks for your reply, Raku! I think that you're in the correct way... the brake might be enough, but now has any kind of problem.

My brake-disk is the original from 1990! I think that is in good state, the motorbike has only 30.000 kilometers, but I'm going to check it.

Also, in a few weeks I'm going to change my fork with a new one (from 2007 GS500), progressive springs and oil and i'm sure that this change will improve the brake system. I'm planning to change in this moment the steering head bearings (All Balls) and buy a repair kit from Suzuki original parts. I think that my bike will change like night and day!
