it takes at least 4-5 days for it to go completely no brakes. It was all of a sudden, went out there one day and pulled the front brake and it was really easy to pull, which i had rode it the night before and it was pretty tight. I don't think there is air in the system, looks like i'm going to replace the MC. ANATOLPIUPIU, what did you replace exactly?? just the piston?? the whole assembly??
The caliper and master cylinder piston diameters were changed from SP1 to SP2.
Though they look identical externally, they differ internally.
When you order parts, be sure what type you're are selecting.
