i have a sticking front master cylinder (grimeca) on my 1978 3-1/2 sport i have striped and cleaned the master cylinder and front brake calliper (grimeca) and the brake still holds on could the big spring in the master cylinder have lost its strength over the 30 years

had similar problems with my 125H Grimeca, no way to get it going again. I mounted a Brembo moped scooter cilinder and everything solved (and better brake responce!)
