brakepad

Hi there, can anyone explain me why the Berg/KTM rear-brake pads(OEM-parts) are gone within just some hours/days of offroad-riding? :cry: On all of my past Offroad-bikes the rear-brake pads lastet for almost a season? And I´m not talking about pro-racing, I´m just Mr. Average...

Got a -93 FE350 (Yes I know it is old). Brembo brakes. It desperately needs new pads but I just cant get the safety pin out. It rotates and moves slightly from side to side, but not out... What do I do wrong? Is there a friction lock and I should get the C-clamp out? Thanks!
