I was doing maintenance on my Blaster, oil n adjustments. I took it for a ride and its running great I rarely use the brakes mostly gear down and maybe tap on the rear brake every know and again but I was testing everything when I use the front brake I hear a loud "KNOCK" its only when I use the front brake and it is every time! I inspected and adjusted the line just a little bit bc the brakes are nice and reactive. Has anyone had this issue? how can I fix it? my main concern is I'm doing some kind of damage to the system and will eventually have no brakes. Thanx in advance for the help! =)
