I have attack rear sets and the foot brake lever has always worked fine. As in the amount of pressure needed to get the brake light and brake to work was fairly tight. Well tonight it's throw to achieve braking power is way out. I have to push down to the point of my foot being almost straight up and down to get it to make contact. Something is off and I need some help as where it start to troubleshoot. Maybe air is in the system? I don't know. It all looks fine but not sure what I am looking for? Everything it mounted tight and there are no missing bolts that I am aware of.

Just started with the basics. Hooked my hose and bottle up and cracked the bleeder and air bubbles came running through em. Repeated a couple times and the brake felt strong again. The guy I bought it from put aftermarket caps on the reservoirs. Must have let some air in.? All is well for now.
