In a guide for adjusting Avid BB7 mechanical road disc brakes, it said:
Only use the barrel adjuster at the brake lever to adjust for cable slack. For lever throw, use the outboard adjustment knob. For brake pad wear adjustment, use both the inboard AND outboard knobs.
What is lever throw?
What is cable slack?
Which of these should I use to dictate how far I have to pull the levers to come to a dead stop?
For the BB7, it is recommended to have the inner (wheel-facing) pad about 2 times further from the rotor than the outer pad.
