Im not too happy with my new 6" avid mechanicals. The back one is working fine, but the front one is so-so. My old tektro V's could at least let me stoppie, the avid front brake cant stop me without help from the rear brake. Ive adjusted the slack and the rotor position between the pads, cleaned then with isopropyl rubbing alcohol, and done everything i can. The closest bike mechanic that i trust is an hour drive away, and i would like to fix it myself anyway. Can anyone give me tips or at least tell me why its not working?
