yes dont overtighten as I cracked mine too. Wouldnt say it was oooooverly tight, but when i had a fall and the handlebars smacked the concrete, i think the vibrating caused the clamp on the lever to crack. Under warranty though, just waiting for it to come back.. Replaced with an echo tr and can say they do slow leak, but nothing a small topup in the bleed hole cant fix every couple of rides
