Be gentle with the bleeder screws. The originals as well as the Speedbleeders are soft and don't take much to seat them. I overdid my originals and they came out slightly crushed. The reddish brown thread sealant on the Speedbleeders tends to come off easily so I added teflon tape and that solved the problem. My Speedbleeder Installation Notes says:
"When the Speed Bleeder bottoms out, tighten to 32-40 in-lbs torque (not ft-lbs!!!!)" "Don't over tighten"
