if you're gonna leave the speed bleeder permanently in the caliper, SB8_125 (left pic) is a safer option. SB8_125L (long) has a longer nipple if you're *not* gonna leave
it in the caliper (you plan to put the oem bleeder nipple back on). The LL (extra long) is for the clutch bleeder pipe. I bought mines from the inventor's website
here under
the *steel bleeders* tab, then page 2.

These bags are convenient. You can empty out the bags but I still bought a few. If you have your own tubing they're half the price,
here.
