I need to replace the bleeder screw in the left front brake caliper (drivers side) and I would like to run a tap into the caliper before doing so, to clean the threads up.. Does anyone know what the thread type is?
Thanks for your help

 

Not offhand, and I've seen different sized bleeders depending on when and who made the caliper.

It's the original caliper and it turns out the the thread is 7/16-20.
I just replaced the bleeder screw as i was unable to find the tap quickly. seems to be fine no problems
