Hi Guys and Gal,I want to plug the front brake pressure port on the master cylinder,what is the thread size, I'm assuming NPT ?,perhaps BSP, please point me in the right direction. Thanks. ride safely. James
Thanks, Mr B., I thought it was but couldn't check quickly. I have a suspicion that Lockheed always used UNF up until the late '70s. Thank goodness they didn't choose that nasty tapered National Pipe.
I've complicated life for myself by fitting one of those Variable Ratio Master Cylinders and they had gone continental by then. The hydraulic unions are ok using stainless - still 1/2" AF but I have to carry a metric (ugh, wash my mouth out with soap and water) spanner for the lever and clamps.
