[quasi]

Thanks to Lee, Ruedi and Erik for your help. My brake light switch was in fact a 2 pole switch with an 1/8" NPT connection. However I was too slow and clumsy in replacing the old switch with the new, and enough brake fluid escaped to cause the brake peddle to bottom once the new switch was installed. My guess is I will need to bench bleed the master cylinder as well as bleed brakes. I have not done this yet on a two liter. Just wanted to check with you all.

Does this approach make sense ?

Any experience with bench bleeding a master cylinder or bleeding brakes ?

Thanks again for all your help.
