I installed a mechanical brake light switch on my TR3A and want to remove the old hydraulic switch. I want to buy a brass plug for the hole and I was wondering if someone can tell me the thread size/count that I will need for the plug. Thanks!
Regards,
Bob
 
1/8"-27 NPT. Local hardware store should have something to fit.
 
Just a thought, Bob, the pressure in the braking system can go quite high during a panic stop. An ordinary hardware store plug is usually only rated to 200 psi (if at all). Sure would hate to have it fail just when you need it most.

MMC has a 3900 psi plug for $1.36.
