I'll help you, if you explain this question to me. I think I might have missed another thread you started, that's why it's important to keep all your questions in one thread....

Phone acted up just needed to find the bore or. The opposite of the nut is the female?

 

[firemanjim]

When a bore is referenced with a master cylinder, they're talking about the bore the piston rides in. What nut are you talking about?

I feel stupid so which is better

I'm not sure I understand what you want to know. If its what size master cylinder bore, you only need a 5/8 bore. It's a go kart..... Cars use a 5/8 bore and 3/4...... Post a link to the brakes you're looking at buying..... It will help.....

The $40 master cylinder, right? What nut are you talking about? What bore? The ad says it is a 7/8 bore..... So what exactly are you asking? The 7/16 nut that goes where?
Also, please don't start multiple threads asking the same question. It's frowned upon here.....
The majority of us are here to help others. But in order to give the help, we need a clear understanding of what you're asking. Your thread title says bore size, but then you start talking about a 7/16 nut...... I'm lost.....

I thought they have different nut sizes

Like What jims said, what nut where?

 

[jmv350]

OK well on mine I have two of them for the break lines

 

[firemanjim]

If I'm not mistaken, those are not just standard nuts. They are compression fittings, with npt threads..... Not like a nut and bolt thread.

Those 2 brake line fittings that come on MPC master cylinders are made for use with 3/16"-size brake line, that you could order from this page: https://www.bmikarts.com/mobile/Hydraulic-Brake-Line--Plastic-_p_549.html
