Does anybody know what size the brake line fitting is for the lines that come out of the proportioning valve to the front right brake caliper?

I'm running the lines down along the k member on my 88 project car and I seem to have misplaced my original line for the use of the fittings. I would like to get some new ones but I don't know the fitting size/thread count. If anyone also has an old line laying around, I would be willing to purchase them from you. PM if anyone has some or post here if anyone knows where I can get some new ones.

Thanks,
Jesse

It's either 3/8-24 Inverter Flare or the size about that....7/16-24 i think.

Not sure really. Autozone sells sticks of 3 foot brake tubing with two fittings on the end. They are 3/8-24 but the whole stick is $2. You can buy one and check that way.

But part of me wants to say it's 7/16-24

I think its 7/16-24 the rest of the lines for the car I think is 3/8ths-24. Just wanted to hear someone elses opinion, and you are the brake king lol. You have quite a wealth of information about brakes for these cars. lol

the drivers side line at the MC is 7/16 so the other end would probably be 3/8 since its smaller, or at least thats how my car is

I don't know everything, i just research the hell out of everything and find all sorts of useless info.


Oh BTW, if anyone else decided to use an SN95 prop valve, the rear fitting on the valve is an M12-1.0 threaded Bubble flare.
