Combination valve

Hey guys,

I pretty much have the brakes plumbed except for the point where the rear line attaches to the combination valve directly under the master cylinder. I was surprised to find that the the stock brake line fitting coming from the rear to the combo valve was a size too small. Is this a common problem and what size do you think I need to adapt my stock line to the valve?

Thanks,

Hey man, you can get an adaptor to adapt your current line to the prop valve.I've done it alot, you can get them from the twilight zone(auto zone) or other parts houses. Make sure you get one with the proper threads and not one that's close enough. Sometimes they feel like the correc threads and dont have a "seat" in the bottom of them to seal against the fitting. If I had the part number handy I'd give it to ya for the most common one I use.

Thanks AX, I guess they were successful because if they were the same I may have just been that dumba** you were referring to. J/K
