Brake Line Size/Diameter

I'm sorry I couldn't really search for this information, but I was wondering if anybody could tell me the brake line size/diameter for a 1996 Jeep Grand Cherokee Laredo with the 4.0L. If you can I'd appreciate it. Thanks.

Brian

Uhmm... I'm buying this Jeep and the person I'm buying it from said if I find out what diameter they are he will put new ones on it. The Jeep is an hour from my house and I'm not driving up there just for that, not if I don't have too.

If the guy doing it can't figure that out himself I wouldn't trust him to check my oil, never mind new brake lines.

just go to the parts store and ask for the line. then measure it if you want or they might have the specs.

If you mean the brake plumbing (steel tubing), it's 5/16"...I just re-did mine.

However, I'd have to agree with oldfamilyguy on this, I wouldn't trust the guy to change the line. He has the vehicle and couldn't just take a quick look for himself? Unless the lines are seriously jacked up causing it to be unsafe to drive home, you should do it yourself. All you need to do is measure the length required and have the parts store cut it for you. While you're there, pick up a quart of DOT3, some new fittings and borrow a hose flare tool. If you're not sure, you can always pull the line you want to replace and do it all at the parts store. Then all you have to do is re-attach the line, then flush and bleed the system. <----not optional

Dragging this back up because I was searching and noticed this last post.

Brake lines, the hard lines, are 3/16" diameter, not 5/16".

A 5/16" diameter hard line would be equivalent to an 8mm diameter line which is hugimongous.
