Changing brake line....3 quick questions.

[joedav1228]

I am going to change the hard brake line that spans between the rear left and rear right wheels of the car. It appears to go from a peice on the frame up and over the gas tank to the same spot on the other side of the car.

An Autozone person sold me a bunch fo 3 1/16 line and I bought everything else I need but I have some questions.

1.) Is 3 1/16 the correct size?
2.) What size wrench do I need to un-screw the hose fitting that is already on the car.
3.) What size is the bleeder screw?

I am only asking because I would like to have the tools ready for tomorrow (I'm in work now). I'm work in 95 degree heat, 90 percent humidity and laying on black tar in an area with no wind/shade and a ton of bugs.

If you can's can answer those questions it would help so much.

Make sure the lines are metric bubble flare.GM since the late 80s has used bubble on all its cars.If you were sold inverted flare,thats wrong.

I would go buy a Haynes manual, I bet they would tell you the sizes you need.
