I was trying to put off on replacing my rear brake lines till next year but that is not going to be a happening thing due to the amount of rust and leaks the have developed. So with that being said I have decided to go from the front to the back on completely replacing the entire line and I am needing to know when I remove to brake line from the ABS unit that is attached to the master cylinder will it mess with the ABS unit or not because the plan it to remove both lines one at a time to bend the new brake line to match the factory lines so I have no fitment issues. Any and all advice will be very helpful due to this is the first car I have ever had to replace the rear brake lines on. Thanks.

I don't know of any procedure or tool that will prevent getting air bubbles getting into the ABS unit. If bubbles do get it in, its really no big deal, but it may require bleeding more than usual. Just bleed the system like you normally would and either A. Goto the dealership and ask for the ABS bleed procedure from the Tech2, or, B. find a big gravel parking lot and do some ABS stops.(get up to a good speed and stomp on the brakes to activate the ABS, this works pretty good too.)

ive done a couple cars that way, the first time, i took a few lines to the carquest here. they had coils of tube, the metric bubble flair tool, and the metric fittings. for like a hundred bucks. then you dont have to mess with adapters. you have to have a tubing cutter too and make a couple test flares on the bench if you havent done it before its easier to learn that way

I have all of the tool required like the line cutter, tubing bender and the flaring tool. This is the second set of brake lines I have had to do on the car so I bought them when I did the first set of brake lines. Also could I use like a rubber plug or something along those same lines to plug the hole on the ABS unit so it don't leak out all of the brake fluid or not. Also what is the best way to straighten out a coil of 25 feet of brake line.

i dont think the plug would make much difference. you are going to get some air in it regardless. as far as straitening the tube im not sure if its the best but i just do it by hand, seems like if i try to use anything other than my hands it kinks or dimples

I am not real good at bending the steel brake pipe, nor do I like flaring the ends.

What I have gone to is copper/nickle brake lines sold at Advanced Auto. The copper nickle lines are super easy to bend. The copper/nickle also does not corrode like the steel lines. Most of the European auto manufactures use cooper/nickle.

You might consider copper/nickle premade brake lines over the steel pipe.

This link has the reviews on the NICOPP brake lines. Worth the time reading the reviews.

I was looking at the copper/nickel brake line but it is out my price range. I am also need it replace the rear brake hoses along with two fittings at the same time and do all of this on a 60$ budget.
