Replacing brake lines

Hey all, this past Sunday my main rear brake line greeted me in the morning with a pinhole leak while at an off-road park 1:30 away from home, ultimately leaking all of the fluid in the brake fluid reservoir and leaving my rear brakes useless except with the parking brake. Fortunately the front brakes still work so I could drive home, carefully. So I tried fixing the line with compression fittings at the park but ended up putting a larger leak in the brake line because the line was rusted to the hex nut which just twisted the line. So I'm either debating on either getting a roll of brake line and forming the brake lines my self or getting pre formed solely because I don't have much money in reserve so I want to be aware of cost. Also what do I need to do beside pb blast the crap out of these nuts to unattached the lines? Will I need new parts besides the lines? Thanks

If you have one bad line, absolutely replace them all. Just grab rolls of line and the fittings and start making them. Easiest way to remove the nuts from your flex lines, proportioning valve, etc. Is just to cut the line off right at the fitting and then use a socket and ratchet or closed end wrench. preformed lines save time and headaches, but ultimately its what convenience is worth to you. Get or borrow a line bender, will save you from kinking if you've never done them before.

I'm definitely replacing them all. How much cheaper is it to do your own lines?

Replacing brake lines is best when you do them all unless the others look new. As they age when you replace one the others go soon. That being said I prefer using the titanium/copper lifetime ones. They bend easy and you can reroute as you wish. There is a kit available for all the flares you need to make. Just be careful to follow the old lines and keep in mind places where movement in suspension could be an issue.

On a stock replacement there are many pieces which make up each individual line for replacement purposes. By using one rolled piece you eliminate fittings and it ends up being cheaper. Keep in mind as noted by another poster bend slow and easy as not to kink the line.

Is not having the fittings in there ok? Like is having just one line fine? Also what is the flare kit? I don't have any of the special tools needed for this so will that increase the cost more than the $170 cost of getting the stainless pre bent pre flared lines?

The fittings in between are just for replacement purposes. You can make it one piece without any issues. The flare kit is available at any parts store and isn't that expensive. I would think buying the kit and line would be much cheaper than prebent preflared lines. One thing to keep in mind is to make sure you don't get any dirt or debris in the lines while installing. Put a piece of duct tape on each end until you are ready to connect.

One more thing to throw at you is to bleed all lines a few times once all lines are replaced. Brake fluid absorbs moisture and needs to be changed out. Lastly make sure all your bleeders on your calipers open prior to changing out your lines. Sucks to find out you cant bleed after getting into all this. Dont sweat the job its really not that difficult.
