So, one of my brake lines gave out yesterday. It was leaking out near where the fuel fill goes into the tank under the truck. Is this referred to as the rear break line? Are the rest of the brake lines most likely to follow and brake also? Just wondering if I should replace them all? I really don't want to end up in someones living room because my brakes **** the bed.

As always, I appreciate your help.

 

Look at the lines going to the tee on the rear, if they are rusted bad, might as well replace them all, the one you are talking about the parts store might not have you might have to make your own, I think it is a 3\16 line, the parts store has them in lengths.

 

I always make mine, it's much cheaper that way. On my Pontiac they went out one after the other, but it is 38 years old.

 

I've been poking around online looking at some prices. You weren't joking about the price difference!

It's a pretty straight forward job? Just kind of bend them and fasten them to the frame as you go along?

 

Remove the old one and run a string down the length of it, along the whole length following the bends. Then measure the string to see how long a line you need. You might have to get couplings to put pieces together. Get a tube bender and bend it up using the old one as a template. Some bends are easier by hand but don't kink the line. I don't like making the double flare ends so I try to get the proper length using what's available or bend the line in such a way as to take up the extra line or run it a way to use a shorter line. If you change the whole thing front to rear then start at the rear and coil up the excess under the master cylinder like the factory does.

 

Finally got the brake line done. Seems to be working fine. I only did a 5' section going to the rear from the coupling; it was already flared and I just had to bend it a bit by hand at the rear end. It was my first time working on a brake line; it went pretty smoothly. I still think I need a master cylinder though. The brakes seem a little squishy.
