I am getting ready to replace my brake master cylinder, and am wondering if it is worth it to replace all the break lines at the same time. It can be down for however long, I have a DD. Is it worth it for a 89? 22 Years old? Or do they hold up just fine? Anyone had any brake line problems not counting problems from lifts?

 

not a big deal to replace all the brake lines, unless yours are weak or corroded.
what booster are you installing? you doing the dual diaphragm booster upgrade?
do you have abs?

when i did my booster upgrade, i replaced just the lines going from the booster to the proportioning valve body.

 

I dony have abs, I was planning on just replacing it with something OEM but if there is a upgrade may as well do is now, what is the other booster you are speaking of?
