hey i have a 2011 gmc sierra slt with disk brakes in the front and drums in the back... whats a good brand of stainless steel brake lines to get for my brakes and if i do get them do i need them for the rear as well since they are drums

 

Are you talking about braided lines? Or why do you need new lines

 

Crown performance makes some really nice ones.

 

Classic tube sells them as we'll.

 

ya braided lines... i herd ou will get better brake response when you replace them with these

 

check out this website
Ive heard it helps too, however you ONLY replace the soft lines, so from frame to caliper and from frame to junction at diff housing. Ive been told if you were to replace the entire brake system with these braided lines you'd lose braking power because they allow expansion, just less expansion then the factory soft rubber lines.
I may be wrong, but hope this helps
