what is this for?? pic.
okay so i have been in need of new front brakes and i was under the truck today feeling around the rotors to see if i needed new ones or not, and i saw this line that is pretty rotted and split from where its supposed to be connected, what is it for, and do I need to replace this as soon as possible or is it something i can wait to do when i do brakes and ball joints? heres a couple pictures:
im looking at the line to the left.

That is NOT the ABS sensor. The ABS sensor attaches to the outside of the brake shield (i.e. under the brake disk). That is, if you have ABS at all.
That is the vacuum hose to engage the hubs. If you have manual hubs, this is not needed and can be capped. Do NOT leave the hose open to atmosphere, dirt and moisture can invade the vacuum area and destroy any seals (1 $40 one that I know of, possibly others) and cause rust. Left for too long, contaminates can migrate to the vacuum pump and ruin it.
As long as that hose is torn like that, your vacuum hubs (if you still have them) will not work correctly.

The problem you are facing probably comes from sticking (or jammed) slide pins. There are instructions on FTE that will guide you through fixing / replacing them.

No. ABS will not cause random hub lock ups. Failure of ABS will cause ABS to disengage and return your braking to a non-ABS type of system function.

Hose is auto locking hubs vacuum line.
while at the parts store pick up brake slide pin grease or anti squeeling stuff.
Clean everything with air blast the brake parts cleaner. Regrease and put back together.

Are they stock or aftermarket? If stock they should have auto and lock. If your vacuum is working properly u can just leave it in the auto position.
