Autozone Brake Fluid
What is the spec for brake fluid in our trucks? I'm stopping at Autozone on my way home so I can flush out my lines. I replaced the hard line on the frame because it was rusting near the fuel tank.

Use DOT4 fluid.
It's compatible with DOT3 systems but has a higher temperature range. If all they have is DOT3 that will work.
DO NOT USE DOT5. That's really the only way you could screw up this job.
Also, bleed your front brakes. I replaced that same line several weeks ago and only bled the rear calipers.... and the pedal feels funny. I think some air got in the front lines. Though my line was busted through and ran the reservoir dry. Either way, it's a good time to flush out the front.

Just bleed 'em until the fresh fluid is in the system, leading to each wheel, displacing the old fluid.
Completely changing the fluid during a bleed is one reason some guys will alternate brake fluid colors each time they do a flush, using ATE Super Blue one time, then the next going back to the standard golden honey yellow colored fluid. That way they know when the each line leading to each wheel has fresh fluid.
Lightning guys that autocross and road race a lot do this regularly, swapping back and forth between the Blue and the standard.

The same way you bleed 'em.

Make sure you refill before it gets so low as to let air into the lines.
Me personally, when I flush my fluid, I use a baster and remove as much as possible, then I "push" the old fluid through until nothing but air is going through, but that's because I use a Motive brake bleeder so its EXTREMELY easy to flush the lines on all of my rigs.
