How to change the brake lines/hoses?
What does it take to change the brake lines?
1) bleed the system dry
2) change the lines
3) fill the system with the new fluid
???
How do you make sure you don't have air in the system?
Thanks.

Which lines are you changing?
We'll say you are taking off the drivers front.
Pick up a few brake line caps. When you disconnect the lines, you'll want to cap the lines that are staying on the truck so that you don't lose excessive fluid.
At the bottom, you'll cap the end of the caliper the same way.
KEEP AN EYE ON YOUR BRAKE MASTER CYLINDER THE ENTIRE TIME YOU ARE WORKING ON THE BRAKE SYSTEM. YOU DO NOT WANT THIS TO GO DRY!!!!
Take the caps off one at a time when you replace the line.
CHECK THE MASTER CYLINDER AGAIN
top of the master if it starts to get low.
Bleeding the brake system will either take a mityvac or 2-people "generally"
On person to open the line to bleed and the other to push the brake pedal to push the fluid/air.
You'll start with the rear brake proportioning valve, RR, LR, RF, LF

BTW I will be changing 4 rubber hoses - 2 front, 2 rear.
Rear - to accommodate to suspension lift, front - because I'm doing rear anyway.

Be very patient...Soak the lines very good with rust penetrant and try again. Yes the Rears are a pain. You might even need Heat to get them loose.. thats how to change a brake hose..

A 10mm brake line wrench is very useful. 2 hoses up front, one hose in back on my 3rd gen 4runner, remove the rear spare to get better access. it's there at the diff. Same as the fronts except there's more steel line to get the air through when you're bleeding them.....make sure not to run your master cylinder dry.

it took me half a day, including the fronts and a trip to the store for more brake fluid.
Dont forget these; just in case something bad happens.
