yourself a favor and buy a brake bleeder wrench.
you can bleed your brakes with just a vinyl hose and jar, I found
that using a kit like this make the job easier to do and it's cheap.

your master cylinder in between wheels to make sure that there is
enough brake fluid in it. Do not let this run dry.
Your Jeep Brakelines
you just installed a set of new brake lines or worked on your brakes
in a way that required you to disconnect any brake line, it is absolutely
necessary that you bleed your brakes before you drive anywhere. Failure
to do so will result in poor to nonexistent braking due to air bubbles
trapped inside your brake lines. Symptoms of air bubbles trapped in
your braking system include an excessively soft brake pedal or a pedal
that goes clear to the floor without any resistance. If you have any
of these symptoms even though you have not worked on your brakes,
check for leaks, fix where necessary and then proceed to bleed your

your Jeep on a level surface, apply your emergency brake and put your
transmission into gear.
3. If you worked on your master cylinder or disconnected
multiple brake lines for whatever reason, you will need to start this
job from the passenger side rear brake. If you just worked on your
front brake lines, then you need to start at your passenger side front
brake. The idea is that you just need to start from the brake that
is farthest from the master cylinder.
4. Assemble your brake
bleeder kit so that it looks like the image to the right.
5. Climb under your
Jeep and remove the rubber cap attached to your brake bleeder valve/nipple.
6. Place your bleeder
wrench on the valve/nipple and then insert the tapered fitting into
it as shown to the right. Attach the jar using the magnetic head anywhere
below the nipple.
7. This is where you
could use the assistance of a helper. Have them sit in your driver
seat with the engine off. On your command, have them push down on
the brake pedal slowly but as forcefully as they can.
8. While they are pushing,
slowly open the brake bleeder valve/nipple until your helper notifies
you that the pedal is on the floor. At this point, close the valve
and tell them to release the pedal. Repeat this process as many times
as is needed until no more bubble come out. Depending on how much
air you have in your lines, nothing may come out the first couple
times you do this.
9. When only fluid comes
out of your brake system, tighten your bleeder valve closing it off
and replace the rubber cap.
10. Check the fluid
level in your master cylinder before you continue and refill as necessary.
It is very important to NOT let your master cylinder run dry as it
will suck in more air and make your problem worse.
11. Proceed to the driver
side rear brake and repeat the process.
12. Again repeat the
process on the passenger side front and then the driver side front
That should be it. Please let me know if you have any questions.
