I installed new front brake lines in my 2013 jku rubicon. Do I need to Bleed all 4 brakes or just front? Is there an order to follow? Do I have to do anything with the abs? I made sure my resivor stated full while replacing the brake lines and the brake lines were off for a few days if that matters. Thanks in advance.

 

How old is your Jeep? If it's more than a couple years old, bleed them all to get new fluid in the system.

Start with the wheel farthest from the master cylinder, and work closer.

 

It's only a few months old. Do I need to do all 4 to get the air out? Thanks.

 

Maybe not. I have replaced one line and caliper in the past and needed to bleed only that brake.

Try it. If the pedal doesn't firm up, you will have to do them all.

 

I installed extended ss brake lines on mine & had to really tighten down the crush washer bolts to keep them from leaking. The after market crush washers were harder material than the factory ones. FYI

 

Gravity bleed it. Just open the bleeder, and uncap the res, when it starts flowing, bleed it normal and test the pedal. If there is sill some play bleed it from the furthest tire (rear passenger) and work your way to the front drivers side.
