Replacing both L & R Front Brake Calipers on 99 WJ - Can I just bleed front brakes?

That is the question. I have the 99 WJ quadradrive and I am replacing the calipers. I am wondering if I need to bleed all four wheels or if I can do just the fronts? I bled them all 6 weeks ago so the fluid is new. I understand when you bleed 4 its rear right then rear left, then front right and front left. I am assuming the fronts are on a different line from the master cylinder and thus the question, can I just bleed the fronts?

Just came out of the mountains with terrible vibration in the front while braking so I am upgrading to the akebono in the front (could not get to it before my trip).

i did just the ones i changed, even with abs. my wj pedal is softer than my xj"s but it stops good and pedal is not low.
thinking i gravity bled too. worked for me. i use a cement block as a helper when bleeding.
oh,abs works great too...

Just bleed the front, it wont matter which one you start with. Just pick one and bleed completely, then switch to the other side and do the same. Double check you pedal, if you need to go again, do another round until you get a hard pedal.

While replacing the calipers, I would suggest replacing both brake hoses if you haven’t replaced them already. I’ve experienced the hoses collapsing internally and not allowing fluid to return to the master cylinder. The end result was the caliper not releasing.

Only need to bleed the ones that were replaced, the front and rear are not connected.
