Brake hoses and bleeding

[Welderman85]

Do I need to bleed the whole system after replacing the front brake hoses or can I just hit the fronts

Do you “need to”? No. But, if it were me, I would bleed the entire system if you’re going to be bleeding any of the wheels. It’s rather inexpensive to completely bleed the system and get fresh brake fluid in it.

Just the fronts but never hurts to do it all. Unless you're in a rust area and the bleeders are seizes.

I replaced both front hoses on my 06 Suburban recently. Since the fluid looked pretty dark and I had no history on how old/mileage, I replaced the old fluid and bled all 4 wheels.

I guess what I'm saying is take the opportunity to put brand new brake fluid while you do the job.
