I'm going to flush my brake fluid in the next few days. Before doing that I need your opinions of how many bleeding valves on the same caliper should I open during the flushing process.

My car has sport brake calipers that have two bleeding valves on each caliper. I know the proper process is to bleed the outward valve first then the inward after.

My question is does it make any difference if I just bleed the fluid through the outward valve and skip the inward one? The reason is that with this way I don't have to remove my wheels since my rims have plenty space that I can just connect the tubing to the outward valves and start bleeding the fluid.

If it make significant difference then I guess I have to remove the wheels and do it right

Thanks for your opinions in advance,

 

Bleed them both if you want to do it right and get all the old fluid and air out if the lines. Just bleed what's convenient and easy if you just want to get most of it and don't care about thoroughness.
