Hi everyone. I drive a 2002 Sequoia and I am hoping someone has some insight or advice for me. The other day my calipers sounded as if they were "dragging" or not fully receding to the normal position after braking. I jacked it up and inspected everything, but when I reinstalled my wheels I have no pressure at all and my foot went to the floor board. I assumed it was my master cylinder so I just completed replacing it and bleeding my system however I have the same problem i.e. no pressure in the system. Just curious if anyone has had a similar issue? Could it be my brake booster or ABS, VSC sensor? Thanks for your help.
