    Squishy brakes

    So the brakes on the vert are weird. Sometimes they have a nice positive feel, others it goes all the way to the floor. It slows down, just not well. If its going all the way to the floor, I can pull my foot off and press again and it'll be fine. Fluid seems very clean, new almost. No leaks on driveway. Is it possible they changed fluid and there is an air bubble in there? Anything I should check?

      Air in the system would always result in a soft pedal. But a failing master cylinder can (initially) result in occasional problems. Replace the master cylinder, flush the system, and see how it then behaves.

            Flush the brake system and then see if the situation has improved. Also check to see if the pads are worn to less than 1/4" and replace them and the rotors if that is the case.

              Master.
              This happened to me, tried bleeding it. Then found out the rears weren't working at all.

              Try bleeding first. If you can't pull any fluid out of the rears, or it doesn't improve. Replace the master cylinder..
