An emergency message came on telling me my brakes were losing power band I needed to pull over to a safe area. I was on the freeway! I could not push down. I had to use the parking break and go into a lower gear to get to the shoulder then my car came to a stop in the crosswalk of the freeway exit. Vacuum pump stopped working. Went in to replace it and the backside is decentigrated into the motor. Needs camshaft assembly/exhaust replaced, investigate the motor to look for pieces so they don't damage the motor, no gear at the end of the vacuum pump, it has gone down not the motor.
