I have a 2016 scion tc, 73k miles, automatic, recently changed the rear rotors and break pads by myself and bled the breaks, after I finished, I noticed the break Pedal is soft and have to put more force to make the car stop, and when I turn on the engine while engaging the break Pedal, it feels like misfiring but it turns on just fine, I tried bleeding the air out of the breaks, it didn't work, for both the rear breaks, I heard a tsssss noise while bleeding, but the front breaks did not have that noise, do I have to rebleed the breaks, and if so, how should I do it by myself
I'm assuming that system has anti-lock brakes. If so, you're going to have to pay a guy like me to bleed it cuz we need a special computer that activates solenoids and tells us what to do. You can't bleed an ABS system that has air in it without such a machine
