I have a 2009 Prius with 335k miles. I know, right. I got it as a gift so I really want to fix it and use it as a commuter car. My brak actuator failed, the red Brake light, the ABS and Check engine light is on. I tried clearing the codes with Techstream (v13) and the car starts with no codes, after driving for a half a mile the lights go back on with a beeping sound and only the rear brakes work.and can drive on and off like that all day. When the brake light is not on the check engine light is off as well. The car seems to have no other issues than this. I have replaced both rear drum brakes with new ones so they brake well, but the computer still reads the code: “no pressure/abnormal fluid leak”. I tried to do a full brake flush with Techstream but after I remove the relays I get “air bleed failed”. I took it to the dealer today and decided to pay 150$ for a brake flush. They have said to save my money because the car needs a new actuator pump and brake flush wont fix it. I actually have the replacement pump and want to do it following the replacement thread here, but I cannot air bleed the brakes via Techstream. Any ideas why the Techstream doesn’t work? Or should I try bleeding the brakes manually in order to do this work?
