Hello All, our 2013 Prius Plug-in had its ABS, Brake and Traction Control Lights on the dash. I used an OBD2 scanner and found code C1391. Some searches lead to replacing the Brake Booster which the dealership also confirmed. Some videos show that the replacement is pretty simple. The dealership is going to charge $3600+ for replacing the brake booster with master cylinder and brake booster pump, after some searching I am able to get both parts for about $1200 and the dealership can bleed and calibrate for about $800. I am planning to do the replacement myself to save some money. For anyone who many know or has done this replacement do you have any suggestions or pointers.
