so i had my 2001 Toyota Prius for 2 years and now when i was driving it the triangle came on and started overheating and wouldn't accelerate passed 50 so we had the water pump replaced. replaced the oil, had the brakes replace, and the issue still goes on it doesn't overheat but the triangle is on we read that and it says the master cylinders out. but how does that affect the car from accelerating to 50? and when i go to brake theres this loud noise sounds like a NASCAR. any ideas?
