I’m writing because I need your advice on a car. I recently took possession of my mother’s 2006 Scion Xa with 350 (yes, 350) original miles on it. 🤣 I told her she didn’t need a car way back then, but you know how mothers are. 😆 I changed the oil and antifreeze during the time she owned it just because it sat more than it was driven. But before I started driving it, I changed all the fluids including fresh gas, changed every belt and hose, new struts and shocks( I found a bad strut), all new spark plugs, new battery, and because the brakes squealed, I changed rotors, and brake pads( the best pads per your video). The engine and transmission seem fine as it should given the mileage. The only thing I noticed is it idles rough with the air conditioning on before it warms up. But then that disappears. Very zippy car for 103HP automatic. Fun to drive, too. But intermittently when I push on the brakes, it makes this “boing” sound like a spring being released after tension has been applied. So I changed both the calipers, master cylinder, too. Bled the brakes to ensure no air in the line and rechecked the brake fluid level. Still I hear and feel this annoying sound. It feels and sounds like it’s coming from the front brakes. Now, I thought perhaps it might be the ABS system, but no “check” ABS lights have gone off. And according to the symptoms for faulty ABS, I don’t appear to meet the criteria. So....

My questions:

  1. Because the car was only driven infrequently until now, what other things should I check and replace to ensure it lasts like a Corolla? Fuel filter? A full diagnostic scan? Please list.

  2. What do you believe is making that “spring” sounding noise when I push on the brakes.

I’m a museum piece as well. 😆. Thanks. I will scan her next.

350-mi.? You've got a museum piece. Leave the fuel filter alone. Start by thoroughly OBDII scanning it. Go from there.
