I think a lot of people would just never try to do it or think about any job on the car is doable by non mechanic. At least that’s how i always felt. I think it dimmed when i watched someone changing the air filter in a car. Oh, so it’s literally just open the flap and insert the new one huh? I don’t really fuck around with breaks because they make the car stop. But it really isn’t that hard as long as you know how to bleed the breaks.
