Yo Scotty I got two questions. First, my car's owners manual recommends changing the steering rack rubber boots every five years. But, the car's 24 years old, they've never been changed and the rack's just fine. And second, i want to get my brake fluid changed but my mechanic told me "Do it yourself, but just change the fluid in the plastic reservoire and don't bleed the air out of the system", cuz he's afraid the master cylinder will fail. What do you think, sir? Thanks in advance.

It's something I've been told back in my youth by older mechanics as well, to not bleed the brakes using the brake pedal if they haven't been touched in a long, long time. One argument was that the master cylinder bore is "worn in" with normal brake pedal usage, and if you open a bleed screw and then push the brake pedal all the way to the floor, the seals on the master cylinder will get damaged during this process as they move out of the worn in part of the bore. So I suppose if you're worried about it, you could try to not press the brake pedal to the floor, but perhaps only within the range of it's normal movement.

dumb, change em if they are cracked. Do the bleeding as he says, but then bleed each wheel too to get the end crud out
