Hi guys. I was wondering...my jeep is a 95, so the brake fluid in there is 8 years old. Do I need to change it?
If I do change it, how far do I push in the brake pedal? I read in Popular Mechanics once that on an older master cyl, light crud and corrosion builds up on the inside of the cylinder beyond the furthest extant of the pistons stroke. This means that when you are bleeding and push the brake to the floor, the seals in the cylinder walk over this crud and get roughed up. This can ruin the master cyl.
So...is this true? It would take forever to bleed the brakes pumping it an inch at a time, and it would be hard to make a stop that is exactly the right length. A bit too long, and you might as well not have a stop at all. A bit too short, and you are pumping all day.
