it is recommended every two years though most folk never bother. as brakes are doing OK see when your next major car service is due then have it changed then if worried.
Brake fluid isn't replaced (usually) and doesn't need to be replaced on a regular basis. See your owner's manual.
1) Polyester is synthetic (person-made); cotton is natural 2) Polyester doesn't wrinkle in the drier like cotton 3) Polyester sticks to you in hot weather but cotton cloth doesn't 4) Polyester tends to be thin, but cotton can be thin like East Indian clothes or thick like corduroy 5) Polyester needs a lower setting of iron than cotton 6) Polyester dries faster in the drier than cotton does 7) Polyester clothes are cheaper than cotton clothes 8) Polyester can be made into fancy cloths that shine in the dark things, but cotton can't have that much done to it, especially. 9) Polyester is recognized as less fashionable sophisticated by dignified buyers
Polyester does not shrink, does not loose color, that I have seen. It is very cool in the summer and does not soak up sweat, like cotton does. It is fast drying. Cotton, once wet, stays wet for a long time. This could be dangerous if you are in a survival situation. Cotton kills, as they say. The only issue that I had for a minute with polyester, was that for some reason they hold body odor and you have to wash them in hot water, not normal wash. I imagine they might be a bit cool in the winter months, but if you get wet, remember that cotton stays wet and becomes heavy and polyester is fast drying. There is a good reason why you see athletes using polyester instead of cotton. It is thin, light and stays light, while cooling you off. god bless!
