A few questions on this topic?

1. what makes it turn from transparent to black?

2. How long does it have to black before damage is done to the hydraulic chamber?

3. when you change it and bleed the system, does it clear the lines and make everything new again?

4. Does it turn black faster in cars with 4 wheel disk than cars with disc and drum?

 

You bleed the lines to get airbubbles out of the system.

 

1. Minly heat but also time, inpurities in the system/lines etc. will have an effect on it.
2. Depends on the grade of brake fluid you are using. Some last longer than others. It is recommended to replace the fluid at least every 24 months.
3. If you bleed the system so that clear fuild comes out from every bleed valve, you should have everything out.
4. I doubt it...

how do impurities get into a selaed hydraulic system...it's an airtight system isn't it? do cars with 4 wheel disk take more fluid than front disc?

 

The brake system is supposed to be sealed, but it is not. Every time you open the fluid reservoir you may have impurities go in there. Also, the heat buildup forms all kinds of impurities, too.

I don't think there is much difference in the amount of brake fluid between disk/disk and disk/drum.

What is meant by "hydraulic system" what does hydraulic mean......isn't the ac system also sealed and hydraulic?

 

Damn!!! You're really testing me here...

A "hydraulic system" means that the system is operated by applying pressure to the fluid which then moves the moving parts.

That is probably not the best and most accurate description, but it should give you an idea what that is all about.

A/C is a sealed system, but to my knowledge it is not hydraulic.

BTW, check out www.howstuffworks.com too. Lots of good and maybe even more accurate info there!

hey don't think i don't appreciate the knowledge professor.........

 

I'm honored...
