you don't have to bleed them unless you have a leak or get air in the system

You bleed your brakes is when you replace a caliper, change a line, if there's a leak, etc.

I've also found that fluid that is extremely old once changed does make a difference. So if you think that the fluid in there is what came off the assembly line I would consider flushing the system, but at the moment is not neccessary to do.

ok heres the main question how do I COMPLETELY change the brake fluid over without getting air into the system and not mixing the two fluids? I SHOULDN'T drain the brake system dry right?

To flush the system I just bleed out twice the capacity that the lines & resevoir hold (not sure what it exaclty is right now),
making sure to always top off the resevoir up front.
I do this from the rear driver side.
Then I bleed the other 3 corners as well in this order:
1. Rear Passenger
2. Front Driver
3. Front Passenger (with ABS).
Never let the resevoir go empty when topping it off.
I don't think it matters if it mixes in the process, because the ratio of old to new fluid when done is very small.

Oh yeah,
& don't re-use brake fluid that has been sitting on the shelf half-full for a long time.
There's a chance that the cap might not have been on tight & moisture got in.
I know some of you have a half full bottle sitting on the shelf of your garage right now.
So go on, get out there & throw it away :)
It's not expensive, just get a new bottle.

Also, careful taking off the bleeding-nut on the calipers.
Soak 'em good first.
They can break easy, especially if they are old.
I've done this once before.
Cursin' & throwing sh*t.

No not 'need' to. Good to flush out the old though
occasionally.

> u change ur pads and im like WTF?

Not a Bad idea. :-) Rather cheap insurance.

All Very good advice. :-)

The same thing happens In the car, Brake fluid can absorb some
moisture. It could lead to rusting the lines from the inside
over time.

Worth it to change the fluid when it starts to turn brown.
Which Might be after a year or two depending on how hard the
brakes are used ?

With Subarus we would do a gravity bleed every 30k. You would only add 1 qt of new fluid so it wasnt really a flush.

Okay why does everyone think that you bleed the rear passenger? because I KNOW FOR A FACT that you don't on the 165. You have to bleed the passenger front first. If you'd like an explanation on why. Look at the braking system diagrams with abs. You'll understand then. I believe it is the same on teh 185 but not completely positive.

Hope this helps.

Isn't the 165's ABS actuator in the rear?
