RE: Genuine Brake Fluid?
Well, I think I may need to get more familiar to take off the wheel. I took off the tire only two times in my life when my tire was flat. I changed it to spare tire and went to auto shop to get the real tire. So, I didn't worry about that much regarding the torque when I put the wheel back.
How much torque do I need to apply? Or I don't have to worry about that much. I don't want my tire off while I am driving. It scares me -_-))

ORIGINAL: 2POINTautO
JUst wanted to answer a portion of your questions, an actual complete flush needs to be done, not just refreshen the reserviour. Heat attracts moisture so all the water in the brake fluid works its way to the calipers and starts to coreode them from the inside. Brake fluid itself is hydroscopic so it acts like a sponge and soaks up moisture over time through the reserviour cap, this is why you never keep open brake fluid on the shelf or keep closed brake fluid for more than 2 years, this is one reason they started selling small bottles of fluid.
Enough moisture in the caliper can start to boil and expand, this will actually apply the brakes and lock up a caliper or two while driving at highway speeds, you pull over and in a few minutes the brake unlocks and you can drive again for many miles and they can lock up again leaving you dumbfounded as to what the proplem is, its water in the caliper.

reservoir change alone is as pointless as a race with no turns [sm=burnout.gif] j/k, I like a drag as much as the next guy.

Turkey baster out the old fluid in the reservoir, refill with new fluid, bleed until clean fluid comes out. Keep filling the reservoir while doing this or you'll do more bad than good. Should be easier with the vacuum pump. or even easier to pay $65 if this is what they are going to do.

RE: Genuine Brake Fluid?
^ That's what I figured, but I wasn't sure. I guess that would be kind of a PITA. But I always say If I can do something myself for way cheaper than a shop will charge for it, I'd rather do it myself. Plus, unless you watch the shop do the work, how can you be sure they really "flush" it and dont just suck out old and add new? I just don't have a lot of trust in shops anymore I guess.

Me either ..... I have a mechanic that does work for me outside the shop that he works for. I tell him exactly what I want and pay him cash for his work. It's also much cheaper for me and he makes more money, so it's a win-win situation, except for his boss who's pissed me off on more than one occasion.

RE: Genuine Brake Fluid?
A flush replaces all the fluid in the lines & calipers. Not just the fluid in the reservoir. Kinda pointless to replace the fluid in the reservoir & leave old dirty stuff in the calipers.
I bet the shops will do a real flush. Price difference probably reflects how careful they work, whether they're set up to do this quickly, and whether they really need/want the business. A shop that bleeds brakes constantly might have everything set up like an assembly line. A shop that has a long waiting list might see this as a nuisance job & price it high.
Pressure bleeder FTW!

This works a lot better than vacuum bleeding. (I've done both.)

RE: Genuine Brake Fluid?
Haha! I don't work on my brakes enough to warrant that purchase when I can still do it the old fashioned way! It is pretty cheap though. I am afraid by the time I figured out how to work the thing I could already be done bleeding the brakes manually.

RE: Genuine Brake Fluid?
Thank you all!!!
These are very valuable information to me and I feel like I am getting a real car owner not just a driver. I will try it by myself and think it might be a fun thing to do at this weekend.
