Default lazy brake fluid change?

Car ('96 Camry 4-cyl.) needs a brake fluid change. I was wondering,
would it be advisable to change the fluid by sucking it out (with the
ever-useful turkey baster) from the brake fluid reservoir, and
replacing with new fluid (is it DOT-3?), once a week or so? Would the
fluid mix properly from within the brake lines, master cylinder, etc.?

Pep Boys charges $35 or so for a brake fluid change in my area, but to
get the car there is a logistical nightmare: pack wife and kids in the
second car, I drive the car to Pep Boys, we go shopping in the other
car, then pick up the car from Pep Boys later in the day. How would I
know Pep Boys really flushed the fluid, instead of just sucking out the
dirty fluid from the reservoir? And then, aha - maybe I can do the
same thing...

Thanks,

Michael

=============
You can do that and it can be helpful, but primarily for the master
cylinder.
To get clean fluid all the way back to the rear wheels, you need
something like this:

Now that you mention it...

I took the 10-yr-old car (137k miles) for a brake fluid flush for the
first time ever last winter. The guys at Brake Masters said that the
stuff was "like syrup" coming out, and would need *another* flush in
about 3 months' time.

Sure enough, although the fluid was clear at the time, 3 months later,
it turned dark again.

So it's due for its, um, 2nd flush. Was just wondering if I could save
a bit on the logistics by doing it myself, turkey-baster style...

Btw, brake fluid is the nasty stuff that can dissolve car paint right
off, right?

Thanks,

Michael

The Power Bleeder from Motive Products works great. They posted the
instruction on their web site. You may want to check it out. It's not
much more than a set of Speed Bleeders. I use the universal reservoir
adapter version.

Don't know how I got along without it. Others use the MityVac pump. But
turkey baster won't do, because brake fluid doesn't recirculate to the
caliper/wheel cylinder.

Do this once a year on all cars with 1 qt of brake fluid. Castrol GT
LMA (Low Moisture Activity), Valvoline Syntech Dot-3/4, or Pyroil Dot
3.

Yeah, in general we shade tree mechanics start with the simple stuff,
and gradualy take on the more difficult ones. One step at a time.

An 8 mm box wrench (at least on my car), 2 feet of 3/16" ID rubber hose, a
$4 one way check valve from Pep Boys and an empty windex bottle with spray
pumper plus an hour of your time (first time) is all you need. Pump the
resevoir dry with the pump from the Windex bottle and pumping old stuff into
the bottle itself. Fill resevior with new fluik. Take off you left rear
wheel, open the bleed valve, attach hose with check valve, stick valve in
bottle fluid. Go pump pedal nice and slow and no farther down than
pedal/piston normally travels. Watch level in resevoir, it will fall fast.
You must refill and not let it get too low or you will introduce air into
system and have to start over. Check the resevoir about every 10 pumps just
to be safe. Check condition of fluid coming out at wheel. When it flows
clear, you are done with that wheel. Tighten bleed valve. Now do the left
rear. Then right front. Then left front. If your jack will go high
enough, you can rotate the tires from front to back during one of the bleeds
for each side. I usually do it when I bleed the front. It means taking the
back wheels off twice but that only takes a few minutes.

I am sure there are more precise directions somewhere on the net. Somebody
please correct anything I forgot or is not clear. I got mine from the
Haynes manual.

You save money, don't have to load up the kids and you will know the job was
actually done and done right. Get your wife to come out and pump the pedal
and then job will be even easier.

why can't you just let fluid flow out each wheel until all are empty, then
add new fluid, then bleed brakes until air is expelled?

i'm not too much of a mechanic. just asking.

Air can get trapped in the system, particularly the master cylinder,
which is very difficult to get out by the pedal pump method. That's why
people bench bleed the new master cylinder before installing. I use a
Motive Products Power Bleeder, which is a modified garden pump with a
pressure gauge and a universal fluid reservoir adapter cap. Works well.


You can read www.motiveproducts.com instruction page on how things like
this work.
