Default How much brake fluid would ge good?

'sup all,

I've got a 1993 Honda Accord and I'm going to change my master
cylinder, as well as replace the brake fluid that's in there. I was
thinking about letting gravity drain the fluid from the reservoir and
replace the fluid as it drains. Is that a good idea? I wonder if I
don't get it all out, how would the two different (assuming just
different in age) behave together? Old vs. New. I guess I should get
a little bit more fluid to drain it good.

Then I was going to replace the Master Cylinder. I need to take the
brake hoses off, but do I drain the reservoir first? Maybe until
almost empty. my main quandry is How does air not get into the brake
lines when I unscrew them from the old master cylinder?

How much brake fluid does anyone recommend I should get to drain
the system fully and put the new MC on? I was thinking one of those
big bottles, like 1Ltr. or something would do, though I don't know how
much fluid the system even contains.

Could anyone help me with this? How much brake fluid is in the
system? I don't want to run out, but I don't know what I'd do with
alot of extra fluid either. maybe I'll just flush until I have enough
to fill the MC plus a little bit more for later <grin>

Old fluid conains water, its going to boil at a lower temp.

Doesn't matter, you bleed the brakes afterwards. only way, since
there's gong to be air in the cylinder to push out as well

Always buy more - brake fluid isn't exactly 'honda coolant' price. Or,
alternatively, buy lots of smaller bottles, since you can't really
store open bottles (moisture gets in and it goes bad)

yep, pretty much, I think a 1l bottle should be plenty.

I googled on this a few weeks ago, just before flushing my
91 Civic's brake system.

Seems one to two 32-oz. bottles is the consensus to flush
the system. I used a little less than 32-oz after noting the
fluid coming out was pretty clean.

I use a Mity-Vac vacuum pump to bleed the brakes. It takes a
suction at the bleeder screws. A good one costs around $40.
Available via Harbor Freight, among other places.

I'd be in the free online manual at www.autozone.com for
your car for the master cylinder removal etc. directions.
Or, better, use the factory service manual for your 93
Accord at http://www.honda.co.uk/car/owner/workshop.html

buy 32oz and use it all. disgard any surplus. best way to bleed the
front calipers is to open the bleed nipple, then push the piston all the
way back in. all the old fluid gets forced out. it's disgusting too.
/then/ when you change the m/c, all the clean stuff coming through has a
really good start. the rears are less important.

wash any brake fluid spillage off bodywork immediately with water. DO
NOT WIPE UNDER ANY CIRCUMSTANCES!!! trust me on that one.

In addition to the other warnings (especially about cleaning it off paint
without delay) I would add that brake fluid is an organic oil - if you leave
rags contaminated with brake fluid in a pile they may spontaneously burst
into flame.

Disposal is best done by dumping the old fluid back into the bottle - as
mentioned, it doesn't store well once opened - closing it tightly and
putting it into the trash. In theory it can be poured onto the ground
because it is biodegradable, but that doesn't seem kosher when a better
method is available. Or, I suppose you could burn it in an oil lamp....

I couldn't disagree more. It's pretty easy, and a lot more friendly on the
environment, to store the old brake fluid and dispose of it at a repair
shop usually for a small fee or dispose of it for free at a community
household hazardous waste collection day (my community has those about 2 or
3 times a year and they're great for getting rid of small quantities of old
chemicals, oil, etc).

You can use a large syringe to remove all of the brake fluid from the master
cylinder reservoir and then bleed the brakes as per the service manual's
instructions.

I'll go along with that - leaving the details to professionals at no cost to
us. They may even have a recycling program. Thanks, Eric.

How much brake fluid would be good...hmmm...interesting question. As a
start, enough to fill all the lines and the reservoir.

Flush ALL of the old fluid out and use only new fluid. And be sure to
bleed the brakes following the manufacturers recommended procedure for
that car.

I'm more than a bit concerned by your questions because they tell me
you don't have a lot of experience working on brakes. Brake work can
be done at home, but someone at the work site has to be knowlegable in
how a brake system works. My strong suggestion is that you either ask
a friend who has that knowlege to sit with you or that you have a
mechanic do the work. Brakes are not something you want to have fixed
just part of the way.

Okay,

Thanks for all the responses!!

From suggestions, I gather that I should empty the brake system
first, and then replace the master cylinder. I can pump the new fluid
into the system after I install the new MC, correct?

That sounds like a good Idea actually. I was going to flush AFTER
installing the new MC, but I guess I could get some old/new fluids
mixed together that way.

Has anyone tackled replacing a Master Cylinder?

I am concerned about setting the pushrod freeplay. Any
suggestions? The honda manual has a special tool that is used, and
Tegger's method of MC changes (at his website
http://www.tegger.com/hondafaq/maste...ace/index.html) uses
an alternate and interesting approach as well. This would be my main
concern, as I wouldn't want my brakes to slowly lock on me while
driving, nor would I want them to not slow me down...<grin>

Thanks all...
