I bought a little vacuum pump
and Im going to siphon my brake fluids.

i think for now all i wanna do now is vacuum most of the fluids
out of the reservoir and fill it in,
so it wont be a 100% flush.

my question is whats the possibility i hurt my master cylinder?
caz I heard lot of time u change brake fluids u could brake them..

any tip is appreciated

 

I don't think it should hurt the master cyl. any. I do brake flushes at work all the time and never had a problem with that. But I've never done one on a 3rd gen, so it might be a lot different. LoL

 

It's usually a good idea about every five years or so. The old fluid can become contaminated with dirt, water, and debris from the system. I'd be surprised if you caused any problems unless something went very wrong with the process.

 

As long as you NEVER let the MC go dry you will be allright.

 

cool, ofcourse i wont dry it.

just incased im going to leave a little fluids on the very buttom
of m/c and put new one in, so it'll be a little mixed with new dot3 and old dot3,

that shouldnt be a problem either right?

thanks again!

 

Just keep the MC full as much as you can, all the old fluid will leave the MC as you bleed it.
