Title: Brake Fluid Flush
Post by: gargantula99 on January 19, 2011, 09:14:24 PM
Does anybody know of a "How To" on this?  Preferably with pictures.  I can't seem to find on anywhere.

Thanks!

Suck it out of the master cylinder with a vaccum pump. Fill the master cylinder and bleed the brakes until you have clean fluid at all four wheels. Start at the most distant wheel from the master cylinder, and follow the normal bleeding procedure

There is actually a bleed sequence on newer Hondas. It actually goes LF, RF, RR, LR.

What Mike said, with Thien's sequence.  I found it odd too, but the Honda service manual says to start at the line closest to the master cylinder, and work your way to the furthest line from the master cylinder.  I'll double check again on Sunday when I get back to MA.

That is an odd sequence. It used to be the reverse. BTW Tim, I fixed who's sequence you mentioned.  ;)

Sorry for bumping an old thread, but I have some questions.

As far as using the vacuum pump that Mike said, I could rent these at Advance Auto or Autozone, right? Would I have to vacuum every bit out from the master cylinder?

I was planning on using a turkey baster to suck out as much as I could out of the master cylinder, then top it off with the new fluid, and then go around to each wheel and start bleeding. Is it absolutely necessary to have the hose going from the bleeder valve into a bottle that has some new brake fluid in it? It seems kind of like a waste to me. I know it's so that air doesn't get sucked back through, but I figured any kind of liquid would work, even water.

Which way would be easier to do?

Also, how safe is it to have the car on four jack stands? I'm still a little afraid of the idea, but having to take the front wheels off, bleed the brakes, put them back on, then do the same to the rear will get kind of old. I don't want my car to slide off the jacks when I'm trying to put the rest on or something. That would suck bigtime.

Thanks in advance.

I do what you were planning to do.  I use a turkey baster to take out old fluid from the master cylinder, fill the master cylinder with new fluid, and start bleeding.  I monitor the master cylinder to make sure the fluid level does not drop below the minimum line to avoid letting air in the system.  I continue to do this until all 4 brake lines are filled with only new fluid.

As for the brake fluid into your  bleeder bottle, you could use old fluid too.. just dump the old fluid in your turkey baster into the bottle.

But honestly, I don't keep leftover brake fluid.  Brake fluid is hygroscopic, so if i have leftover fluid, i typically get rid of the rest.  It's not like I'll be using an open bottle of brake fluid the next time I bleed my brakes.

You can use the vaccum pump to bleed your brakes also. I think I bought my vaccum pump at harbor freight for like $8.... Your car will be fine on four jack stands as long as they are at the right spots.

Alright thanks for the info. As far as right spots go for jack stands, I was thinking of the four points under the rocker panels (right behind the front tires, and right in front of the rear tires). Is that going to be okay?

It will be okay but, its even safer to put them on the sub frame(for lack of a better term). Basically just look for solid metal and put them there. It's tough to describe.

I put the jack stands on the sub frame just because the jack stub are occupied by the jack

I usually jack up the front of the car at the tow hooks, so I can put the jack stands at jack points by the rocker panels.  In the back, I jack it up on the sub frame.

ahhh fucken A my bleeder valve are stripped... So I bought speed bleeder valves. That way I can do it on my own... Piss me off though.

that's good I saw this thread I will be doing mine as well. so the sequence are correct from the top?


Title: Re: Brake Fluid Flush
Post by: MyNameIsThien on May 09, 2011, 11:39:43 PM
Yes it is. Left front, right front, right rear, left rear.

When only replacing front pads/rotors, should i bleed the rear as well? Or is ok to only do front?

You are suppose to bleed the whole system. That way you don't get any back flow from the old brake fluid mixing in with the new brake fluid.
