Hi -
I've never done my own brake fluid bleeding / flushing but I'm planning to start. I have the power bleeder and a bunch of fluid.
I swap out street/track pads when I go to the track, and I've done my own rotors. But the bleeding thing is going to be a new thing.

I think I've got the idea on how to do a flush. There are plenty of DIYs on that, and it all seems clear enough. What I'm not so sure about is a mid-flush bleed. Does anyone do that anymore? I'm thinking that I could do a bleed before and after a track event and do a flush once or twice per year, depending on how many events I do.

The big question I have about these bleeds is what to do about fluid. Do I open a new can every time and discard the unused fluid? If that's the case, I might as well just to a flush. Or, would I save the fluid from one can to use for multiple brake bleeds? If that's the case, do I dump it all into the power bleeder, and then dump it back into it's can?

Please let me know what you DIY'ers are doing for brake bleeding. Or am I crazy and should only be doing a flush?

Thanks
Jack

 

Jack, brake fluid containers seal up pretty good, so I wouldn't worry about using a new can every time.

Doing the bleed is a piece of cake.

Fill up the brake fluid reservoir in the car to the very top. Screw on your pressure bleeder with no fluid in it and pump up to 20psi or so.

Bleed each caliper like you normally would. I'd check the reservoir after each wheel to ensure the fluid is not dropping down to levels where it might suck air. fill accordingly.

Thats it.

 

20psi seems high to me if youre using a Motive brand pressurizer. 10-15 is what I do.

I agree the fluid will last a couple of months in the bottle. You could even put it in a zip loc bag.

 

I don't think it really matters. I think the porsche manual calls for 2 bar, so I don't think 20psi is damaging anything.

15 will be fine too.

 

Great info. Do you guys believe in those bleeder screws? They sure sound like a good idea

 

I also only use about 10 psi but what I ve done in past few times is I keep the reservoir full after each wheel and refill it and only use the pressure bleeder for pressure instead of filling that up. You have to be careful on the level but no big deal. Makes clean up easy and if a hose breaks on the bleeder (which has happen to many) there is no fluid leaking all over. Also doesn t waste any brake fluid. Just a thought...

 

Pointless with the pressure bleeder.

I've heard they tend to leak also

 

I've used the same Motive bleeder for 14+ years at 20psi and it has never blown a hose. After using it I run denatured alcohol through and that is about a 3 minute clean up. I put a premium value on my time and don't try to save a few cents by saving brake fluid; its like $15 a quart. Not interested in spending any additional time trying to bleed out air from the system or filling the reservoir 8 times per fluid change. But whatever works for ya.

 

Not saying the 20 psi will blow the hose. The hose will eventual blow at any PSI.... ask those of us that know. I guess mine is older than 14 years... Used it so long I can t remember, LOL.

 

I was considering replacing mine with this:

What do you think?

 

Interesting, so you keep the reservoir full how??
It is cheap enough to try.

 

I guess one would have to keep topping off the reservoir?

 

Reviews are all over the map.... some people may not know what they are doing, and you can t always believe what you read on the interweb. JKW911 you let us know if it works. I trust you.

 

Guys, when bleeding, your are not going through much fluid.

If you refill the reservoir once you'll be fine. All you are doing is getting the air out, no need to push 4oz out each caliper

 

Once you open it, it has a 6 month shelf life
