I know a handfull of us have had problems with mushy pedals after we do a DIY brake flush. I've heard that the dealerships use a specialty machine to do a brake flush. Anybody ever get this done their with any success?

 

Yes! I just had it done last week, it is worth every penny. The pedal is much firmer and has a stronger bite. You might find yourself stopping short the first couple times you break. Highly recommended.

 

Interesting. Never heard of a "special" machine for brake flushes.

 

They use a vacuum bleeder which is no different than having a buddy help you pump the pedal. Regardless, it helps especially if you havent done it in a while.

Is it possible that their bleeder and process is more "air tight" than the DIY, method? Also, don't they cycle the ABS system as well?

 

The DIY method has been known for years and it is a method I feel 100% confident in. To be honest with you, Ive used both methods and I have better piece of mind using the DIY method. (BTW, speedbleeders blow)

Cycling the ABS? Never had an issue on ABS cars, however you can still manually bleed ABS, like bleeding an MC.

 

I don't about any other dealership....

but at my Honda dealership, we use the BEST method for flushing/bleeding brake systems, as good as factory. We use a pressurized machine filled with brake fluid, which hooks onto the master cylinder, which evenly pressurizes the entire hydraulic system...you then pop open each bleeder valve and you got yourself a perfect flush/bleed.

WAY better than ANY DIY....and yes, there are "special machines"

 

Explain how that works. If you are adding fluid at the same rate you are removing fluid, what makes the machine better? Other than making it a one man job and maybe having it done quicker?

For the people who track their car and flush their fluid out between sessions, how does a DIY differ than your machine?

Im not testing you, I truely want to know the difference.

 

I've done both also. I like the DIY method more.

I'll take a picture for you tomorow....pretty much the same way they bleed brakes at the factory. Do you guys think there are 4 midgets near each bleeder and a 5th one pushing the brake pedal??? Besides, I bet most of you guys push the pedal to the floor, when it should go down MAX 1/2 way. Impossible to blow the MC seals this way too.

 

Well, the service manual says to start at a different corner. So, other than convenience and it being a one man job, its not different than a DIY? Right?

Only the new Honda mechanics do that. Most of us know what were doing.

 

Vacula Brake bleeder is what dealership service centers may use.

They utilize the above tool due to the high volume of brake/bleed jobs they perform.

Both methods achieve the same result, although one method is faster.

Thats what I was looking for. Thanks.

 

Here's the tank with a diaphragm inside...pressurized air(15 psi max) and brake fluid...


And the attachment for the top of the MC



It's the same as having constant pressure on the brake pedal...without having to pump. Open the bleeder and a constant stream of fluid pours out. Fast flushing and easy/perfect bleeding. Beats any DIY IMO

no. Vaculas SUCK the fluid out while the diaphragm style pushes it out...without potential for air leaks, like the vacula. We replaced the vacula with the diaphragm style...faster and better. My ITR brakes feel factory after 50k

 

We used the Vacula and had zero problems. Tools that pressurize the brake system are even better.

You're right, the DIY is tried, tested, and true for some but for others it produces spongy/mushy pedal feel.

I'm not an expert on how the ABS system works but from my understanding, it has its own lines and the system is closed when ABS is not in use. How do we get rid of the potential bad fluid in the ABS system?

That looks crucial. Is that available to the public and if so, how much??

I was looking for a commerical product that resembles this, but IPD's database server is down.

When I did my brakes I used this! Worked very well, easy and can be done by one person. No pumping the brakes

 

is it possible to pressurize the system too much?

 

The Vacula does work very good but there is a BG machine that sucks out fluid and pressurizes the master cylinder with air pressure to push the fluid through the lines.
We use both.

Tools that pressurize the brake system are a great way to introduce air into the system -

Gravity bleeding is the only way to go - https://honda-tech.com/zerothread?id=925064

I have never had a problem doing it this way, takes one person and about 30 minutes.

For a street car, it may not matter. For a track car, any air in the brake lines is very bad.

Looks suprisingly like my Motive bleeder:

Which gets the one man and four corner full flush job done in 30 minutes or less And absolutely No more mushy pedal.

you obviously have no experience using a pressure bleeder. It's hands down the most efficient way. You don't pump in air...you force in fresh fluid

Dude... SpeedBleeders fawking rock. I've had them on my R for about 4 years and they have never leaked and I bleed them bitches all the time.

However... and this is a big however... If I were to do it again, I would get the motive bleeder as you can just lay under the car and drink beer with a straw instead of getting up to pump the brakes.
