PSM and brake fluid flushing

[mikehkang]

I have a 2001 base with the PSM and I want to flush the brake fluid.

Has anyone else do this as a DIY?

Thanks in advance.

Yes, pressure bleeder. About half an hour after you do it once. Raising the car and taking off the wheels is the hardest part. Many posts, do a search.

+1 on San's comments. I have used bleeders over the years, but holy cow the pressure bleeder from Pelican... what took two people and about an hour and a half to less then 20 minutes. Once you use it you will never look back...oh, buy the universal adapter as you can do any other vehicle.

Thanks for the prompt reply San Rensho and Eric.

What concerns me is the following description from Pelican.

"For cars with traction control or Porsche Stability Management (PSM), you need to use the Porsche System Tester 2 (PST2) in order to activate the valves in the hydraulic unit during the bleeding process. If your car has a “PSM off” switch on the dashboard, then you will need to go to a shop that has a PST2 so that the brake system can be bled properly."

I've also read other instructions that say, while not ideal, I can flush PSM equipped car without the PST2.

SR and Eric,
Do your cars have PSM?

Also, yes, the power bleeder IS the way to go.
Perhaps you do the same but I don't fill the power bleeder with brake fluid.
I use the bleeder to generate pressure and fill the reservoir in the car.
While this method takes a little more time, I always have my power bleeder clean.

I flushed my '06 with PSM with no issues. The consensus is as long as it's just a flush, and you don't get any air into the system, you don't need the PST2. The small amount of old fluid that is left will disperse in the new fluid, until the next flush.

Mike, sorry I missed the fact you have PSM so I don't have any advise on that.

Thanks.
I am going to do it now.

How many liters did you use?
The Pelican lists 3plus qts or almost 3 liters and I am guessing that with PSM.
Do you need less if you ignore PSM?

No problem.
I love your bike.
That's you riding in the picture, right?

I order 3L of Super Blue, but ended up getting it done with every bit of 1 L, including the clutch. But it's best to have some extra, just in case. The Blue color is great for telling you when the old fluid is out. BTW, be carefull with the clutch bleeder, it seems to be made of plastic.

Plastic!?!?

It is possible to use boxed 9mm or do I have to buy a flare?

Thank you for the prompt response.

I was able to use the box end of a combination wrench.

Yep, that's my old race bike (2000 GSXR 750) turn 3 and Pacific Raceway from last year. God I love that track, short, fun, fast and some wicked off camber corners.
