Brake Fluid

[Tool Pants]

The system hold less than .5 of a liter.

On our work on cars days I usually use 2/3rds of a liter, which includes the clutch.

According to the Bentley manual, if you have PSM then the PST2 is needed to bleed the brakes. In other words, not a DIY job.

Would you mind explaining PST2 and why this is not a DIY job?

From Bentley: "Brake bleeding on vehicles with ABS/TC 5.3 and PSM requires the Porsche System Tester 2 (PST 2) to activate the valves in the hydraulic unit for proper bleeding."

I believe the PST 2 is software/hardware. I've never seen it for sale, but have heard it's in the thousands of $.

Thank you. I will investigate. I had hoped to do it myself.

That's because you're a pro by now. We newbies need the full two cans

Well, I did figure out a way to bleed a caliper twice as fast....

What's the best brake fluid to use? ATE Blue?

ATE blue is what I used and I'm very happy. I think they also offer an ATE gold so that way you can alternate colors. This way you know when the old stuff is flushed out.

For a normal brake fluid change you do not need a PST2 if you have traction control or PSM. You do need it however if you are changing the fluid because those components have been replaced.

The manuals also say you need to hold down the clutch pedal when bleeding the clutch. You don't need to do this unless you have just replaced the master cylinder.
