According to the shop manual, when bleeding brakes on cars with PSM you should have a bleeding pressure of 2.0 Bar (29.4 PSI). Is it necessary to use this much pressure? I have a motive bleeder. Thanks.

No, i am talking about PSM, I am just reading the shop manual and it state scars w/o PSM should be bled with 1.5 bar of pressure and cars with PSM should be bled with 2.0bar of pressure. I read the rentech DIY as well and thats why I was asking. If everyone has done it using under 20psi that is the route I will go. Thanks.

I bleed all mine at 1.5bar or less (usually 1-1.25bar) regardless of PSM or not. I have zero issues having the fluid flow properly. Would be interested to hear to reasoning for bumping up to 2bar on PSM cars.
Can you scan and post the shop manual page(s) you are talking about?

I did it the old fashion way many times, didn't notice any difference with my brake performance. But now I think about it my PSM does not react as fast as before... maybe 0.01 seconds slower. :P
