Soft brake pedal after fluid change

Had local shop replace brake fluid with high performance fluid (higher boiling point) for my upcoming trip to the track. The result was a mushy pedal (longer travel to engage brakes). I immediately pointed it out and the owner road tested the car. He said the same thing happened on his 360, he bled the system multiple times and no change. His ultimate conclusion was that replacing the old fluid actually made the calipers work better (more fully release) and thus the increased travel.

The brakes do not pump up, so from another post, apparently that means there is no air in the system? The pedal does not slowly depress, so apparently no leak?

Not sure i trust the conclusion of the shop, so looking for input.

Thanks in advance for your help

Every day I look around, and if nobody is shooting at me, it is a pretty good day.

Taz is spot on- bleed the master cylinder, make sure you do BOTH bleed points on it.

Excellent, problem solved! FYI, for the newbie, I removed the drivers side panel and the panel at the back of the trunk compartment to access the bleeder nipples. Very easy.

As always, great advice!

Morton- Every once in a while, I get lucky. Eddie actually knows what he is talking about.

Guys , when you do a brake flush or open the brake system for repairs. You need the Factory SD2 to bleed the system properly. You will never get all the air out. You may think it works properly but it's not.Every car that i have done , I need the SD2 to do it properly.
Good luck.
Alex.
