.060 Over
I did the bleed on my 2020GT twice before i got it right.. Seems the factory is leaving a lot of air in the portioning valve block which is at the high point of the system.Sounds like they did not do the job right the first time.
i bled the rear brake using only the foot pedal on the first two attempts, and it worked for a while till the air found its way back up into the block. The third time i used
a small vacuum pump on the caliper bleeder, AND used the rear brake pedal at the same time and got a lot more bubbles .. Took over half the bottle of DOT 4
to finally get out the remaining air.
Brake is hard as a rock now.
