Just make sure that you get the cover sealed back up so you have no leaks after you remove it.

OK- again, I'm not asking about bore size. To reiterate, we already tried the 1" bore master. While the pressure supplied was slightly more, the amount of 'slop' from initial pedal application to caliper actuation was worse. The overall pedal travel was longer. Both CPP and Wilwood recommended the 1 1/8" bore for my application, and I am satisfied with the pressure it supplies. I am satisfied with the overall pedal travel of the 1 1/8" bore master, but I am trying to eliminate this 'slop' that is present from when you begin to push the pedal until the calipers actually function.

Since you are unwilling to discuss the operation of the metering valve, I only have one last question: I'm taking your last post to mean that the metering valve can be removed from the master cylinder without any adverse mechanical implications. When I remove the metering valve, will this require the system to be re-bled? Also, when I re-install the cover, how does it need to be sealed? Do I need to use RTV silicone or Teflon?

Thanks,

Matt
