After all of the painting, I started assembly of the rudder pedals and brakes. I punched the hole in the firewall for the single brake system and then decided to go with dual brakes. I lowered the reservoir from the dimensions in the drawing and fabed a doubler with nutplates for easy installation/removal. I had to buy a new set of master cylinders for the co pilot side. They are matco brand and the pilots side are cleveland's. A new set of cleveland's were just too expensive for the first officer. He should be happy just to have brakes...Oh yeah, I fabed the fuel vent lines and temporarilly installed them.
