Began installation of fuselage brake lines. I've purchased the Bonaco stainless steel lines and had to figure out how they are incorporated into the system. It seemed I didn't have all the lines. Consequently, I called Bonaco and had a nice discussion which cleared things up. I didn't realize that their kit does not include lines from the firewall to the exit at the gear leg bracket. They stated that too much flexible hose line will cause a loss in pressure and result in mushy brakes. They recommended using hard aluminum line, per plans, for those runs. So, I began installation of the hard aluminum lines from the gear leg bracket to the tunnel and from the tunnel to the parking brake.
