Just puzzling 'cos this is done in aluminium in later VANS designs. Is there a reason why plastic on the -4?

Stuff in the rv-list archives indicates that Van may have changed due to a few people melting the plastic lines with extreme braking. Nothing documents whether this happened on a single landing or after repeated high speed taxi runs which will overheat brakes much more than one stop. An intermediate fix by some was to use 6" to 8" of aluminum line at the caliper, followed by the plastic lines. (It's perhaps worth pointing out that a few VeriEze drivers have actually melted/burned wheel pants with braking, but people still use FG pants.) A friend of mine (& a few others over the years) had a failure of the aluminum line on his -6A a few months ago. A section around 1/2 the circumference of the tube & about 1" long blew out on the outside of the big stress-relieving loop around the axle. There is now a 'movement' on the rv-list to convert from aluminum to automotive teflon/stainless braid hoses.

They work excellent and I no longer have to worry about them cracking.... -Mike RV-4 Flying RV-10 Building -----Original Message----- From: owner-rv4-list-server@matronics.com [mailto:owner-rv4-list-server@matronics.com] On Behalf Of Steve Sampson Subject: RV4-List: Brake Lines --> RV4-List message posted by: "Steve Sampson" --> Is everyone using the 44-NSR (plastic) brake lines per plans?
