I'd give that a big 'yes'. If the pedals are a little tight, then the master cylinder can't relax enough to clear the port and let the fluid flow back upstream. I like your solution!

Matt, One other comment. Be sure that your brake pedals are not the cause of th e problem. If the brake pedal hinge points have been over tightened, the result will b e that the brakes will always drag. I've seen this on several RV's. The solution is to pull all the cotter keys on the brake pedals, loosen the castle nuts until the joint s rattle, and re-install new cotter keys. The internal spring on the master cylinders aren't very strong, and any binding of the peddle joints will result in the master cylinder plunger not fully returning to the relaxed position. This results in brake drag that can turn your disks cherry red... Your plane should taxi on tarmac with as little as 900 RPM's. If it doesn't, then your brakes are dragging.....

From: Dan Bergeron Good Morning: I had an early brake issue on my RV-7A; they were dragging/over heating, although never to the extent I saw smoke. The problem and the fix turned out to be simple. It's one of those things Van doesn't tell you. Problem: I had over-torqued the fasteners holding the brake pedals to the rudder frames and cylinder assemblies. My mentor, an RV three-timer, who also did the first flight on mine, saw the problem immediately: Solution: Loosen up every bolt/nut holding the brake pedals to the rudder frames and cylinder assemblies to the point where they are no more than barely finger tight; and I do mean barely, or even less. Obviously you want to make absolutely sure you have cotter pins securing the castle nuts to the bolts. The fix took me two sweaty, uncomfortable, frustrating afternoons working with a mirror in tight, inaccessible conditions. The problem disappeared.

Also, the RV-8(A) rudder pedals are quite different design that those on other RVs. The pad where the foot presses on the rudder pedal is well above the pivot point for the braking action, so if you press on the rudder pedal you will apply some brake pressure - the geometry guarantees this. I suspect that this design "feature" could contribute to excess brake heating if you do a lot of taxiing, even if you are careful to minimize the use of brakes. Some folks have modified their RV-8 brake pedals to address this concern. I am aware of two approaches: 1. Fabricate an extension to the foot pad, to extend it lower, such that the bottom edge of the foot pad is below the pivot point for the braking action. This allows you to push on the pad without applying brake. If you want brake you tilt the foot forward to push on the upper portion of the pad. 2. Use one long bolt on each side for the brake pedal pivot, rather than two short bolts. Push on the bolt shank to actuate the rudder without getting brake. The bolt shank is a fair bit aft of the pad on the top of the brake pedal, so you need a pretty good forward lean of the foot to get max braking. The amount of lean forward of the foot you need can be reduced by fastening something with some thickness to the aft side of the foot pad. Option 2 is the simplest, and is what I did to my aircraft. I found that I did not need to build up the thickness of the foot pad, as my feet were happy with the angle needed for max braking.

If you carry a second crewman during Phase 1 flight test, an accident investigator (heaven forbid) or an FAA employee who ramp checked you would have a lot of questions, and whatever your answers were, they probably wouldn't be good enough. One pilot was enough to do the test flying on most everything with an F at the beginning of the designation, including nasty beasts like the F-104. In comparision our RV's are pretty simple, so I think it's hard to legitimately claim that a second crewman is required. ----- Original Message ----- From: Ralph & Maria Finch To: rv-list@matronics.com Sent: Thursday, April 29, 2010 9:03 PM Subject: RE: RV-List: RE: Only Pilot on board during flight testing.

No. Solo flight only! IF you were to make that argument of a second required crew member=2C then the FAA may FORCE you to always operate the aircraft with a REQUIRED CREW o f TWO (2) and NO SOLO. I am sure that you DO NOT want to go there. I know I do not want to go there. Gary A. Sobek "My Sanity" RV-6 N157GS O-320 Hartzell=2C 2=2C346+ Flying Hours So.

From: Todd Bartrim If your aircraft is pretty standard with a standard aircraft engine, then I doubt you could convince the authorities of the need for a flight engineer. In my case I used an alternative engine, which my very experienced test pilot was very unfamiliar with, while I was intimately familiar with it, but vastly less experienced as a pilot (student). Transport Canada completely endorsed my plan to use a two person crew of a pilot and flight engineer, which went well. But they were clear that it wasn't usually accepted. IIRC, in most things the FAA and TC seem to be pretty close.
