Is this airplane new to you? There is an ancient issue with "old" return
springs on the master cylinders. The "old" ones were too short and new
replacements were sent to you from Van's for free. Was this done? It may be
in the log books but probably not. Search the archives. There are certain
lengths the correct and incorrect springs are. This measurement can be done
with the springs in place, as I recall. Having brakes that work is a nice
thing.

Check a few things here.
bleed the system up from the bottom.
take brakes off the mount and see if the way your hose or line runs to the
caliper causes it to jam sideways in the slide pins. (loosen line and
tighten it so there is no sideload when you slide the caliper in the
mounting holes.)
polish slide pins with scotchbrite.
These are parker brakes right?
we havent even gotten to the fuselage yet, but im a mechanic.

Charles,
I had forgotten about this issue of the caliper binding on the slide pins due
to the brake fluid line side-load pressure. I had that happen on an RV7A about
9 months ago. The brakes did heat up a little from this condition while in taxi
mode. I believe we were dealing with the left brake. A quick dis-assembly,
cleanup and reassembly with a very light film of brake caliper pin grease and
we were done. We did go ahead and bleed both brakes at the same time since we
had a little grime on our hands.

Most likely is the pedal rocker pivots are too stiff and the small
compensating valve spring in the master cyl can't open, thereby pushing the
pedal back that last bit. (These are NOT the pedal swing pivots which allow
for rudder movement) After a bit they either bleed down, or the system cools
and reduces fluid pressure.
Check by getting the brakes to the stiff condition then pull back on the
tops of the pedals to force them fully back and see if that loosens the
brakes. (This also assumes the pedal rocker action has enough swing
clearence to let the master cyls fully extend.)
If this is the case the best fix is to loosen those pivots some as another
spring is something that could break/jam/whatever at the wrong time.
Air in the line would not cause this as the compensating port allows for air
or fluid to return immediately. Is also not likely to be gunk in the caliper
as that would probably not get better after a few minutes. The same would
also be true for the too tight pins that retain the floating calipers.
The one other option is the matco style parking brake valve could be not
fully opening both poppets thereby acting like one way check valves, if one
is installed. If the above test doesn't make it better remove the pants and
get them stiff, then open the bleeder for a tad and see if they loosen. This
will tell you if the P brake is holding the pressure on. (you could also try
working the P-brake valve when they are stiff and see if that suddenly
loosens them.)

| Subject: | Fuel Line Firewall Penetration Location |
--> RV-List message posted by: Dwight Frye <dwight@openweave.org>
I have a quick firewall-forward question. I am building an RV7, and DWG-19
shows a suggested location for the firewall penetration for the fuel line.
It shows a gascolator on the engine-side of the firewall in this location.
My installation will be a parallel valve Superior XP-360 with an Airflow
Performance fuel injection system, vertical induction, and NO gascolator.
For those of you who have similar setups (or knowledge of any similar
setups) can you advise as to whether the standard penetration location
is good enough ... or is there a better location based on the equipment
I intend to install? I assume that without a gascolator I should use a
bulkhead fitting at the firewall, and then go with flexible lines from
there (i.e. no solid lines to fatigue when run to an engine that shakes
like a wet dog). Correct?

| Subject: | RE: 81" pitch on O-320 |
--> RV-List message posted by: "Kelly Patterson" <kbob@cox.net>
I'll throw in my 2 cents, and some numbers, since I'm running a 6A with 81"
pitch.
Couple of specs: 9.2:1 CR, carb & Emag on a fresh O-320 rated 175HP @
2700RPM.
My performance is nearly identical to the 79" below on the O-320 160 HP,
except slightly higher speeds in cruise (~160kts or 195 MPH).
It runs about 2150 at WOT static runup, 2300 on takeoff, 2450-2500 at cruise
over 8000', 2600 in WOT 200-300 FPM descents.
In other words, it never exceeds the RPM limit except at lower altitude runs
(<8000') or diving.
Climb is 1000-1500 depending on wt. & density altitude. This is all done in
Phoenix where D.A. is about 3000'+ & solo I'm at 1500 FPM climb.
In return I get 7 GPH fuel burns, which is great economy, and even EGT's &
CHT's when WOT. I prefer WOT operation.
I would not change the prop unless I needed more climb rate, but have not
used a short runway where it is critical.
With this setup, a 3000' long runway is fine at 5000' DA & gross weight.
This combo returns about 750 FPM climb.
YMMV,

Dwight,
I have a similar engine & fuel injection system I am installing in my RV-8A.
With or without the gascolator (and Airflow Performance doesn't recommend
one), your fuel line is going to go from where it comes through the firewall
to the engine driven fuel pump via a flexible fire-sleeved line, so I would
think that the location shown on the drawings would be about right, if that
works with where you installed the Airflow Performance boost pump. In the
RV-8 there isn't much choice other than lower left side of the footwell for
the boost pump. Maybe there is with the RV-7.

My daughters both recently got Bose headsets for their birthday's,
so now we're a 4 Bose family, and it's time to sell my remaining
other ANR headsets.
My previous headsets, all 4 pairs, were upgraded with the
ANR Headset upgrades from http://www.anr-headsets.com/
and also beyond that, a noise reducing kit similar to the
Oregon Aero Hushkit. (I got the materials and did it myself)
In addition I installed Gel earseals like the David Clark headsets
have.
So these are very nice, very quiet, and good quality headsets,
and I would bet each pair cost me at least $300-350 by the time I
got done with them. The sound quality while listening to stereo
music is excellent, and both are Stereo intercoms with individual
earcup volume controls.
I sold 2 pair previously and have 2 pair for sale right now.
One pair is the Pilot Avionics P-51C Pilot Cadet's for kids:
http://www.pilot-avionics.com/html/html_root/juniorhead.htm
The other is a Flightcom 5DX:
http://www.flightcom.net/headsets/5dx-headset.php
with the ANR it would actually be closer to the
Classic ANR set though.
http://www.flightcom.net/headsets/classic-anr-headset.php
I was going to list them on ebay, but I thought I'd post
them here first in case someone from the RV community was interested.
I stuck them on my site at: http://www.myrv10.com/forsale/headsets/
