Hi,
I have just done the first taxi trials after completion of my RV-7.
Everything is great, except that I find the brakes to be very innefficient.
There is no air in the lines, I've bled the lines very carefully and the pedals are quite hard to press, the course at the top of the pedals is about 1/2 inch or or slightly more, both feel the same.
Also I have installed a Parking brake valve.
Trying to stop from a speed of less than 10 Knots takes probably 30 to 40 feet when braking as hard as I can.
With brakes applied I the plane doesn't move until I run the engine past 2000 RPM (195HP with constant speed prop), so I think that's good.
I'm a bit confused. The brakes are holding well for engine run up but can't stop the plane quickly from taxi speed...
Any idea why?
Thanks,
Alain.
