Re: Can steel brake pads be used in systems designed for carbon?

We converted our 737 NG fleet to carbon. What other changes needed to be made aside from the wheels and brakes themselves? Did you need to modify the ABS system for instance? Regards, JetMech I'm sure there was a LRU change to the box that controls the anti skid. I was working line mtc at the time ...

Re: Can steel brake pads be used in systems designed for carbon?

I doubt it. The wheel itself is likely not compatible. We converted our 737 NG fleet to carbon. The old steel brake wheels could not be used if carbon brakes were fitted. The key ways that the brake rotors sit in were of a different pattern. For a few months we had to stock both spare wheels and bra...

I means shaped like a cross. Most notably the square Templar or Maltese cross. So in reference to an airplane it means the wings are very close to the middle of the fuselage and are roughly the same width as the plane is long.

I'm guessing that it tends to move the center of lift to far forward.
