Uneven MATCO Brake Pad Wear

Thanks for your reply.

From your feedback, it seems that the robust solution to keeping the brake caliper centered on the brake disc so that brake pad is even is to use the braided brake line. The braided brake line only applies a small force to the brake caliper.

Further, I would suspect that the braided brake line would allow the inboard floating brake pad to be removed with the wheel still installed and not need to readjust the aluminum brake line to get the caliper centered again.

I installed Aircraft Specialty Flightlines Braided Brake Lines four years ago. I did this mainly out of necessity because I fly from a grass field. Tall weeds will impact the soft aluminum tubing that is exposed forward of the landing gear and cause damage to the tubing....

I chose the Teflon over-sleeve option and it has worked very well. If you are trying to achieve uniform brake pad wear…. I don’t think it’s possible. The braided brake line is rather stiff and can easily influence the brake caliper. The OP has 0.025” difference in wear pattern and I’d say that’s doing pretty good….

Because the airplane has a free-swivel nose wheel, it is imperative that both main wheel brakes work effectively 100% of the time.

You can have a real bad day if a brake locks up, fades, or fails….
