What is everyone seeing as far as lifespan on your brake pads/rotors? Mine recently started making a grinding sound on the right side when taxiing and shuddering when brakes are applied to make a right-hand turn. I inspected the rotors and found them not very smooth with visible grooves. I'm flying to the Beringer factory in Greenville SC tomorrow to pick up new pads and rotors. (FYI - $310 for the parts doing both sides)
Here's a pic:
PS - I'm right at 215 hours on the Beringers.

Have you spent any time at grass fields?Is there a lot of sand or accumulations on the taxiways or other pavement? Do you have wheel pants? Especially when the grass is wet with dew, the tires will sling sand, dirt pebbles up into the wheel pant and the stuff gets deposited on the rotors and calipers. Unfortunately it dries on the brake components then the severe abrasion of the rotors starts at the next landing. Yours looks like a pebble or two got jammed in.
If not, the steel on the rotors may be soft. Not necessarily dangerous, just a high wear item. Designing in soft material in the rotors is an old and easy way to prevent squeal and shudder, while increasing grip. On high end german cars, this is standard practice. Had a set of front rotors that lasted only 50k miles.
FYI, my Tecnam has spent its entire life (650 hrs) on pavement and the rotors are smooth but worn with light scarring. On the other hand, my past taildraggers always had beat up rotors.
Hint, see if it is possible to turn the rotors. Most discs don't have enough meat, but maybe yours have some excess.

Thanks for the reply. We replaced the pads and rotors today. They were worn down to metal on metal. There is a way to check the pads. New ones have a line down the middle. This can be seen from below the wheel pant. Once the line is no longer visible, it is time to change the pads.  |

The one on the right shouldn’t be used. Just sayin’. 😁

I see, what’s happening. I have a solution to your situation, was to use brake cleaner every other flt....... small metal particles don’t allow the pistons to move back after brake application, and it get worse the more you apply the brakes. I did just as you are doing I replaced the rotors and pads, and most important put new seals on the pistons.And most important DON’T OVER APPLY THE BRAKES be as gentle as you can while braking. This has worked for me, I hope it helps you......
