Brake Life Expectancy

I've had 269 full-stop landings in my Tecnam P92 Eaglet since the last brake pad replacement. Is this good, bad or average? I didn't notice any issue with the brakes but the A&P doing my conditional said they were needed.

My first set of pads lasted around 300 landings , the second between 500-600 landings ...pads were obviously exactly the same , I just got better , landing slower and not dragging brakes while taxing.

PS.
Now , this is not exactly comparable anyway .. now that I think about it ,if my hangar was located in a different row , I would almost never need to use brakes since there would be no incentive to “make the exit” ...

Most mechanics who are not familiar with the Marc brakes will say they need replaced. The minimum thickness for the Marc pads from the P92 MM is 2.4mm. That is way less that the normal pad thickness that aircraft mechanics are used to.

Most people who are familiar with the Marc brakes will agree that they should be replaced regardless of their condition. :lol:

If it is an option to switch. I know it is with Flight Design. Honestly, never really had an issue with the Marc brakes, but they do require different care and feeding. That is until you have replace other than consumable parts.

OK - it's been a while since I literally laughed out loud, but I did on that comment! Too funny!

To be fair, the Marc brake pads on my Sky Arrow still had some life left in them after nearly 600 hours and 14 years. Lots of local lights with a fair number of touch and goes - somewhere around 800 landings if my logbook is correct. I don't abuse them, but don't baby them either. I replaced them proactively not too long ago with a lightly used set a forum member gave me (Thanks, Andy!).

Anyway, no complaints about the brakes, as I've stated before.
