Original Clevelands are marginal.

The original Cleveland brakes on the 10 are marginal, at best. You may only need them to work really hard once, and they won't. The fade really quickly with hard stopping. I needed them once. Suffice it to say Marco brakes were installed as soon as I got home.
George Happ at Matco continues to improve upon them as well.

Point taken. I was referring to the current options (MATCO, Grove, and Berringer) which I don’t believe include Cleveland so I should have been more clear in my OP.

I have the original Clevelands and agree with others, they are a bit on the marginal side, especially if hot. But I also think it’s unfair to invoke over-gross operations. Once you go down that rabbit hole there are lots of things that get ‘marginal’. |

Didn’t want to follow you down the rabbit hole, but there is engineering justification for increasing the maximum gross takeoff weight above 2700 pounds if you have extended range tanks. All the more reason to have adequate brake energy available for an RTO at gross weight.

What is that justification, exactly? I am installing ER tanks and am curious...

The very short answer is that additional fuel in the wings reduces wing bending.
Suggest you get a copy of Ken’s engineering report for the ER tanks and have a read. It’s pretty thorough and even so - not a bunch of engineer speak.
Ken is quite adamant about increasing only the MTOW and not the MLW.
