Oil was seeking past one of my brake puck seals. while researching what O ring to buy (MS28775-224) it was noticed that Cleveland had upgraded the 30-133 brakes installed in my legacy to 30-164. Both have a static load capacity of 1,260# and a load limit of 4,550#, but the new one has a kinetic energy capacity 289,000 ft-lbs rather than 192,000 ft-lbs. So I ordered an upgrade kit.

It seems the main goal of this kit is to thermally isolate the pads from the cyl with a phanalic between the calipers and puck. At first it looks like the amount of pad material had decreased, but looking closer perhaps not.

one nice feature of this upgrade is riviting is no longer required to change pads, so replacing them in the field is easyer.

so how does it work? as expected, there is no more stopping power, but the fade after 3 seconds of heavy breaking goes away. Never used in the real world, but cheaper than prop beta and lighter than blade counter weights.
