Yeah the bigger surface area coud help with heat dissipation. On front brake pads are on whole disk height, on rear there is 0.5mm lip on inside but that shouldn't be a problem. On new bike I haven't had opportunity yet to ride with son on shotgun much. Just few rides but I haven't noticed much difference to magura in case of not enough stopping power. But thats +18kg on steep descends with dragging brake, you cant brake with kiddo like when i ride alone ON/OFF style, if i do that he wouldn´t sit on bike anymore .
So my guess is that lower surface pad area leads to higher temps and probably some oil leak?? Just trying to figure things out so i dont experience power loss with son on bike. I also saw mt5 set for 111e on bike24 some special offer which is tempting but thats like last resort. That + oak levers could bring magura+shimano benefits together kinda.
