Yes, I do know what the MEL says about brake temp ind. I also know a bit about the analysis required before items can be included in the MMEL.
No doubt the first chapter of your company MEL will state that the commander can refuse an aircraft with inop equipment, even if the MEL says it's a GO item.
If you feel so strongly that it is unsafe not to have tyre pressure indication in cockpit / wheel-well fire warning / brake temp ind. there is only one thing to do.
