Brakes getting weaker?

[brushlessboy16]

oh alrighty, umm check all the leads to and from the esc for loose or broken connections

The power's not cutting out or anything, so I doubt it's a short or broken connection.
I tried raising the brake power to 50% with no real effect.
Raised the motor start power from low to medium and then brake power to 80% and it seems to be stopping like it used to at 40%.
I guess the motor's just starting to go. Either that or the speed controller.

could the motor have heated up too much some time?

ive noticed that if you demag a motor u get way less brakes... but your temps seem ok?

also, double check your radio... i felt so stupid after i realised why my brakes were not working

Yeah, I think I mighta demagged the rotor.

Awhile back, I "popped the can" and the rotor spun a few revs while the can was open and the rotor shaft was at a slight angle, so I am thinking this may have damaged the front bearing or the rotor/coils themselves somehow.

After running it tonight, the brakes faded and are like they were before I boosted the braking force again. I also noticed that while temps were fine for the most part, the rotor seemed much hotter than any other part of the motor. While I'd think this is typical as that would be where the heat would logically be highest, it is my only explanation.

Prior to this condition starting, I redid the battery harness and added a capacitor to the power leads going to the MM, so really the cap is the only other thing that may be any different.

The brakes faded rather suddenly and at the same time, I noticed way more cogging at lower throttle positions than is typical.

Seems almost like I heated the rotor up to a certain temp and once it crossed that threshold, the magnets just kinda went. Still works, just not nearly as well.

The only other thing I could imagine it being would be the cap or the ESC if it is starting to die on me.
