To test bearings & braking I would jack up one wheel at a time and check for just a very slight wobble in the bearing and then pull the emergency brake cable to engage the brakes. Then spin the wheel forward to determine how far it rotates with the magnet energized before the brakes apply. Never got over 1/2 turn before the brake shoes stopped rotation by hand.
No need to have things so tight you get unneeded friction and heat.
