Do you stop the turntable or let it spin while you run e record brush

Hi all,

Since I acquired and have been using the Luxman pd441 I realized that this table has a low torque motor and the plater slows down considerably if I apply the brush with the motor running.
Which does more damage to the unit, the motor fighting the brush or the electronic being turned off and on dozens of times during a listening session?  Thanks all with more experience.
