I did they stated that they have asked the manufacturer of the polisher not to do that several times because of instances like this, they also stated that if i replace the brushes on my own it would void my warranty on that polisher . Apparently they dont want you changing out parts of there products.
Good news is I figured it out , I was using a 4" backing plate with 6.5" pads. I changed the backing plate back to the original 6" plate and it hasnt bogged down since. I dont know if it just mere coincidence or what ?
