Product review (1 stars): This is not a p/n 195518 replacement
Despite what the product description says, this is not a direct replacement for the stock p/n 195518 pads.  The stock pads are 2-1/4" in diameter whereas these pads are 3" in diameter.  On the other hand, I had no problems with getting an RMA number to return these, and my money was credited to my credit card very promptly.
