I recently went to Mavis Tire to have a "free" tire rotation after putting 6,000 miles on tires I bought there a few months back. When they removed the tires they said they would do a brake inspection as a courtesy.
The assistant manager told me my rear pads were worn and would need to be replaced. I let him know that Mavis had done my brakes and the pads were under warranty. He then tells me the pads are worn because I need a brake caliper. I told him to give me a new set of brake pads that I will change myself and do the caliper if need be, put the tires back on my car and consider me to be a past customer and tell my friends and relatives never to use Mavis as they are a bunch of crooks looking to sell people stuff they don't really need.
As it turned out my caliper was fine and the brake pads they gave me were ***. I will never set foot in another Mavis store as long as I own a motor vehicle.
