Dealerships rip off customers all the time, no new news here.
My Kia has 91,000 km on the original front brakes. Dealer tells me the pads are now down to 3 mm and they need to be changed ASAP + rotors etc......... it's a safety issue.
I calculate I'm getting about 7,000 km per mm of wear on the pads. So no rush in my mind given that I drive about 2,000 km per month. I ask the guy at the service desk how soon should I get them changed and he says that I might have 40 - 50 km to go............ before they start scraping. Then goes on the tell me that if the pads wear down too much the caliper piston will wear though the pad and start scraping the rotor, meaning the caliper will have to be changed out................. Extra cost he does not want me to bear. Thanks dude, you're so caring.
Can you image a brake pad wearing to the point where the friction material is gone and the backing plate is also ground away to the point a piston is scraping against the rotor?
I asked him if the pad had a wear indicator that would scrape against the rotor and make a noise to indicate that it was worn to the limit. He claimed it did, but he didn't trust them, whatever that meant. I suppose I should trust him more than the wear indicator. Goes on to say the scraper could damage the rotors and they'd need to be replaced. Well, don't you replace them anyway I respond.
End of story is that I haven't replaced the brakes and will look for another shop to do them sometime in the new year.
