rear shoes on 2010 yaris

[thomas667]

Ok so i replaced the rear shoes on my yaris. which I have done on all my cars with drums.So I go to firestone to have them to bleed the brakes and check the adjustment on rear brakes .Well the service adviser comes to me and says there is a problem.... This what he tells me being that I replaced the rear brakes and didnt adjust tem I blew out both wheel cylinders which I never heard of doing that from not having the proper adjustment on the shoes.I drove the car for two days and the brakes were fine.... Is he bullshitting me because I never had that happen to any other of my cars before.... anyone know if he is taking me for a ride ??? Besides I drove the car there its about 5MI I think i would have noticed the brakes fading. Any thoughts would be appreciated thanx FTD66
