Poll for past cars:
Mini Cooper:
no squealing, did the brake work myself
Chevy Sprint: no squealing but occasional grinding noise
Mazda GLC: no problems
Dodge Avenger: brakes squealed a lot, and replaced pads every 18 months, rotors every 2 years.. major defect in "engineering". but it was released as a TSB after the warrenty had expired so the dealer was no help at all
Ford Expedition:
Occasionional squeal, when pulling a heavy load on the trailer
Chevy Trailbalzer:
no problems, but brakes a generally "softer" something you get used to..
Porsche Boxster:
brakes squeal all the time, due to the high metal content in the pads. Porsche's response, was "would you like quieter, lower performance pads instead????,, we didn't think so, we went with performance over convience"
Nissan MO:
no problems at all, the breaks are nice and firm, and I work them hard..
Edit: changed breaks to brakes..
