And the needless expense of new bearings every time you change the discs. I reckon something around 3 sets of discs to each set of bearings needs changing for your average car. So that would be two times you'd be chucking away perfectly serviceable bearings
Can I be your mechanic?!
The cost of bearings are pretty insignificant, IMO. You just have to look at it as preventative maintenance on the bearings
In all seriousness, though - I'm sure most people can change a set of discs and pads themselves, but very few have access to a press - it'd be cheaper for people like these to pay extra for discs with bearings than it would to take their car to a garage to have the bearings done when needed.
Or people like me, who have access to a press but absolutely ****ing hate messing around with pressing bearings.
