This is the dumbest fucking lawsuit I’ve ever seen. Americans are too sue happy. I flew frontier last week and the people at the kiosk were repeatedly saying “make sure to size your bag. If it doesn’t fit, pay online because it’s cheapest”.
If you fly frontier and don’t read their policies you’re just stupid, not exploited. Go through their website and you’ll see the endless warnings about bag fees.
Just keep a close eye on your brake pads and learn to determine their remaining life. There shouldn’t be any issues unless there are other underlying mechanics issues with the bike. You will not overheat your brakes in a meaningful way just by pedaling.
This process is done intentionally on new bikes (called ‘bedding’ your brakes), although for disk brakes. Bedding rim brakes can have benefits too, like better contact patches.
