Well, brakes can be a long dicussion, because different riders have very different uses of brakes, very different requirements, and very different expectations.
Let’s start with maintenance schedule. 3 month for me, is a pretty decent life for bicycle brake pads. That is because I ride about 5000 miles in 3 summer months. I usually replace front brake pads every 5 or 6 weeks on my street bike, and they cost 35$.
Motorcycle brake pads are much thicker, and the average rider is not wearing rear pads. They are for motorcycle brakes of course, that are about 10 times the weight. Light weight performance always have a cost.
Brake pads are generally available with 2 different compounds: performance and endurance, and different manufacturers are making different conpounds. Performance are not lasting. In fact some are made to last one racing day, like racing tires compound.
