The most expensive of disc brake pads we’re aware of, the 4 Seasons are meant for just that – one pad for all conditions. They work well and were powerful and noiseless once bedded in, which they did pretty quickly.
There’s quite a premium to pay over other pads offering pretty much as good as performance. The Swiss Stops would have to really prove themselves extra durable to help justify the cost. No bedding in instructions were included either.
