So back a couple months ago I swapped out the OEM semi-metallic HH pads on my 2014 Zero S to organic pads, and it greatly improved the braking modulation; with the OEM pads the bike had very abrupt braking, almost an on-off switch. So I was singing the praises of organic brake pads until this thursday when they suddenly lost 70% power while I was passing a car into a steep downhill going into a hairpin turn. I made it out the other side without going down, but this happened without warning. I had overtaken the car and was pointed downhill facing the hairpin and I swear pulling on the brake as hard as I could felt like I was getting barely any braking.
If there is a lesson to learn as far as my riding, it's that I have gotten so out of practice at using my rear brake that I didn't want to risk it in the second I had to react; it's actually a slight left going into a hairpin right, and I didn't want to slide the rear with the bike leaned over. I am now practicing using my rear brake. On the other hand, my trackday experience definitely gave me the confidence to quickly throw down the bike into the hairpin at a speed I would never consider doing intentionally on the street. The tires stuck, the turn was banked and I didn't even scrape the peg. Two minutes later the brakes were back to normal...
This spot is near the bottom of a 2000 foot windy downhill, so I was heating up the brakes going down, and the final stress that threw my brakes over the edge was definitely the fact that before passing the vehicle, I had to do a full-on emergency brake on my first attempt at passing this guy, as he went into the oncoming passing lane to block me! This is a very safe passing spot, and I pass cars every week on my normal morning commute on this section of road (this is Kings Mountain Road, for those in the area...). I have gone over 2 months with this brake pad setup and have never noticed any fading on the street. But I think I had the OEM pads on for my trackday...
Anyways, I did want to post this here as I previously recommended organic brake pads as a good solution. I definitely take that back: it was one second they were fine, and the next time I pulled them, they had stopped working--in a very bad situation. There has to be a semi-metallic pad that has both better modulation and does not suddenly fade like this. So I will be experimenting with that and will report back here.
