Re: fast rear brake pad wear
Few interesting points raised here.
I've mentioned on previous posts that the rear brakes are a bit sus. One post I mentioned my high rear brake disc temperature. As I only use the rear when I'm off road, never on the tar, (legacy of road racing so the linked system suits me) this is still a mystery to me. Even though others have done extensive tests and temperature readings, I still have the temperature disparity and associated rear pad wear.
The other issue is braking response. While it will pull up very rapidly when needed, the initial bite is not good (compared to a GS) and a good strong hand is required to pull up rapidly. This may be improved with different pads but with the associated increased disc wear.
My thinking now is there is a bit of a flaw in the system. I think the front & rear are fighting each other. I believe the rear has too much bite using the linked braking. As the front lever pull is feeding 3 calipers with the linked system I would expect a longer travel than with the rear brake used initially then the front brake applied. This is not the case, and as there is no servo assistance, I can only assume the rear caliper pad clearance has been almost eliminated resulting in drag & wear. I am still trying to sort this one out.
Finally, the rear brake adjustment in the clevis does not allow the pedal to move down far enough for me. The threaded rod contacts pivot. This resulted in the pedal being too high and having to lift my foot rather than just rocking my foot forward to apply the rear brake when off road. I have compensated for this by shortening the threaded rod but standard it was a problem.
BTW, the off road performance of these brakes IMO is fantastic. For hard braking I just use the front, & when standing and slowing or steadying just use the rear. Total confidence here.
