Hey, thanks Eddie. You’re right, the part numbers may reflect different pad compounds as both bikes are single front disc but the SCR needs more stopping power, being some 160 lbs heavier. Maybe it uses the same pads as your Super Tenere?
I want to use the SCR disc as it is floating and therefore I assume self aligning, unlike the SR400’s rigid disc that already has a slight runout creating a periodic scuff-scuff sound coming to a stop. At least the theory behind floating discs is they are more resistant to heat warpage. I don’t expect any difference in braking effort.
If changing over discs I need to be careful the loctited bolts don’t mess up the aluminum threads in the hub. Maybe a pre-soak in acetone will help as I’m not going use a torch to heat the area. I expect new mounting bolts will come with pre-applied thread locker?
I'm with you on the factory's pad compound choice for their respective application. But, why not put the "good" pads on both bikes? The organic ones may be slightly more expensive and if the organics slow the 400 down okay, they might be doing it to save a few $/yen per unit. Things like that
do add up with volume production. =)
I've changed out a few rotors, not too many, and the bolts are indeed held with locking agent of some sort. That said, once broken free with a bit of muscle on a good hex bit & breaker bar, they spun right out with a 3/8" air gun with no problem.
Maybe have a friend hold the SR's brake lever firmly and loosen the rotor bolts on the bike? Someone has to hold the wheel.
Why not let the bike itself do it? =)
Keep us posted!
Oh! EBC's FA179V is a another good metallic pad for the SCR/SC front. $33.20 from Dennis Kirk. Regular FA179s are Kevlar and a bit kinder to rotors. I had a set on a Transalp that lasted like 25,000 miles.
