yeah,
front is floating
rear is fixed
u need to turn the rear caliper for it to go in.
i just used a pair of needlenose pliers, turned it about 4 times.
MAIN THING!!!!
u have to align the caliper correctly.
(i didnt do it at first)
what i mean is:
the rear caliper has 2 slots.
these slots are for turning it, AND are there so the caliper clears the little bump on the brake pad that holds the metal cover.
(u'll know what i mean when u see it)
MAKE SURE U ALIGN IT CORRECTLY, otherwise u will get uneven pad wear.
