Hi everybody,
Couple of questions,
Rt1200 2011, one of the pistons in the right front caliper is stuck , while the other 3 are all the way back. The brake reservoir top is open but I still cant push that problem piston back. ?
Second question, shouldn't the ABS sensor on the front wheel just pull out when the small screw is removed!. ?
that also seems to be stuck.
Thanks

#2, yes the sensor should pull out with maybe a tiny twist to break it loose.
#1, You need to do some research on how to rebuild a caliper, get a kit of new seals and possibly pistons, some connection bolt washers and rebuild your caliper. Sounds like dirt and or corrosion has taken hold. Group of parts #10. It might be cheaper to find a used but good caliper. I personally would do both calipers in front at the same time.
