Rear brake caliper problem! the rear's only have to be lubricated every 15k miles or annually. A manufacturing problem that should be listed on a recall problem to replaced with a redesign that does not require this lubraction. (please note: people and as myself do not know this, and do not do this. Therefore, the caliper becomes frozen, and the wheel is not braking when it should be. This is a safety hassard. The repair is a new caliper and disk. Conclusion: other manufactures do not have this problem.
