K1 rear brake

[fayeslane]

My K1 had a small rear brake problem, looks like it was dragging and generated enough heat to melt one of the caliper pistons

The only inkling I had was that it seemed to lose power and then come good (thought it was the fuel system). Stopped for a look when the ABS light came on and thought molten alloy on the wheel is not normal

Looking at various retailers the pistons don't seem to be listed. I am thinking about replacing the whole caliper given it's exposure to high heat -are the K1 rear ABS calipers the same as any other models? Specific K1 info ain't easy to find.

Same caliper as the K100 models (8 and 16 valve).

Check the fiche, here:

The part number is the same across the range.

Yep, disk will be replaced. Don't like the heat induced blueing or the resurfacing that occured after the pad material disappeared
