Just thought I would share. I am fitting a new disk and pads to my 2001. I would have rebuilt the caliper, but the supplier forgot to order it. When I pushed back the pistons, I noticed that there was seepage from the hose connecting the reservoir to the master cylinder. I believe that this was the main factor to 'loosing' my rear brake continually. The hose is most likely also the original, but it seems odd that there is no clip to pinch the hose onto the fitting.
