Ok. Something really funny is going on here. And i've worked as a bicycle mechanic for a good couple of years in the past...
...My brake pads on my maggy martas wanted checking.
...i removed the retaining pin, removed the pads, pushed the pistons back into the caliper housing using a tyre lever.
...i replaced the pads with the old pads (as they had a ride or two left back in em!).
...i pumped the lever...
...i did it some more
And nothing happened. The brakes seem to have lost some fluid...the lever pulls to the bar?!?!?! What the **** is going on? It doesnt make any sense. I don't understand what could possibly be the problem. The pistons are both moving...they just seem to have lost some fluid.
