Squidgy brakes
 

Oh dear, another problem with my Amazon. Just as I start saving for alloys courtesy Mr Barrett, suddenly I'm suffering from erratic BRAKES...single circuit with remote servo, but really unpleasant pedal; sometimes very sensitive like a citroen i.e. standing on nose, sometimes there is hardly any pedal, just travel(very scary that one)and at other times lots of pressure is needed. The pedal also pushes back at times. The brakes have just been bled, I checked the rocker cover to servo pipe for splits etc, but that's about as far as dare go. Oh yes, it has synthetic fluid. All a bit'there be dragons. Or trolls. Any suggestions, helpful advice and cheap(please) solutions gratefully received. Cheers.
