Good Morning All
I have stripped my front brake calliper down as the brake lever had no resistance, The fluid was nice and clean when it came out when I disassembled and the front hose looks fairly new which makes me think someone has tried to bleed the brakes before .
I replaced the Pads, calliper seal, new white nylon small washer & new fluid, I have checked the master cylinder assembly by putting a blank on the brake line and squeezing the brake handle which comes up hard

.
I cleaned and lubed all the parts ready for assembly, Reassembled and bled the brakes used the standard method of a bleed tube & still very spongey so tried it by drawing the fluid through using a syringe and they are still spongey
My question is the piston fitted to mine is the hollow version on one end I assume that the chrome machined end fits into the calliper with the nylon washer and the hollow end faces outwards towards the brake pad Should there be a slightly metal domed part that goes over the hollow end of the piston that then touches the pad as the CMS web site IPC appears shows this part. ( no good IPC pictures in Hayes Manual

)
I am sure this question has been asked many times before sorry to repeat it again any help would be gratefully appreciated
