well the saga kinda continues ,
the chap i know managed to get seals remanufactured for me from the original samples , had to take a min qty off 3 each, caost £ 42.00 . came home and fitted the first set of seals and could hardly move the piston in or out , now im a rubber man for my work so you would think i would have know to not put a small smidge of grease onto an epdm seal but i did , started great . set up a spare caliper and disc on the bench . bled the system and brilliant so i left it and over the next couple of days and everythiing seamed fine , so i stripped it all down and reset it up with the proper caliper but when i went to bleed it the piston was solid and would not return ---bugger
after a bit of thought i managed to get the piston back out and the seals has expanded exponentianly to the grease i had used to lubricate them . so second set fitted and this time i used a little veg oil and the piston slid in and out with minimal effort but on bleeding the set up i still had no brake after 1/2 a ltr and was still pulling air through so i striped it down to descover that there was a small nick out of the front seal -----bugger didint spot it going on but maybe i did it , who knows
third and final set fitted , no veg oil but tried the piston in and seemed to be free enough , but after another 1/2 ltr and still pulling air through , bugger . bugger . bugger .
then brainwave fitted a syringe filled with brake fluid and reverse bled it . after a second a massive burp from the resivior and i had pressure ,must have been an air pocket . i would say that although i had used 50 gallons of new fluid the stuff that came up through the resivoir looked dirty but fitted it to the bike and no problems so far
no bugger
