jes42 Posted February 24, 2013 Report Share Posted February 24, 2013 Have just fitted an xblok front caliper to my evo. Can anyone give an explanation of the best way to bleed the system ? There is no bleed nipple fitted, just a small grub screw, is this normal or should there be a proper nipple ? Many Thanks. Quote Link to comment Share on other sites More sharing options...
djdenzil Posted February 24, 2013 Report Share Posted February 24, 2013 The xblock comes with a special banjo bolt, the grub screw is fitted to the top, without this it's impossible to bleed. U can pick one up from a well stocked trials supplier. Quote Link to comment Share on other sites More sharing options...
jes42 Posted February 24, 2013 Author Report Share Posted February 24, 2013 Thanks for that mate, excuse my ignorance but does this mean you bleed using the banjo bolt and don't touch the grub screw? What's the difference between the two banjo bolts? Cheers again. Quote Link to comment Share on other sites More sharing options...

jes42 Posted March 3, 2013 Author Report Share Posted March 3, 2013 HI, I fitted one and managed to bleed the brake to ALMOST as it should be but was struggling to get lever pressure. After asking around someone told me to remove the master cyl cap and just"flick" the brake lever enough to move the piston about 2-3mm and watch for little bubbles, sure enough the last bit of air came out and now have pressure at the lever and the brake is perfect except for a bit squeaky from fluid on the pads. The only downside is it took a good half hour or more of fiddling with the lever but it's worth knowing. Good luck with yours. Quote Link to comment Share on other sites More sharing options...
