best way ever, will make a brake feel like new without even a complete bleed, get a syringe, screw your bleed hose into the lever grub screw end, remove the plunger from the syringe and put on your hose, fill with fluid and then simply pump your brake in and out and few times, flicking its good as well also do the tpa right up and pump it, i tend to pump it a good 10 or so times! release tpa pump a few more times remove syringe replace grub screw and you will have an amazing feeling brake that is full up so will feel even better, takes all of a few minuets and makes it feel amazing! hope this helps
what lever are you using?
