To those with Shimano issues – how are you bleeding them? The syringe forcing fluid from the caliper into the master cylinder/funnel or the old traditional way (before funnels etc) and the same way automotive brakes have always been bled? ie drain tube into bottle on caliper bleed valve, fill master cylinder, open caliper bleed valve, squeeze lever, close valve, release lever, open valve, squeeze lever, close valve, release lever etc/repeat/top up master cylinder during process. Cable tie round lever overnight. Remove and ride in morning = hassle free brakes for years.
This has always been my experience with the older models and have not re-bled my 755 for probably two or three years now – do the newer ones just fail in some other way? Just struggling to see what there is to go wrong?
