Hey folks, I was cleaning my Formula Bianco pistons the other day and managed to pop one out a bit far causing some fluid to leak out. This isn't too much of a problem, I kinda half expected it might do that and accept it as part of learning about the brake, just the problem now is that the brake doesn't operate correctly as the lever now moves nearly all the way to the bar. Obviously they need additional fluid and a proper bleeding now.
OK so I have a bleed kit on order which I should have soon. My main question is whether the simple syringe-at-the-lever method will be sufficient to remove any possible air bubbles from down in the caliper itself? Would any air normally travel out of the caliper and upto the lever naturally?
Another question is what is the small Allen key fitting in the caliper banjo for? I only see those at the caliper end. Is it for flushing fluid through the system or something? If I top up the stock DOT4 fluid with a different brand should things be fine, or should I be looking to flush them out fully?
Just some questions before I dive on em. I'm pretty good at most things mechanical though am not familiar with the ins and outs of hydraulic brakes. I have the manual though at a glance it doesn't appear to mention these details.
