Hi. Today I had my first encounter with brakes. It was just on my kx250f so I wasn't worried about giving it a go with no previous experience whatsoever. Long story short, I whipped off the pads and got the new ones in with no problems but on the test ride the brake barely worked at all. I don't really see how air got in the lines but i cracked on with bleeding. I bought this little one way valve ages ago in preparation of this day arriving so thought id give it a go. I slapped it on the nipple, undone it and then started pumping and as soon as the reservoir got low I topped it up. By the end I had a constant stream of fluid going in and was pumping the pedal at the right speed to stop it overflowing. A few mins later i closed the nipple, tested the pedal and had a rock solid footbrake with no drama whatsoever. Have I discovered some very simple but super effective way of bleeding brakes or is there something very different when bleeding brakes on the zx?

Thanks

Here's the valve

when the system is empty it a fuck of a job to get it all to prime up to get pressure

Ah, because there's nothing but squishy air in the lines so it doesn't want to go through. Makes sense. I knew there must've been something I wasnt seeing

and on a kx250 you only have one line feeding one caliper. super easy to bleed. when you have 2 to 4 lines feeding two separate, larger calipers, it can be a pain, especially from empty. Ski

Ah ok, but im guessing having the one way valve makes it 100x quicker than opening and closing the nipple?? That must take FOREVER. I just sat there pumping the brake. Jobs a gooden
