trials hoe Posted December 29, 2012 Report Share Posted December 29, 2012 yeah, air will always go to the highest point. if your lever is facing down slightly (i'm assuming you mean it's in the same position as how you will have it setup for when you ride it) a bit of air will stay at the piston end of your master cylinder in your lever.

Ok thank you! I hope this works. Back in a few Quote Link to comment Share on other sites More sharing options...

dannytrialskid Posted December 29, 2012 Author Report Share Posted December 29, 2012 (edited) Guess what.. didn't work. I got a video of it here. The first bit you see there is still slack. The levers are facing up. On the front brake there is a little slack. The rear which I am showing in the video is slack and then when I tighten up the tpa, notice there is a lot of turning! when the tpa is tightened enough so there is no slack when i press on the lever the piston gets stuck. when the you cant see anything on the video i am pushing the pads back in to push the piston back out. then i push again to show it still happens and then when i push the pads in for the second time i press the lever a 3rd time and the lift the lever and the piston pushes itself back out. i keep doing it and it does the same thing and then it just stays stuck again requiring me to press the pads. wtf is going on? https://www.facebook.com/photo.php?v=10200211511879464 p.s excuse the sounds and shit floor, currently renovating my house Edited December 29, 2012 by dannytrialskid Quote Link to comment Share on other sites More sharing options...
trials hoe Posted December 29, 2012 Report Share Posted December 29, 2012 is the piston in the lever all the way out when you're bleeding it with the tpa unscrewed all the way too? looks like a sticky piston in the vid, but slack in the lever will be air in the system. have you sanded the piston its self down a bit to see if its contributing to the problem? if the slave cylinder pistons are all the way out when you pull the lever they can stick too. with the lever angle air could still be getting trapped in there, try tilting your bike over a bit on its side a bit (so the end of the lever blade is lower than the bleed bolt if you know what i mean) Quote Link to comment Share on other sites More sharing options...
dannytrialskid Posted December 29, 2012 Author Report Share Posted December 29, 2012 i seriously have no patience anymore. none of this crap makes sense to me. Quote Link to comment Share on other sites More sharing options...
trials hoe Posted December 29, 2012 Report Share Posted December 29, 2012 which bits are making no sense? when i'm on about lever angle i mean like this - imagine the black line is the fill level of the fluid, fluid will still come out like here in no air in the system but it can still collect above the line in the cylinder. you need the lever at the angle below to avoid this i know you're using 05's but the principle is still the same.

customrider-Rhys Posted December 29, 2012 Report Share Posted December 29, 2012 could be a sticky piston so prehaps clean it, also the top up method you tried i found isnt the best, the best way to do it is to get a syringe and remove the plunger, remove the lever grub screw put the pipe in the lever with the plungless syringe on obviously with you fluid in, then simply pump the lever in and out, pump it a good few times, drives out air and fills your brake up! should get rid of the slack! and makes them feel brand new again! if its a 05-10 lever then aim the grub screw to the sky, think that worked best! try that before a full re bleed Quote Link to comment Share on other sites More sharing options...
dannytrialskid Posted December 29, 2012 Author Report Share Posted December 29, 2012 Just done face time with Paul turner (narrowbars) and he helped me sort it. The piston was swollen so I sanded it and stretched the spring a little. All good just got to re bleed and make sure it doesn't leak :/ touch word Quote Link to comment Share on other sites More sharing options...

liam n Posted December 30, 2012 Report Share Posted December 30, 2012 The Method on my website isn't really a fail safe way of bleeding your brakes, it's more if you're out on a ride and your brake becomes sloppy etc. you can just top them up and if you're doing it right there shouldn't be a problem, Definitely worth Completely Re-Doing the bleed when you have the time or w/e Did sounds like a swollen Piston (you can tell when you're pulling the lever in and the piston just sticks at the bottom), which does happen every so often if you've had a water bleed, I should probably do a video on this! Glad you got it all sorted out, as long as you took the O-Ring off when you did the sanding you shouldn't have a problem with leaks. Quote Link to comment Share on other sites More sharing options...
williams Posted December 30, 2012 Report Share Posted December 30, 2012 Sorry too hijack the thread, but could you get a swollen piston with a oil bleed? Quote Link to comment Share on other sites More sharing options...
Rockman Posted December 30, 2012 Report Share Posted December 30, 2012 (edited) If it's an 05 HS33 the bleed port doesn't face up. You put the lever at a downwards angle of 20 degrees. Edited December 30, 2012 by Rockman Quote Link to comment Share on other sites More sharing options...
