Ladd Posted December 12, 2007 Report Share Posted December 12, 2007 Rite im runnin a deng leaver body , maggie calipers and braided crossover also it is water bled. when i bled it a few weeks back in a bath bleed, i put the hole brake under water with a saringe of water on it pushed the water in though the saringe under water done the bolts up under water and took it out pulled the leaver and it wouldnt do anything to the calipers until i pulled the brake about 4mm feels like there is no fluid for the first 4mm you pull the brake, but when the tpa adjuster full it is fine why is this, Many many thanks mike x Quote Link to comment Share on other sites More sharing options...
Tom_ Posted December 12, 2007 Report Share Posted December 12, 2007 Because the TPA pushes the piston in, by screwing it in you are pusing a piece of metal into the back of the cylinder further thus pushing the cylinder in, when you wind the tpa all the way out there is some slack between the peice of metal that pushes the cylinder in and the lever blade, therefore you get for and aft play that doesnt effect the cylinder atall. I think, although I think you said you were running a dengura lever, dunno if its the same but thats why maggys do it Quote Link to comment Share on other sites More sharing options...
James Quigley Posted December 12, 2007 Report Share Posted December 12, 2007 When you bleed the brake (even in a bath) make sure the TPA is wound all the way out.Also pump the lever as you force the water through the syringe. This is because Air gets trapped in the lever and when you push on the syringe it just goes in one hole and out another, by pumping the lever you're forcing the air out of that 'resevoir' and all it can suck back in is water.Hope that helps Quote Link to comment Share on other sites More sharing options...
Ladd Posted December 12, 2007 Author Report Share Posted December 12, 2007 ok cheers well the tpa was wound all the way down, but i didnt try pumpin the leaver under water cheers. Quote Link to comment Share on other sites More sharing options...
James Quigley Posted December 12, 2007 Report Share Posted December 12, 2007 make sure you're pumping water through as you're pumping the lever. Quote Link to comment Share on other sites More sharing options...
N Roach Posted December 12, 2007 Report Share Posted December 12, 2007 (edited) Take lever off and Sqeeze the lever under water, your be suprised how much air is in there. then add the first hoosing and sqeeze then the first cylinder then sqeeze etc Edited December 12, 2007 by Koxx_Nath.C Quote Link to comment Share on other sites More sharing options...
Nick Garland Posted December 12, 2007 Report Share Posted December 12, 2007 This happened on my last bleed with my dengura brake, however I did not pump the lever, normaly I dont and I have the same play feeling that you mentioned. I shall try pumping the lever when I bleed it next. Quote Link to comment Share on other sites More sharing options...

If you have a syringe, why not just do it with that? Much easier and less hassle. Perfect bleed every time. Quote Link to comment Share on other sites More sharing options...

Ladd Posted December 17, 2007 Author Report Share Posted December 17, 2007 just tried bleedin it again and i have tryed all the different ways people have sugested and it just doesnt seem like enought water is going into the brake ?? Please help Quote Link to comment Share on other sites More sharing options...
Lawnmowerman Posted December 17, 2007 Report Share Posted December 17, 2007 Completely submerge it into your bath, take both bleed bolts out and pump for 5 mins with the tpa out. Then put the bleed bolts back in while still under water. Quote Link to comment Share on other sites More sharing options...
Balman Posted December 17, 2007 Report Share Posted December 17, 2007 right this is THE ultimate way of bleeding simpson showed me and it should be copy written its worked really well for me.undo the bolt in your caliper leave the bolt in the leaver in make sure tpa is all the way down take the leaver blade out and the small rubber seal thing now dunk the hole thing under water and there should be loads of bubbles comming out. Then put the small rubber seal in again and get like a 5m alan key and keep pumping the rubber seal untill no more bubble are coming from the brake caliper after a while of doing this put the bolt back in the caliper and put the leaver blade back in tighten it all back up and you should be able to take it out of the water.Some times you get a touch of over bleed were the calipers are all ready out as they would be if you pulled the leaver in to solve this undo the bolt by the caliper just a touch and it will let the smallet bit of pressure out and quickly tighten again and the brake should work absloutly spot on tis what i do with mine after simpson showed me his methord and my brake feels mint now. hope this helps if anyone more intelgant than my self could point out a reson why this would be not good for the brake or can see any fults let me know as i dont want to be giving out advice that is not correct and get the blaim but i have found this works best for me. hope this helps Jack Quote Link to comment Share on other sites More sharing options...
smoke257 Posted December 18, 2007 Report Share Posted December 18, 2007 Hey i had this, try leaving the bolt on ur caliper in, then pump water in to the lever with the syringe, this pushes the piston out to the max worked a treat for me. (make sure u do the rest of the bleed aswell.) Quote Link to comment Share on other sites More sharing options...
