dannytrialskid Posted October 10, 2010 Report Share Posted October 10, 2010 Hi, My magura hs33 has not been working that well lately. I bleed it through several times and the pressure is very hard on the syringe when pushing the water through. When I tighten everything back up and pull in the lever, the lever goes straight to the handle bar. I tried a bath bleed 10 minutes ago, following Revolvers tutorial, and no air came out at all. Tried bleeding it the syringe way again and nothing. When I pull in the lever one comes out further than the other. It is the cylinder with the bleed bolt (m6/m6 i believe?) - and it does not come out as far as the other side. It affects the performance of the brake massively! - Please help if you can? - What could be wrong. It never used to do it. It's ever since I got my limey 320 and the brake had been sitting there. Thanks, Danny. Quote Link to comment Share on other sites More sharing options...

Get some kind of oil i used cooking oil, pump the lever loads then spray the pistons and then bleed it with water again will sort it hopefully as it sounds like sticky pistons Quote Link to comment Share on other sites More sharing options...

dannytrialskid Posted October 10, 2010 Author Report Share Posted October 10, 2010 (edited) yeah and wd40 or gt85 Ok thanks man, I'll try it tomorrow. What does the cooking oil actually do to it then, because when you re-bleed with water it's just pushing out the cooking oil again?!?

Phatmike Posted October 10, 2010 Report Share Posted October 10, 2010 At least get de-ionised water if you can. Tap water will work, but it does corrode the maguras long term. As Ryan said, it does sound like sticky pistons, clean the pistons with a toothbrush and then use a lube like finishline wet chain oil (or cooking oil if you're in a rush) on the cylinders and lever pistons. (With a water bleed! Don't mix oil and water for the brake fluid) Quote Link to comment Share on other sites More sharing options...
Matt Vandart Posted October 11, 2010 Report Share Posted October 11, 2010 (edited) So bleed it with cooking oil, spray the piston (with what) then bleed with water again yeah? No Bleed it with water. Spray piston with cooking oil. is what Ryan is saying. Personally I used to use a bit of maggy oil on the piston. Best bet is to follow these instructions: Remove grip from bar. Remove lever from bar Undo clamp bolts and remove. Throw Maggy in the bin Fit Vee brakes Proceed to win.
