Coaster Posted April 5, 2015 Report Share Posted April 5, 2015 Hi, i'm from Germany and i get mad using my new Trial Tech back brake. Since the first day the lever has no bounce after release the levers after pulling the brakes. I bleeded the brake several times and the bite point is good too. There is also a squelch sound from the inside of the lever where the bolt goes into the lil plate to the piston. May there is a problem with the seal and the spring in the inside? I have the same brake in the front and that one is perfect. Thanx Quote Link to comment Share on other sites More sharing options...
monkeyseemonkeydo Posted April 7, 2015 Report Share Posted April 7, 2015 Something's definitely not right there. The squelch will be some air in the system so the question is how to bleed it so that you remove all the air. How are you bleeding it? How long have you had the brake? Possible to take out back to where you got it? Quote Link to comment Share on other sites More sharing options...
Coaster Posted April 8, 2015 Author Report Share Posted April 8, 2015 Got the brake some weeks ago. I had the problems right from the start and i bleed like in the Hope videos. I did it in the past with my sons bike and it worked fine. that brake was filled 5 times in the last week but it don't gets better. Quote Link to comment Share on other sites More sharing options...
MartMini Posted April 8, 2015 Report Share Posted April 8, 2015 try loosing the lever pivot bolt, see if it makes a difference? On magura's, if they're too tight, it causes friction on the side of the lever, which could cause this Quote Link to comment Share on other sites More sharing options...
monkeyseemonkeydo Posted April 8, 2015 Report Share Posted April 8, 2015 Yeah does look like excessive friction at the pivot... Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted April 9, 2015 Report Share Posted April 9, 2015 Yeah, tight pivot, have seen that before, usually the pin / bushing. Remove the T10 screw that clamps the blade to the pivot pin and see what happens. Quote Link to comment Share on other sites More sharing options...
Coaster Posted April 18, 2015 Author Report Share Posted April 18, 2015 No, even without the screw it does not work well. Every thing is running free. Still slow. My son is using the same brake, about 2 month without big troubles. 10 minutes ago he took his bike and noticed that he has the same problem with his back lever. I hate this Hope brakes!!! Yesterday they were fine and no one touched the bike since now. No oil at any part of the bike. Pressure is ok also. How can that be? I asked Hope, the biggest Trial shop in Germany, Tarty bikes and some guys working in bikeshops. No one can tell me whats up. Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted April 20, 2015 Report Share Posted April 20, 2015 It's very difficult to work out these sorts of problems without seeing the brake, if it was here, we would know immediately. Quote Link to comment Share on other sites More sharing options...
waybe2014 Posted April 20, 2015 Report Share Posted April 20, 2015 This should be a stupid question but what fluid did you use to bleed them (only ask as you said there was no oil leaks) Quote Link to comment Share on other sites More sharing options...
