Dan6061 Posted February 15, 2006 Report Share Posted February 15, 2006 (edited) As many of you may already know, I got my bike back today. I put my new wheel on, and my back brake doesn't feel as nice. It locks and everything, but the lever comes too far for my liking. And the tpa is all the way, and the cylinders are a s close to the rim as possible. I think it need a bleed too. Also, the pads (Plaz) are hardly worn, so I don't want to buy new pads. Got no money I've seen people attach other backings to their current pads, but I think that'll be too much? Could try it though... Any more ideas?

Walleee Posted February 15, 2006 Report Share Posted February 15, 2006 If the pads hit the rim and then the lever comes in significantly after that a bleed would probobly work well, also, if you pull the lever and there is no movement at the pads, that would indicate a bit of air in the system too. With my TPA, I can adjust it but there is no noticable pad movement at the cylinders, I don't know if that should be the case or not.....

Dan6061 Posted February 15, 2006 Author Report Share Posted February 15, 2006 Well the brake feels rather spungey, but had a fresh water bleed not long before it got stolen. I'll bleed it tomorrow, but I'm still thinking the lever will come close to the bars... Quote Link to comment Share on other sites More sharing options...
Walleee Posted February 15, 2006 Report Share Posted February 15, 2006 make sure to bleed with the TPA fully unscrewed, and not to play with the lever while the pads havn't anything to press against, I believe that can screw things up somewhat.If you've bled and positioned the pads close to the rim, once the pad's hit the rim, the lever shouldn't come much closer, even if it does, you wont gain much power at the brake, chances are your stays will just flex more. Like I said, if you pull the lever and there is no response at the cylinder's there's air in the system somehow. If you pull to the point where the pads are touching the rim and the lever come's in more, again it's either flex, or air in the system......

Onza Kieron Posted February 16, 2006 Report Share Posted February 16, 2006 Rebleed the brake and if it's no better then screw some backings onto you existing pads then move the pistons fully away from the rim and it should fit, what frame and rim are you runnng.

durkie Posted February 16, 2006 Report Share Posted February 16, 2006 dude, it sounds like everything that can be f**ked up about a magura has happened to your brake. why do you think it's the pads? unless you're running some narrow-ass rim on a frame not meant for it, then tpa all the way in and cylinders as close as possible to the rim doesn't happen. just start all over.

Dan6061 Posted February 16, 2006 Author Report Share Posted February 16, 2006 Zona Zip with a Ronnie. I don't think the brake's fooked at all I'll bleed it tomorrow. As I can't be bothered now plus my mate has my syringe I didn't say I thought it was the pads at all... I said It can't be them, because they're hardly worn.

ding_dong Posted February 16, 2006 Report Share Posted February 16, 2006 could try an "over bleed", i read this once, that when you are bleeding the brake get a friend to pull on the pads so that the pistons are already a bit further out than they usually would sit, then you wouldn't need to pull the lever to move the pads as much??don't know if it will work, just an idea that i have heared before.

It really sounds like you just need a bleed. Quote Link to comment Share on other sites More sharing options...

Walleee Posted February 16, 2006 Report Share Posted February 16, 2006 cylinders are as close asposible not pads!! If he has pads in the cylinders, and his pads are not significantly worn, the pads will be closer to the rim than the cylinder as they protrude more. He has pads in the cylinder's and he has said they are not very worn......An 'over bleed' wont be of use to him. Quote Link to comment Share on other sites More sharing options...
nb88 Posted February 16, 2006 Report Share Posted February 16, 2006 How far away from the rim are the pads? Got any pics? Simple really, if theres not much gap between the rim and pads, and its still not biting right, you need a bleed.Easy way to tell if youve got air in there - loosen off TPA - pull lever lightly - do the pads move as soon as you pull the lever? If not - air. Quote Link to comment Share on other sites More sharing options...
JT! Posted February 17, 2006 Report Share Posted February 17, 2006 (edited) make sure to bleed with the TPA fully unscrewedMost important thing right there ^.Your problem dosn't really make any sence. From what i hear your pads can't be moving at all. If your pads are dead close to the rim, there should be no problem, there could be a serious amount of air in the system, or maby it's leaking slowly.The only thing you can do is bleed it (like said above) and if that dosn't work somethings really fooked.
