No Lock On My Magura

[Gavyn.]

Right i had an 05 leaver on but it leaked like nothing else so i swapped it for an 04 leaver and bled it. it was quite a good brake for a 2-3 days but now it feels awsome but there is no lock when it worked it it had a noticeable amount of sponge but now its solid but theres no grip in it at all

anyone else had this problem and know how though fix it then please help me out.

cheers Gavyn

btw i did use the search

kinda sounds like the piston is bottoming out in the lever before the brake has time to contact fully.

I reccomed a new bleed but remember to unwind the tpa all the way out.

If the lever's quite spongey there might be air in the system, caused from a bad bleed, and just making the brake not work well, and in your case, have no hold.

Check for leaks in the system, if it's all ok, give it a fresh new bleed and it all should be fine

I've never had this problem, so if bleeding it doesn't work then i'm not sure

Yep thats it (i think) the piston might be hitting the end of the cylinder before there is enough pressure forcing the pads to lock on the rim. When you pull the lever in does it lock out (Stops and doesn't move any closer) and the pads aren't holding on to the rim enough?

If it is that try;

.A new bleed

.Moving the slaves in closer

Take the wheel out of the bike and pull the lever.

If the brake lever bottoms out at a fairly reasonable point (i.e. where it would if you had brake pads in) then you'll need to do what Ali C said.

If the lever goes all the way to the bar without bottoming out, something else is wrong.

yer ali was right forgot to undo the tpa before i blead it so when i did undo it the brake just bottomed out :$
