Help? Louise - Going to mush within 3 weeks of bleeding

562 Views 6 Replies 3 Participants Last post by  CharacterZero
I want to preface this with the statement that I am and have been stupid happy with these brakes, as they have held up for 3 years with only two bleeds and a couple sets of pads - low maintenance, powerful, etc...

So I bled my front brake a few weeks ago and got it dialled. This was (coincidentally, hopefully) my first time bleeding them. I followed the instructions on the site and got them all dialled - took no time at all and the front brake felt great after the bleed. I noticed within 2 weeks that there was a loss of power and the lever actuation point was moving closer to my grip, then yesterday it is all the way in before it grabs.

I have noticed a slight "tic" sound about halfway through the lever pull - maybe the rubber grommet is out of the fluid and pulling all the way in? I have notice NO leaking/drips upon inspection - but it seems like I might be losing fluid. The pads are about half way worn.

Has anyone encountered a similar problem with these or other brakes? Thanks in advance - I need to open it up tonight to get it dialled for tomorrows ride.

Similar situation happened to me. I kept bleeding bleeding, lever kept going soft every time. I called Magura and they said bad master cylinder. They shipped me a new one free of charge in a matter of a couple days. Great service.

Thanks for the response, ya bigdrunk! Er, Yaaay, bigdrunk!

Magura has a new MC on the way to me now.
I have had issues with my rear brake being really soft. I thought it was just the brakes but maybe I need a new MC too.

These are the Louise not the BAT right? I guess it shouldn't really matter since that adjustment should not change much. Maybe I will call Magura.

Does bleeding it help at all?

Does pumping the lever with it inverted help at all?
When I have the bike up on the rear wheel it feels better than on the ground normal. I had the one bled about 3 months ago but it felt the same before and after. I think I am going to order the bleed kit and try it myself.

Was it an easy one for you? I have not done these brakes myself yet so I cannot say if it was bled propertly or not.
