Having a strange issue with my Magura Marta Magnesiums that I need some help with.
These are new brakes with only 5 or 6 rides on them. Initially they felt really good but after 2 or 3 rides I noticed that I had to pull the front lever a lot more to get braking power so I thought maybe it got air somehow and I proceeded to bleed the front brake.
While bleeding, I noticed that after pushing and pulling the fluid a few times it seemed like a vacuum formed and if I pulled on the plunger on the bleeder, the fluid at the EBT side wasn't going down, when I released the plunger it would get sucked back down. Didn't think much of it at the time and just finished bleeding and put everything back together.
After the bike sat over the weekend, the piston on the handle bar seems to be stuck down now. It is engaging the brakes to the point that the wheel will not roll freely but it is not locked either. on the handle bar side I can see that when I push on the lever, the piston is not coming back up(or it is coming back very very slowly). Tried to bleed the brakes again and once I push the brake lever in, the piston goes in and then stays there and I cannot push any fluid in until the piston comes back.
Is there anything I can try before calling Magura and sending these in to get fixed?
