    Magura Marta's

    My 15 year old son bought himself a new Specialized Epic Carbon and the guy at the bike shop didn't install the Magura brakes properly. They were out of alignment and since my son instantly took the bike to school to ride in a remote town with no bike shop, he attempted to align the brakes himself and lost the shims through the deck. Then he messed with the lines and got air in the brakes when trying to adjust pad contact.
    Yesterday, we went back to the bike shop where we bought the bike and the guy bleeded the lines. He did it in pieces from the top and from what I could make out, knowing NOTHING about brakes, he did not remove the pads and oil got all over them. Now the front brake has little stropping power and it also makes a very loud sound. Can the brakes be saved?

    my guess would be the pads are shot, the disc may be able to be saved with some brake cleaner etc, but may aswell get them fixed properly before you replace the pads in case it happens again.

    pads never recover from getting fluid on them

    A new set of pads and the Mini-Service kit with all the hardware to do a proper bleed would be a good investment. And some Brake Kleen or alcohol to clean the mineral oil off the rotors. The bleed is simple enough to do following the instructions. The brakes should survive with some TLC.

    The performance pads work better and are quieter than the endurance pads that usually ship with the brakes, but they do wear quicker.

    You can do all this yourself and with some care and knowledge, a far better job that the, ahemm, experts. The latest Magura bleeding instructions are on my Magura Cult site and between us people here and the resource of Magura USA who are just a phonecall or an e-mail away you're totally covered.

    MaguraUSA will ship you a pack of shims and a bleedkit and you're good to go.

    I would advise you to become your own brake expert as you have no idea who the bluffers are who are just wanting to take your money.

    You will need Isopropyl Alcohol to clean off the rotors. The pads 'can' be cleaned (or should I say 'decontaminated') but the bike shop should give you new ones. That jerk knows zeeero about hydraulic brakes.

    Magura brakes are pretty fault tolerant... so I would say that just a good bleed job and a new set of pads will bring the brakes back to their rated level of performance... just remember to bleed them correctly.

    Magura brakes are a little picky when it comes to bleeding, but as long as you follow the instructions, its not a big deal, and you will have the satisfaction that your brakes will be performing just the way you want it to.
