    Suggestions for silencing Magura brakes?

    I have the MTS model brakes. They came stock on my carbon stumpjumper. If it weren't for the noise, I'd love them. I ran several sets of Hope's and a set of Formulas in the past and never had an issue. Do the stock pads suck? Running the Storm SL rotors. Higher speed braking will wake the dead. Anything I can do?

    Not sure what pads your SJ runs, endurance pads are a litlle bit noisy, performance tend to be more silent. Another option before changing pads is to swap the position of your pads, just take of the retainer bolt and change sides of the pads, it has helped me. Hope it helps.

    Something seems weird. Maybe contamination?

    My MTS8's are dead silent.

    On a similar note I paired up new hayes stroker trail brakes with maggy storm 160 SL rotors and did wake the dead time & time again only to eventually replace them with larger 185 avid clean sweeps and not another squeal was heard from break-in to numerous rides later. Harmonics play a key role I suspect.

    It's the "hi friction" pads. I didn't have any issues today, but this particular trail is tight and twisty and don't have to brake at higher speeds. I'm going to pull the pads out later today and look at them. I'll try the repositioning advice.

    not in my case, i gave organics a shot with the same result and quickly burned a pad groove in them in 4 hrs...no thanks.

    I have no problems whatsoever with the back brake w/180 and discobrake semi metalics or koolstop organics. The front though with a 200 rotor is kind of a pain. The magura pads i did not like as they got grabby and started to pulsate quickly. So my routine is to sanitize the rotor every ride with cleanstreak. Every couple rides i pull the pads and sand lightly with 400 grit wet/dry paper and wipe with alcohol or clean streak and pay attention to caliper alignment. Not a perfect solution but it is what it is.

    Hello Old School.

    So you stated the brakes came stock on your Stumpy so I assume the pad compound may be 7.3 which is the hardest compound and longest wearing pads we make. This may be the source of your noises.
    The reason I say this is that the 7.3 pad will take the longest time to wear into perfect alighnment with the rotors. This interface is crucial not only for good friction but for also preventing vibrations which is the cause of the noise.

    So, Either wear the hell out of the pads for a good few DH -like runs untill you are sure the pad interface is good or change out to a softer pad like the 7.1.

    Another option is to find a shop or someone with a Park Tool DT-4 post mount disc tab facing tool to perfectly hand machine the mounting tabs on the frame and this will most certainly fix this and any future noise issue for your frame. (like when you replace worn out pads and all the sudden .... noise again!)

    Let me know if we can help further or if you have any questions.

    Magura MTS noise & slight vibration

    Just purchased a 2014 Spec Stumpy Carbon Comp and have exactly the same problem! Any latest ideas/updates??

    I have used Magura brakes for some time now, and had Marta, MT8, and now MT6 Maguras. I would also suggest that excessive heat can also cause a brake to howl. Not sure if you are a big guy or not, but when I was heavier and in extreme downhill runs, my brakes made all kinds of noise. Three things helped eliminate this in my experience. 1. I upgraded to larger Storm SL rotors. I put on a 203 front, 180 rear. 2. I lost 55 pounds of weight, and now am just over 200 lbs and 6'3. 3. I learned how to brake better, and sometimes not much at all.

    Riding my brakes caused noise, heat, and poor bike handling. By bleeding off speed, then staying off them, then over and again, it gives the brakes time to cool between application, and this too helps reduce noise. On my new Epic, I am back to a more normal rotor size, but again, I am lighter, my bike is stupid light, and I'd like to think I am more experienced. I am very happy with Magura as I like the feel. They are not the most powerful brake, but the modulation is excellent. Hope this helps...

    i'm using mt8 nexts now and they were perfect with the storm rotors, for one ride, so i reverted to wiping the rotors quickly with alcohol for pre ride routine. That helped but still 3/4 of the way in i got squeaks, spoke to the best shop in the area who had good luck with shimano icetech rotors so i switched and better still but after a few rides the dreaded squeak from the back. So now i just pull the rear pads every couple rides and sand lightly with 400 grit to remove the black stuff/glaze. Takes 2 minutes. I'm using discobrake pads which are fine and 1/4 the cost

    Try reversing the rotor. My MT2's on my Cannondale F29 howled and vibrated ridiculously. I flipped the rotor, and it stopped immediately. Power was down a short while until the pads/rotor burned in, but that cured the noise for me.

    This is very important. I run Magura's on two of my bikes, my downhill rig and my all mountain bike. I am 235 pounds. On my downhill bike I was running the MT2's with 203/180 rotors. Even with this setup, I overheated the MT2's on long runs, causing them to howl after overheated. I switched out the front to an MT5 and put a 203 rotor on the rear, no more howling and more importantly, can now comfortably one finger brake with no arm pump.

    On my all mountain bike I have been running Marta's for several years with 180/160 rotors. I was having some howling issues and also arm pump with one finger braking. I ended up putting in new pads and going up to 203/180 rotors. This fixed the noise issue and make one finger braking more comfortable.

    In short, if you are on the larger size, consider larger rotors to offset your weight.
