Squeaking brakes

I've read here and elsewhere about Stromers having "inevitably" squeaking brakes.
And mine did when I bought it.
Until I used them hard enough to deglaze the pads and now it doesn't.

This is the same problem as with car brakes since they did away with asbestos and went to metallic and sintered brake pads. These are MUCH harder pads and if you use the brakes the "old fashioned" way, coasting up gently and babying the breaks as much as possible, you create a "glaze" of dirt and brake pad material that sits on the surface of the pads and rotor.
When you squeeze the brakes gently you only rub the glaze on the pads against the glaze on the rotor.
Techs are constantly deglazing brake pads now, sanding the "glaze" off the pads and rotors so that the actual tough, scratchy pad material "bites" into the rotor like it should.
Cleaning the crud off is the first step, and many do that. But if you go back to light easy braking, it just builds up again.
The answer to squeaking pads is using the brakes harder. Dont' start braking so early and using them lightly, keep speed up and off the brakes until closer to stopping point and then use them HARDER.
Not unsafely stopping late or needing to skid, just using them enough to keep cutting through the glaze and making brake pad material to rotor contact.
If that makes you nervous, at safe open place, just hit the brakes hard and slow quickly (not panic stops) a few times till the squeaking stops.
Brake pads are CHEAP and last a long time. AND we've got regen..................

USE THEM HARD and they won't squeak. ;)

I used to gently apply pressure on those two beautiful black levers and she (ST2) would moan before coming to a complete halt.
but now I ride her hard and apply good enough force to engage the caliper lips on that round rotor.
She squeaks louder and makes a lot of noise.
Am I doing it wrong?
:p

LOL, no but you might need to take the brake cleaner and/or sandpaper to the rotor and pads to get rid of the glaze. on mine I didn't, but it didn't have many miles on it either.

And I should note that as soon as I posted the message, I got a chill and thought "I sure hope my brakes don't start squeaking for SOME OTHER reason now" LOL

Sadly, the Magura pads that come stock are crap in my opinion. I have tried the Clarks metallic and organic and recieved the same results. Switching to the Jagwire Mountain Sport pads have cut the noise in half compared to the previous 3 sets.

Magura should just allow Jag to supply their pads at the OEM level at this point until they can make a decent pad. They make a really good brake though. I prefer them over everyone else except Shimano and Hope and even that is so close it gets defined by bike style which is best in my opinion.

Noise in disc brakes are common and just considered part of the cons of the system and tolerated for the pros. But on these bikes we are going faster which also translates to more time applying the brakes in terms of number of times used and duration of usage. I think it is just something we have to accept for the time because it does not seem that the tech to do away with the noise exists.

Would you like to try mine?

Well. I spoke too soon. It came back. It started squeaking again when I was polishing my bike last night. Just little micro squeaks coming from the back rotor when I move it around. I dumped a bunch of alcohol on it and it's 90% gone. The front brakes make a weird buzzing sound...

I'm quite frankly a little relieved that this type of thing is "normal" for Magura brakes, because otherwise I'm very happy with them. They stop great. I don't have a Stromer, but I do have Magura brakes. Mine are the Mt-5. What do you guys have on your Stromers?
