Magura front brake shudder

I'm noticing an odd shudder and a clatter-like sound from the front Magura brake on both my UC Pro and my Hydra when braking semi hard. It's VERY noticeable when braking hard.
Anyone else have this happening with their WW bikes equipped with Magura brakes?

Yes, mine do it too. I've read it doesn't happen with the single piece pads. The downside with those is you have to remove the caliper to change them.

On a related note, I've eliminated squealing under light pressure with organic pads from Jagwire. They definitely have a softer feel but can still lock up the wheels under any condition. I would avoid them for big mountain descents, though.

@Decon Blues, Two ideas. Check for rotor true and clean the pads. It helps to put down a white piece of paper to check for true. Spin the wheel with a rubber band slightly causing lever pressure and listen and look between the pads for side to side movement. Third idea, make sure all is tight. Acetone and Isopropyl will clean varnish residue that has cooked onto the pads. I hope this helps.

TDA78 & PedalUma, thanks for the replies.
On my Hydra there is a bit of rotor rub, but it's very slight. With my UC Pro there is zero rotor rub. Both front brakes work fine under light pressure, but under higher pressure both brakes vibrate like the calipers are loose, but they're not.
It almost feels like the pads are sticking to the rotor, then releasing enough for the rotor to turn a bit, then sticks again.
It feels like I have ABS brakes.....heavy pulsing under hard braking.

I got that on my maguras when I went to metallic pads and they got wet. then it never stopped. I had to go back to regular pads. when Changed to Shimano calipers the meal pads were fine on those rotors.

The Magura-branded single-piece pads for MT5/7 calipers are the 9-series; 9.P black or 9.C blue are available (no 9.S green version or 9.R gold)

Northwest Bikes carries SwissStop and Kool-stop pads for Magura brakes and I'm sure if you flip through the pages without the search you can find the single-piece Jagwire ones as well

Here is the chart for how the pad compounds compare, and a link to compound description (gold - race, grey performance, blue comfort, green s-pedelec)

Had pretty bad chatter on my Hydra with generic brakes where you can see the bottom of the shock vibrate when braking. Resolved after changing pads

Just one splashed drop of oil from a puddle or a smudge of sap will do this. It is easier to swap pads than to clean them with acetone. This effect is similar to rosin on a violin bow. It makes for a stick/slip vibration. Rosin is just refined pine sap. But it is still a half year until April First.

I'll try these pads next to address shuddering under heavy braking and squealing under light braking. Might even be able to change them without removing the caliper.

Even the Magura Sport pads squeal under light braking as they are still semi-metallic. And yes, they are degreased and bedded in.

I suggest staying with magura branded pads and rotors.
I got no problem with them.
My Bulls is all genuine Magura everything royal blood in the system
Da Ridiculous Bike is Tekro with MDRP.

I also experienced this with my first two rides on my Hydra this week. Would love to hear about success stories resolving this issue.
