New to MTB Forum but wanted to put out some info as I landed here in search of answers to a problem with Magura MDR-P brake noise. Running MT7's with Magura spacers and 220mm MDR-P rotors front and back on a turbo levo expert carbon 29er. Brakes are absolutely fantastic except that there's a ping, ping, ping sound during heavy braking on steep descents. You can feel it through the handlebars (it's not subtle). Won't do it on a work stand or on the flat, just on steep descents with heavy braking. Adjustment and bedding helped but didn't eliminate. Sent a video to Magura tech and was told it's an alignment issue and that the fix is refacing the caliper mounts as most mfg's don't do a perfect job of getting them perfectly flat/aligned with axle. MaguraTech mentioned that when alignment isn't true with the axle, the pads can dip into the large holes on the rotor causing the dreaded ping, ping, ping. Makes sense by what I observe. Getting them re-faced or buying a tool to do it myself as I love these brakes but hate the sound, I'll post how it goes.
