Why We Like The Deore BR-M6120 Disc Brake

Making its way onto the new Shimano Deore 12-speed group is the updated Deore BR-M6120 Disc Brake caliper. At the heart of the new M6120 is the high powered four-piston system that offers high stopping power and quick retraction after letting off the levers for excellent modulation and a small and large piston engagement sequence. Smaller pistons engage with the incoming rotor, followed up with larger pistons to handle the larger stopping forces. This reduces rotor wobbling under load and also reduces noise and chatter to help you enjoy the ride instead of fretting over concerning bike noise.

The M6120 keeps your lines and your garage cleaner as well with One Way Bleeding tech that, you got it, has one way bleeding to prevent air bubbles from being trapped in your lines, which improves braking feel and safety. Add a funnel tool for easy cleanup too. You’ll also be pleased to see that Shimano’s high-performance ICE Tech is onboard to keep temps under control during extended periods of braking.

Should've listened to the reviews

Got this brake about a week and a half after i ordered it. Once i installed the brake i couldnt close it? so i brought the brake to a mountain bike shop for them to check it out just to realize it had two chipped pistons. a BRAND NEW BRAKE is already broken? how does this happen? Im going to contact support and try to get a refund since it didnt work out the box ill edit the review once i start the process. Just stay away from this site from a whole.

Arrived leaking oil, contaminated pads

I returned this product before using it

I ordered both front and rear brakes. Both arrived leaking with contaminated pads. The box for the front brake had an obvious spill. The rear brake looked fine at a glance but after removing the pads I could see oil on the back of the pads.

Leaky piston seals

I've put it through the wringer
5' 11"

The piston seals began leaking within a couple of rides contaminating the pads and rotor. After the brakes started squilling loudly i pulled the pads and sure enough, an oil ring the size of each piston was visable around the back side of each pad. Shimano has an issue with piston seals so i switched brands
