How to silence disc brakes?
I got new brakes (Shimano Deore) for the new to me mountain bike near the end of last season. I rode it a few times before winter and everything was fine. Took it out this Spring and whenever I apply a full stop the front brake squeak really loud but stop fine.
Do you have any advice on how to silence it? Replace pads? Resurface rotors? Take it to the shop? Thanks in advance.

Threaten to replace them with rim brakes...

I know next to nothing about bike disc brakes, but is there something like "removing the glazing" from the disc for stuff (e.g. oxidation) that might accumulate over time if the bike just sits there with the brakes unused?

Try to clean the rotors with some rubbing alcohol and possibly sand the pads a bit.
Also, do a lot of fast and hard stops to embed the brake pad in more. |

As above, clean pads and rotors with isopropanol.

The SLX brakes on my Niner MCR were super loud, pulled the original sintered metallic pads and replaced with TruckerCo semi-metallic pads and they have been problem free since.

As othwrs have said
You have something on them, clean with dawn and recenter if needed The sponges with the green scrubee work really well |

Verify wheel is centered in drop outs.
Clean and/or replace pads. Clean rotor and check trueness. If necessary, reset the brake pad pistons per instructions (look them up). Low end hydraulics tend to be a p.i.t.a., especially if you remove a wheel on a regular basis. Are you getting a light squeak or does it sound like a train wreck? If it's the train wreck, you'll know what I'm talking about, in which case, replace the pads. |

If Shimano, clean with isopropanol.
If Avid/SRAM, replace with Shimano. |

Two bikes with XTR race and one with SRAM Guide, I would like to know why you think they should be replaced with Shimano? Modulation and stopping power equal to if not better with the Guide and set-up the same or easier than the XTR's.

This is funny but true. I have XTR discs on a bike and they could stop a truck. Quietly. A quality product.

Isopropyl is the trick for me.
I'm using TRP spyre and if they get loud, alky wipe and done. |

Thanks for the help!
I tried cleaning with alcohol and it stills makes quite a bit of noise. I did try sanding the pads and rotors a bit and bit not much improvement. I might just to try some new pads and see if it helps.

I hate to be the bearer of bad news, there is one-way but it is expensive. I tried everything to silence my disk brakes too. My buddy that works at the Colorado Cyclist went through the same thing, and he shared the secret with me. BUY XTR! Believe me because I didn't believe my buddy, I told him he was crazy. I tried everything, I was obsessed with proving him wrong. Turns out every other disk brake makes horrible noise nothing you can do. Is it a conspiracy to sell XTR (maybe because it's the only thing that will work)? Simple, XTR's are the best Disk Brakes on the market, yesterday and today and probably tomorrow too. Sorry if this has already been discussed I read the first post and went to answer right away, because I have been there, drove me completely batty. Satellite |
