Did you just ShartQ?

Sometimes you just gotta ride it

did you bed in the pads? ie did you ride around in a circle, slowly holding the brakes tighter and tighter?

also if hydro, did you spill fluid on your rotors?

I rode around the block a bunch doing sprints to nearly full stops for like 20 minutes, does that do it? They were silent then. Didn’t squeal until they got snow in em.

They are hydro, and even though I was super careful I may have gotten some on somewhere it shouldn’t be. It was my first bleed, after all.

I bought some disc brake cleaner for the rotors and some fine sand paper for the pads, worst case.

So fucking loud, though.

winter riding (through minneapolis) was really good at making my disc brakes howl, in my case I’m guessing it’s because all of that snow melt was a really efficient way to transfer oil/grease/crap from the road surface to my brake rotors.

That’s probably it.

Brake contamination will burn off, but they have to get really hot to do so. You can either just deal with the squeal or ride down the biggest hill you can find dragging them and wait for it to go away.

This is exactly what it is, road snow sludge is an incredibly effective pad fouling mechanism

Every time I have had extremely noisy brake pads, it has been contamination.

I am sort of a believer in hitting them with a blowtorch/bunsen burner to ā€œburn offā€ the contamination but usually it’s smarter to just get some new pads.

Eh, i’ve only had pads once that wouldn’t just burn off the contamination on their own - and those pads got contaminated with mag chloride from driving down a snowy road. If it’s simply from riding in the snow, it should take care of itself with a torche or just heating up on its own (but most casual riding doesn’t get brakes hot enough so this is harder to do).

Mtbing is a bit easier to heat up the brake and get rid of the squeal.

Metallic pads and a brushed stainless rotor has been the best for me for minimal squealing. Anything that does make it onto the rotor can get burned off after a hard brake or two.

i just rub the pads on a little sandpaper and blow torch em and that usually cleans them right up
but sometimes i’ll get some contamination just from sitting int he basement, that really annoys me

Metallic pads and especially the beefy Shimano rotors will squeal when it is wet. No way around it.

Anyone have a Tongshen e-bike motor that could measure some dimensions for me?

Is this stuff any good?

It says right on the bottle ā€œHASSLE TUBELESS SEALANTā€ which is not promising at all

But if it is actually pink I’d use it

respect to Muc Off for doing minimal packaging. how does the syringe connect to that package?

It is actually pink.
True minimal packaging would be like a cardboard milk carton with a resealable plastic cap.

I hate the way their sealant smells

Wait a minute…

Well is it? Have you used it? I’ve only used Stan’s an Orange.
