The honking goose

[Demannu]

Or to be more precise, my front brake.
I've got a shimano 810 on a 200mm disc, squared the pads up, cleaned the disc up, but after 4 or 5 good stops, we have the honking goose back again. Pads are low, but it's done this for years.
Any ideas how to cure this (cheaply)

Cleaned up with?

If it's Shimano there's every chance you have a faulty caliper. They're notorious for the seal between the two caliper halves not being up to the job of sealing

Some solvent I have lying around.
Cleans everything!
All pistons move freely, just very noisy. I note that in one of the reviews for it, someone does mention it's a loud brake.
I should make it clear it's the BR-M810 model, didn't realise they did more than 1 810!

I have a very old Hayes hfx9 on the back, don't think I've ever bled it, squeeze, stop!

lol just because it cleans everything doesn't mean it's the right one for these.

Me personally i use nail polish remover. I'd start with some sandpaper on the pads, then NP remover on the rotor.

Brake cleaner always honks for me...

As said above though, some Shimano are just a case of 'yeah they do that.'

I have Hope brakes.
They always squeal like a stuck pig - when hot, or wet, or covered in shit

I've ordered some new pads, so will 'acquire' some acetone when the wife isn't looking and see if it makes a difference.
I've got a 160 rotor lurking around, if i can find the caliper bracket as well I'll see if a different disc makes the same noise.

Put the new pads in this am, braking power is right back up there, and it only honks as you come to a stop, so last few metres are back brake only.
I noticed that my oe spare Shimano disc has 'fibre pads only' stamped on it. I wonder if there could be a materials mismatch?
As most of my rides are tarmac and dry tracks, I don't need sintered pads, just they are easier and cheaper to get hold of!

[weeksy]

Fibre you'll usually find being called Resin. Most OE pads are that.
You can gets lots of different types now like Kevlar, carbon matrix and of course Sintered.
