Heard of this the other day. Wetting new pads and rubbing them together to accelerate bed in.
Has anyone tried this? I always just ride around with the brake on, increasing heat and pressure but always open to new ideas, especially if they work better.
Hmm the whole purpose of brake bedding is to condition the friction material.
Conditioning requires pressure and thus heat to 'modify' the friction compound and make the friction and NVH behaviour more consistent.
Rubbing wet pads together (presumably by hand) won't create enough heat and there won't be much pressure involved.
So I wouldn't be doing that 😉
That was my thinking, it doesn't logically align with what's needed to bed pads in. However, you can't argue with results (if anyone is getting results), hence the question
Never heard of that.
It generally only takes 10secs or so of braking for new pads to start biting properly, in my experience.
Solution looking for a problem?
Some muck on pads and discs can do wonders for brake operation - both 'grab' and overall power. I have been known to throw muck on brake systems while out riding.
I remember in days of old, Hope used to take jars of mud to races with them for bedding in brakes. Always assumed it was a promotional gimmick
I do this every time for new pads. Not quite sure what the logic behind it is: Cleaning up the surface? Removing anything from the manufacturing process or added after? just roughening up the surface? It's not an exercise in building heat.
When rubbing my hope pads together they start off smooth and then there's a sudden increase in friction after 20 seconds or so of rubbing together wet. I usually need a re-wet mid process. I find the pads initially work better when doing this vs not doing this.

I don't think it's bedding in per se but it seems to speed up the subsequent bedding in (and the fewer hill repeats I need to do for bedding in, the better)
I used to pour a bit of water on mine before bedding them in as that's what Dave Garland recommended and it seemed to make sense. Last few sets I've done however I've just done the few gentle stops down a small hill technique. There's very little difference but then I'm not doing them to multiple bikes several times a weekend so what do I know.
I think the theory was that it helped to lubricate things and take the high spots off/align the breaking surface to the disk
I always do this; the friction really picks up after a few seconds when rubbing the wet pads together.
Quick rinse once that’s happened and install; good bite from the first lever application. It seems to do away with the need for lots of initial heat generation.
I usually give mine a quick rub on the garage floor to rough up the surface and remove the 'glaze' before fiting, then bomb down the hill on my road a few times braking hard but not stopping. Seems to work.
I always thought the build up of heat was part of the process...will try this wet rub technique at next pad swap.
Bee doing it for a while.
As others have said seems to take the initial glaze off and makes them bike better from the start.
Never heard Peaty or Minnaar complaining about brakes lol
Same with the Marshy Shimano bleed method - that works really well.
