Do sintered Pads go "Off" ?
 

My front discs are rusty as a rusty thing.
A quick ride soon cleans them off, but they rust again within hours.
If I leave the bike for a few days after riding in the rain, the pads stick to the disc and need a good shove to break them off.

Now I'm under the belief that sintered pads transfer some of the material to the disc to create the friction required (I may be wrong :confused:).

So is it this material that is rusting?
and also, because of the nature of sintering, the pads must be porous, so are my pads thoroughly soaked in water/salt creating the pads to corrode from the inside?

I have some new pads on order, but was just curious.

By the way, GSXR 750 K7 radial callipers on SV1000 disc.

Sintered pads are made from a powder that is heated to fuse the particles together, some constituents of the pad are ferrous metals, it's these that corrode and cause the pad to stick to the disc, which is completely normal and not a sign that they are 'going off'.

But surely if they are corroding, then they are deteriorating. (ie going off).

Ferrous metals rust. With brake pads and discs a new surface is being revealed every time you use the brakes. This is why most cars/bikes will get a surface rust on them when there is lots of moisture in the air.

1 1/2 hours after getting home :-o
You can see on the tyre where the rust has been scraped off previously.

Are your discs near the near minimum thickness mark?

Re: Do sintered Pads go "Off" ?
 

I don't know about that.
I'll mic them up tomorrow.

That shouldn't make a difference though should it?

EBC discs by any chance?


If they are, mine do the same. Rust after an hour of standing still.
