Disk still rubbing.

Thanks .

Is a piece of nickel titanium a spring?

This is quite an interesting exert from the shimano caliper manual..

"

1. Place pad return spring between new pads. Pad return spring is placed between pads. "

It is interesting because it doesn't return anything.

It returns the pads to their resting position after the brake has been released.

No it doesn't

troll.....

Yes it does, that's its job and thats why Shimano who designed it call it a "pad return spring"..

It's not in anyway shape or form an anti rattle shim before anyone tries to spout that bs either..

All that little bit of largely irrelevant bit of metal does is spread the pads apart.

It has no measurable effect on braking nor does it assist in piston return

 

[keithmac]

In order to spread the pads apart it has to push the pistons back to an extent.....

Nope doesn't have to

Or, if you prefer a version for the new digital era ...

How do you work that out then?.

It's the part in the middle of this picture, and I base this on three years of watching my front wheel spin pushing it on the back wheel from the store room to the front doors at work.

I can post a video of it tomorrow if its helpful ;-)?

a video would be VERY helpful Thank you!

Easy. In hydro disc systems the piston seals act to return the piston once the lever is returned (ie you stop braking)
