Anyone know how to get the calliper to retract on the pads on a Ford Streetka so I can get the fecking things back around the disc ?

Google has been useless in this instance.

There must be a trick, cause it doesn't seem BFI is doing much good.

 

I meant retract the piston, of course?

 

Don't worry. Sorted it using a big old clamp from the garage

 

That's exactly what I do - no effort & less chance of binding the piston.
