Brakes pop ?

[sjw]

Did I hear my brake calliper pistons just go pop ?

I dont mean go bang, just a muffled pop, like you might hear if you put a cup upside down on the table.
Bike is only 8 weeks old, and has sat in the garage for 2 weeks whilst it was damp and too cold to ride.
Sunny day yesterday, got to end of the drive, braked, and I am sure I heard one of the brake calliper pistons pop into place, and again at the end of the road.
No problem with braking before or after

Did I imagine that or was it something else entirely ?

I do not think that its the brake pistons, but I have heard the noise, more a single "knock" than a pop...its seems to happen occasionally on the first firm brake from overnight rest... I think its more likely to be linked to the forks. Anyone else heard it?

mine dose this its the pads moving in the callipers front to back. clean the pads and put some copperslip on when you put them back in ...
