I'm changing all 4 of the brake disc's for upgraded grooved and yellow stuff pads this month.

I've just had a look at the current setup and found that the rear callipers have cross head securing/sliding pins which have corroded.

I'm not sure how to remove these as they have a cross head (screw style) on the outer side of the calliper.

My question is how do I get these pins out.
Do they screw out or just push?
Where the pins are corroded and stuck in position I don't want to damage the calliper whilst I remove them.

Many thanks.
