sounds like the sliders on the brake callipers are becoming siezed.

is that a big job and do you know how much please , my wife said maybe one of the callippres maybe siezing up every now and again could that be it

Not a big job really. Remove one front wheel at a time, look behind the calliper you will see two bolts which bolt the calliper to the strut. From memory they are allen key fittings. Undo the bolts, remove and enure they are clean and allow the calliper to slide on them. If you do a search I'm sure you will find a post with a little more detail.
