There are several answers which could be the cause of brake squeal but my 40 years as a motor vehicle technician lead to me to think that the answer pointing to a stuck calliper is the most likely. The reason that the squeal occurs after having been parked is that the last foot brake application will have forced the callipers hard on to the brake pads to apply the brakes and the stuck one will not release afterwards and keep the pad pressed hard on the disc. As the wheel starts to rotate when you use the car again the disc will force the pad away very gradually because of slight side movement due to slight disc run out and/or very slight wheel bearing movement. The squeal may reoccur after you have used your brakes again and are travelling slowly. As the discs and pad warm up the friction coefficients change and the squeal reduces or stops until they cool down again. This relatively light pressure which continues when squealing for longer than normal brake applications eventually causes glazing on the braking surfaces. To rectify this problem the offending calliper must be removed and cleaned or replaced and the braking surfaces deglazed. Hope this helps even if it is a bit wordy.

Brake Dust

Brake dust, have a shop put the car up, blow out the dust, and spray "Anti-chatter" Brake spray on the pads, it stops after 20 minutes after the brakes heat up.

It could be just brake dust which was the case with my car, i went to the petrol station got the air hose and blew all the excess dust from around the front wheels and it worked a treat

Quite often this is due to movement of the pads on the cylinders. Pop the pads out, put a smear of 'Copperease' on their mating surfaces and on the edges in contact with the calliper.
JUST A SMEAR don't go mad with the stuff you do not want to lubricate the pads!

Get your brakes checked. It could be the wears clip,or squeal clip telling you that they are getting past the minimum thickness required to be safe. Or it could be that you have glazed rotors...They look black and need to be resurfaced to stop the squealing. Take it to get check...Better safe than sorry

I have had that happen Kwick Fit said it was dust on the pads and they took the pads out a sprayed them with some cleaner stuff that stopped it for a while then it came back for about a week and then it has stopped and has not come back
