Opinions requested please on recurring noise on my daily Mk2 Skoda Octavia
After ~30 mins of motorway speeds i get a high pitched constant squeal/screech from the offside front wheel area.
Its not brought on by braking but does disappear if i tap the brakes.
It does not change if i depress the clutch pedal.
No noise at low speed
My initial thought was wheel bearing but jacked up and checked for play by rocking front wheel - none is evident. Also this is very different from the bearing noises on youtube videos which are grumbles/growls.
So now I'm thinking brakes but this is very different from brake squeal I've had before which has been when the brake pedal is depressed and not constant when not braking.
Any opinions or experiences from the wider audience please? Thinking brakes sticking on? slide pins? Crud stuck in the pads?
Anything else I should look for please? Full time job plus two young kids means I'm very short on time to investigate
Thank you all in advance
