There is a horrible sounding high pitch squealing noise coming from my front drivers side wheel I think. It is only when the car is moving and doesn’t really change under breaking or accelerating. I only really here it when I have the window down but it is deffinetly there and gets louder when I pass something on that side as the sound bounces back. What could it be and how do i fix it?????

its probably the shims on the pads will need replacing or you could just have stone between the pad and disc

the pads are probably low and thats the warning you get !

sorry should have mentioned that i had checked the pads and they have got plenty of meat in them still. If i have got a stone wedged in how do i get it out? do i need to take the calipers off? how can i be sure which wheel it is (it could be front or rear drives side)?

Clive - the inner pads have a metal bracket on them that catches on the disks when the pads get worn down. You need to check both front rear pads. It's simple, losen the wheel nuts, jack-up the car, remove the wheel, remove the 2 pins that hold the pads in place, remove the pads and check their condition.

 

The pads are pushed onto the disks via 4 pistons, if either bank of these pistons is sticking then you'll get uneven pad wear.

 

When the pads are out take a flat bar and carefully prise these pistons back into the calipers but first put a pad in the other side of the disk so that these pistons don't pop out. Do this to both banks of pistons - and make sure your brake fluid canister (engine compartment) dosn't overflow.

 

Grease everything lightly with copper grease and put it all back together.

 

Watch out as you'll have no brakes untill you've used them a couple of time.

 

...good luck, this is a simplified version of what needs doing, so, please take care.

I had this on the passanger front wheel was the wheel bearing, to rule it out jack the car up leaving the wheel on get hold of the wheel at the top and bottom and see if there is any play in the wheel as you rock it back and forth.
