    Break Problems (squealing)

    Hi there,

    I'm having some problems with my car at the moment namely my breaks. When I first bought the car last month my breaks would squeal every now and then but now it's at the point were each and every time I drive the car the breaks squeal so loud that it's becoming very annoying & embarrassing.

    Does anybody have any ideas as to why my breaks might be squealing? I'm thinking first port of call would be the pad's but I'm unsure on how to check/remove them? Thanks in advance

    if its a constant squeal could be the pads are low and its the screach clips on the pads rubbing against the discs. or it could be that they havent been greased up properly.

    Got this when I changed my pads. Put copper grease on the non friction side of the pad, between the pad and the piston.
    The squeal is actually a high frequency vibration (no smart arse's)

    This is going to sound daft but, Is there a way to see if the pad's are low without taking the wheels off? lol, and also it sounds as if it's coming from both the front and back of the car. The back are break drums. What's the process for checking these?

    the back drums could be full of brake dust that would cause it

    It would be best to check the pad and shoe thickness anyway. It not a big job to take the wheels off!

    If you have alloys you might be able to see how much of the pad is left through the spokes of the wheel. However as suggested your pads might be getting low, so the wear indicator pin is squealing to let you know. Also does this squeal happen when and only when you use the brakes or all the time when driving?

    If the latter it might be that there is a stone caught between the dust shield and the disc or the dust shield is bent onto the disc causing the squealing, as this happened to mine after it had been to a garage.
