Squeaky brakes - lip

[Ste]

Started getting a pretty minging brake squealing noise during the last few metres of stopping the other week. The pads still had a bit on them but were probably starting to go, so I changed them over the weekend and greased them nicely and the noise is still there. Obviously the pads need to bed in and sit flush with the disk but I'd have thought that should be done by now (driven about 100 miles since changing them).

One thing i've noticed is a pretty rough/jagged lip running right the way round the edge of the disk, presumerably where the pad doesn't sit flush to the edge so wears away slightly inside the disk. The disks are otherwise fine and shouldn't need changing for a while. Is it likely the lip is causing me the problems, and if so is it worth taking a file and sander to the disk and filing the lip off so it's all flat and smooth again?

You can grind the lip off with an angle grinder,try filing them by all means but you will be there all day,using a grinder you can do them on the car.

I've done that loads of times , easy to do on the driven wheels as you can jack up one side put it in gear and grind away as the disc is turning !

once the disc is still in limit no harm done !

wouldt it just be easier to get a new set of discs? if the lip is severe enough to be causing a problem then it may be safer to buy a new set. looking about about they can be had from the likes of buypartsbuy for as little as £15 each (dont know make and assuming 04 3.0i) or motorsportworld do black diamond for £100

your brakes are kind of important

it may just be due to the salt on the roads.

mine has occasionally been squealing at low speeds with light pressure on the brake pedal over winter, but i changed the pads myself and the discs are fine.
