Hello,
i know this topic has been covered before and i have looked using the search box however the problem i am having i havent found..
2 weeks ago i changed my pads and disks to Pagid disks and pads and they were fine until i had done around 200 miles and they had bedded in.
Now i sounds like i have trapped brake dust as there is a squeak and sounds like something is rubbing. It can vary from turning left, right or driving straight on. Also it sometimes does it when it is at low speed only, high speed only or a mixture?
i have read some threads about wheel bearings etc but it was fine until i did the disks and pads? I jetted water in there which stopped the problems..for about 2 hours and then started again?
any suggestions how to get rid of the problem or what it could be?
thanks in advance

no, the other other side, aparently greasing the back of the pad helps reduce squeaking.
i dont really agree with grease and brakes but you could put a small dab of coppergrease on the disc and it will spread round whilst driving, this tends to stop squeaking ...make sure you test the brakes and know your new stopping distance as they wont be as good as before, takes a few miles to get back to normal.
remember you can always put more on, removing excess if more difficult!!
i should also add, do this at your own risk

Copper grease has been used for years on brakes. It doesn't go anywhere near the friction material or the disc. I don't know of one person reporting reduced braking efficiency due to copper grease. I even use it inside my drums to stop the shoe rubbing on the back plate. You have more chance of loosing brake efficiency by driving trough water.
As with anything, if you don't know what you're doing, leave well alone.
Take your pads out, and coat the metal back plate where it comes into contact with the calliper with copper grease. Some cars have shims behind the pads which can stop the squeak but I always cover them too just to be on the safe side.
You could also try filing off the leading edge of the friction material at an angle. I have found that doing this can stop the squeak, but this may be a placebo effect as I've always greased the back of the pad too.

which is why i said "aparently greasing the back of the pad helps reduce squeaking" ...seems to be more or less what you are saying ..no??
obviously its its not going to reduce breaking efficiency if its no where near the friction material.
when my brakes squeaksed the garage put a dab on each of the 4 discs ...it worked and the squeak stopped
this did reduce braking efficiency for a few miles because it was on the friction material

This must be the worse advice I've ever seen here 
& you later say a garage done this to your discs, I think maybe they didn't like you

This sounds like a cowboy garage!!! Why on earth would you put copper grease on the disc!!!!!! NOT CLEVER, only apply copper grease to the BACK of the pad not the disc!!!

you can bin the pad if it has been contacted with grease/ oil

Copper-ease (or even better, ceramic grease) does help matters for quite a while.
However, pad quality and/or hub&caliper symetry are the real culprits in my humble experience.

You say that the squeak has occurred after 200 miles of bedding the brakes in? How have you bed them in?
People forget that there is a correct procedure for bedding brakes in, the garages motto of "drive carefully on them for 200 miles" is not it.
This has been covered on the forum before, but summarised it consists of a series of hard slowdowns without actually coming to a stop after each one.
Following this procedure correctly decreases the chance of brake squeak and increases their efficiency. (However it won’t guarantee the brakes will be silent as it does also depend on the quality of pad/disk)
See Here: www.youtube.com/watch?v=4adZEf0f9wo
And Here: www.youtube.com/watch?v=9GmdwQtjaQc
Following that procedure I have never had brakes squeak.
Hope that Helps.
