Brake disk/pads change on my Astra, metal on metal noise??
 

Straight swap with standard for standard disks n pads...
15mins down the road a metal on metal noise ocures coming from the right wheel...
im abit confused by this as nothing was wrong or out of place...
they are loaded up with copper grease so its not a squeak...its like a grinding sound,light was fading before i could finish looking over but any ideas???
sorry if abit odd problem but its really got me stumped

Could be a seized caliper or one of the brake pads isnt in quite right, maby they just need bedding in but ive never had that problem noise wise

check The back plate not catching the disc?

Spot on mate thanks for that :)
