brake wear

[percypineapple]

Occasional grinding noise from rear wheels when braking, on focus c max auto, with 35k on clock. do the brake pads wear faster on the rears on an automatic?
it is driven in London all the time, so stop start, and obviously pulling on rear brakes when at traffic lights etc. Just thought I'd ask before taking wheels off, might save me putting it back on and going to the motor factor, then taking it off again I somehow listed this under law the first time, thanks for letting me know.,

thanks,
Percy.

Grating on the rear could be rust on the pads due to "After rain" & they car standing a day or so, front brakes wear the most as when the foot brake is applied, the control the front brakes first then the rear, I would drive the car with your handbrake on slightly on the brake pedal to clear the rust. there could also be a Lip on the disk at the rear, you can see thuis without removing the wheel. you may also need pads at the rear.
