As soon as you use the brakes they will be 'worn' to an extent and their design puts the pads in close proximity to the disc.

Suggest you overhall the brakes, following a guide on here, which will clean out crud and allow the pads to move freely.  If you put a slight chamfer on the edge of the pads closest to the ridge that may reduce the squeek somewhat.

The MOT tester said that about SWMBO's Astra's brake discs about 3 years back. 'Worn to minimum' was his remark ........ the car has since passed at the same test station and at A N OTher with the same discs.  :-/

Measure them. There's 150 000 miles on my car and I don't believe the rear discs (or fronts) have ever been replaced. Rear discs don't tend to wear out as most of the braking is obviously done at the front.

Dont neccessarily agree.  Yes, the fronts do carry more effect due to weight transfer etc however the rears also have a part to play.  They contribute quite a substantial proportion to the overall braking effect of a vehicle - you see a substantial difference when a rear setup is working correctly.

Likewise, the pads can and do catch a lot of crud in their mountings and do stick.  This does result in drag and wear on the brake face as we all know.  Its whether you have the technical ability or knowledge to ascertain how much wear is excessive thats in question.  

Ultimately, its upto the individual if they wish to heed advice of others or not...

I'll have to agree with you again!  ;D

Just commenting that it's easy for the tester to say 'discs are worn beyond limits' without measuring them.  :y

Don't mess around - fit new discs and pads to the rears.
Best pads to use are genuine Vx or EBC.
No problems after 000's of miles either.

How much are new rear discs
