Seized calliper Dave or at best pads sticking in the carrier.

Tony.

What Tony said ^^^^^^^^

Yep, seized caliper

This is why you need to resolve it urgently. Nearly new pads destroyed in 200-300 miles and starting to break up from the heat of a sticking front caliper.

Compare left and right sides together here.

And see crack in pad material and general surface break up.

I’ve just finished rebuilding my first pair of rear callipers today.

From this.

To this.

Mine turned out to be the inner drum shoe for the parking brake.

Are both pretty straight forward fixes for a machanic? ?

Yes Dave, simple job. Only possible issue is bleeding the new calliper after fitting, but that's easy to talk you through. Tools needed after removing wheel are, a 7mm alley key or socket for slider pins, 14mm spanner for flexible hose and 7,8 or 9mm spanner for bleed screw depending on size fitted in new calliper.

Yep, had the same issue and recently had to change a siezed rear caliper. Not a difficult job. If you're feeling adventurous you could rebuild the old one with a repair kit, but if you just want to swap the caliper for a new/reconditioned one it's worth shopping around as prices vary enormously. For some reason rear calipers are much dearer than front ones.

Because rears are unique to Z3. Fronts are used on various models. Supply and demand. That's why I rebuilt my rears and bought in fronts. Though next time I may rebuild the fronts too. Best try these ones I've just done tomorrow first though.
