Check your brake pads. If they have the same amt or less pad vs the steel backing, it's time to change them.

Then flush the brake fluid. Porsche recommends flushing the brakes every 2 yrs. If you plan to track your box, you'll be required to flush every 6 mo.

The emergency brakes are operated by a separate pair of shoes (not pads) on the rear disks. They are not related to the disk operation. You may be able to manually open the shoes up so they have more bite, but that's only if there's enough material left on them.
