If by the dust cover you mean the round rubber seal that seals out dust and
moisture from the piston, you will not notice any problem immediately, but
if left off or broken, moisture and dust will get in and score and corrode
the brake caliper and piston, ruining your seal for brake fluid and leading
to an expensive repair.
Much cheaper to replace the seal now than the internal disc parts later.

plan B, added shims which worked a treat.

doing so, tore away the "dust cover" - about 30% coming away in both cases.
It had become glued to the shoes by the anti squeal gunk.
