I worked for many years in the domestic appliance repair trade. To
discharge motor caps I just used a neon mains voltage tester, the type
with a croc clip to complete the circuit. thatgets the voltage down to
just a few volts almost instantly, whence you can safely short the cap
if necessary with a screwy or spanner whatever. Shorting out a fully
charged 8 or 10 muff cap with a screwdriver doesn`t do the cap,
screwdriver or customer any good In the absense of a neon device you
could use a light bulb or a resistor of a suitable value.

btw, I`ve never seen a tumble dryer in the UK with a brush type motor,
always induction motors with either capacitor or relay start.
