Just a couple of thoughts.
You should always include fusing on the DC side of the rectifier.
Also be aware of the requirement for DC rated contacts on the TDO relay. UL listed devices rated for breaking DC voltages in excess of 48V are not very common.
The TDO delay must be set long enough to bring the motor to a stop, but not long enough to overheat the motor windings. The addition of a zero-speed switch can be helpful when braking time is variable.
