Hit pothole- now abs /hand brake fault?

[seb.g]

My mum hit a pothole the other day, she broke the 2 nearside alloy wheels and as if that wasn't bad enough, there is now a fault with the car.

We are getting a fault code 00290 - rear left wheel speed sensor faulty signal intermit
and
01316 ABS control unit - check fault codes- intermittent

Changed the speed sensor but to no avail. When you start the car and drive slow he faults can be cleared. As soon as you hit 30mph the fault lights flash up and it says parking brake fault on the dash.

Any ideas? thanks
