ABS light on?

ABS braking issues intermittently, which affects braking (car will not stop normally). Replaced front left ABS wheel sensor, which made the ABS/Check Engine lights go off. However, it happened again that same day and the lights came back on and I nearly had an accident from not being able to stop. The ABS light does not stay on, but the Check Engine light does.

I had the dealer pull the codes, but they want $1600 for brake control module & RF wheel sensor, as well as misc work to address them all and told me it's possible this will not solve the problems. Should I replace the right front wheel speed sensor?

Any suggestions to address the codes below are greatly appreciated:C100 - C1201 - C1202 - C1203 - C1204 - C1205 - C1208 - C1211
