By installing any new / rebuilt part it does reduce the possibility of that part failing as soon as a used one installed (with no information on how much it was used) IMO. Especially a known to fail often part. 75% would be a safe percentage. I would spend the extra $50.00 to have the lifetime warranty on this part. That is if I wanted the ABS to work and it didn't because of this part. Just as you, That is my personal opinion and some people can't handle that there is other options that are correct also..
