abs and its impact on brake maintenance

1. None - you should do this periodically anyway.
2. New pads should have no effect other than the braking performance increase/decrease associated with a different pad compound.
3. As long as that's all you replace, you may see some change in ABS due to stiffer brake lines (more pronounced pulses under ABS).

so no.3 is not a problem as well as long as i use the same brake hose from yamaha?
