I don't think it says to replace the brake pads at 20,000 miles. As far as I can tell, the service manual only says to inspect the brakes every 4,000 miles. OEM brake pads will most likely last for 40,000 miles, at least that has been my experience.21000 miles on 2012 gw.
maint schedule says change pad at 20,000 miles
any suggestions on quality pads besides oem honda
thank you in advance
