Id pull the factory service manual and check the torque there. Alldata is usually quite reliable but @mrblane is correct that it's odd they would use just over 18ft/lbs for the rear and 11 for the front. Remember, if you apply locktite you need to drop the torque value you use as it's going to act as a lubricant, and I'm a firm believer in locktite on brake parts.
Here is a chart to help with that but I'd guess in the 30% range should be good.

Another option is to use a 1/4 drive ratchet and go good and tight, call it a day. 8-11 ft/lbs is not much, snug plus a bit more will get you there.
