I'm looking at the Honda service manual for the 1992 1500 and it states minimum thickness for the front disk 5mm (0.20") front and 6mm (0.24") for the rear. If you have a very discernable lip and the disk still mikes out useable, the lip should be ground off.

My experience with reground brake disks has been poor. I got 120,000 miles on the original disks on my 3/4 Ton pickup. Got the disks ground and needed new disks within 40,000 miles. Pretty much similar luck on my 98 Grand Marquis. I don't think grinding is worth the effort of pulling the wheel off.

Some pads have wear grooves that disappear when the pads used up. Otherwise I tend to consider about 3/32" minimum thickness, 1/8" is definitely getting close to replacement time. What you have now would be okay for a trip as long as 1/8" is the thinnest pad. Often one pad will be thinner than the other on the same caliper, especially if your caliper is frozen and can't move. In that case one pad will be much thinner than it's mate.

Dunno what came on the 1800 but the earlier 'Wings didn't have sintered pads. The only downside of sintered pads is somewhat more wear on the brake disks. Whether it's significant or not I don't know. I've always used organic pads because I believe they do wear less on the disk and I'm satisfied with the braking action I get with them.
