I have those old Louise sitting in my garage. They are good enough brakes and you can get replacement pads on Ebay for cheap. My only caution would be that they have a single piston so you need to keep an eye on pad wear. One pad is stationary and if you let it wear down too far your rotor will rub the caliper. The other pad moves with the piston and will have to be turned in every once and a while when your lever gets too close to the bar. Depending on how much you ride and conditions, you shouldn't need to adjust more than once every couple weeks.
