sounds like you need to adjust for a bit more toe-in. the forward edge of the brakes should touch first, when the rearward edges are still about 1/8" out, give or take. when the brakes flex under the force of braking, it pulls the shoes forward which takes out this toe-in. if there's no toe-in to start with, then they oscillate and make the loud squeal.

also cleaning any old brake pad material off the rim, I use paint thinner or alcohol on a cloth rag.
