I have found that weaving side to side while using my legs to slow the cranks down helps in addition to using the front brake. The situation depends on how fast I am going vs what's going on. 19mph down the road and you hit a yellow light that you know you can't make, I start weaving to help slow myself down. I don't skid, I don't know how to skid, I don't want to skid. One method you can look into is the skip stop. I haven't tried this, so I don't know how effective it is.
