I recently discovered that my brake lights haven't been working properly since I did a front power disc conversion. When the engine was off, they worked fine (which is how I originally checked their function), but with engine running, the lights wouldn't come on until the pedal was mashed way down. Apparently, the return spring on the brake light switch was so stiff that with the booster assist, the wasn't enough pressure on the pedal assembly to overcome the spring pressure and activate the brake lights until the pedal pushed down to near it's limit. I fixed the problem by disassembling the switch (i.e. bending the tabs that hold everthing together) and replacing the original spring with a softer one of the same diameter that I found in the garage. I don't know if this is a common problem (or a common fix that everyone else knows about already), but I thought I'd pass it along in case it helps someone else.
