I was hoping to get some input on this strange problem I have been experiencing. My brakes grab noticeably better when the weather is cold and humid (like close to freezing rain kinda weather). It only works for the first 2-3 stops, then the brakes go back to their normal, unremarkable, squishy self (presumably because the system is more warm?). I'd love to have my brakes always work as well as they do on the first couple stops on nasty days. Anyone have any idea why this might be happening? Any ideas on how I could permanently make the system as good as it is when it's cold and humid? Background info. is that I suck all the fluid out of my master cylinder 1-2x a year and top off with a fresh (newly opened) bottle of DOT4, so I don't think there's a moisture problem in the system. Thanks in advance for any input!
