Question Strange Idle Problem - ? Leak in Brake Cylinder

Having a problem with my idle - generally when car is warming up - if I pull to a quick stop the car will suddenly idle up to 3 to 4K. I can abort the high idle by taking my foot off the brake. I have an 1988 Tenth AE. I cannot find a vacuum leak in the brake system - is it possible the leak is in the brake master cylinder itself ? Thanks John

Braking seems OK - perhaps a a little faded. In the garage - the idle is about 1 K - sometimes about 800. Tried most all the vacuum lines. John
