The brake pedal becomes very stiff suddenly. The first time, I kick it, it was smooth as I hear a click sound. The second and third, it was ok after I step on the gas. It just happens occasionally. I really don't understand.
As someone knows it the brake booster, i.e. worn diaphragm, runs out which will cause this matter occasionally? Or vaccum lining, brake lining, check value nalfunction....
My old car has problem of its rear drum brake. I think both of them were worn. I know it, so I use the front disc brake to stop the car. Recently, one of the drum was fratured. this thing can cause hard brake pedal occasionally?
urgent helps!!! what is the problem? why it happens occasionally?
many thanks for any suggestion.

By the way, all these were happned after I changed the winter tires. Is there something wrong? ]]> Lumina APV jerpear http://www.automotiveforums.com/vbulletin/showthread.php?t=970818
