97 f150 brake pedal is hard to press during winter, and takes forever to stop truck...Dangerously slow stopping. It's soft during the summer and warm weather, but often goes all the way to the floor.... Sometimes locks up randomly, but mostly when it's raining.
Do you think it's the brake booster, the master cylinder, or perhaps a vaccuume issue?
Love the channel Scotty. My friends and I often play your videos in the shop with the audio broadcast over the speaker sytem when we are working on our projects.
Thanks for the help over the years.
