Steering hydrulic assist connections at booster constantly leak from day one. They have been replaced and still leak. Which in turn cause a decrease in brake pressure.
I have had the lower steering arm replaced three times due to a bad bushing. Once under warranty & twice I had to pay for it which is over $300. 00 each time. This is not an uncommon problem with the Chevrolet & GMC trucks. This is only noticeable while in motion.
