I have a 97 Chevy Suburban K2500 with a 7.4L engine and I go through front brake pads every 10K to 15K miles. I just discovered a TSB concerning this problem (TSB #99-05-24-001A). However, I'm not sure if replacing the "combination valve" applies to my Suburban. The TSB states that the combination valve to use is P/N#12548265. However, I have called 2 different dealers (parts dept) in my area and both of them say this P/N is for a 1/2-ton with a 5.7L engine. Any help would be greatly appreciated.
