2002 Chevrolet Suburban • V8 2WD Automatic • 196,600 miles
I have a 2002 Chevy Suburban 1500 LS I purchased new. It now has 196,600 miles on it. And, it has original front brake pads! Everytime I have the tires rotated I ask if the brake pads need replaced and every time the answer is no. So, over the Christmas break I decided to look for myself. Sure enough, I have 5 mm of pad left before it reaches the squeal tabs! Now, I have replaced the rear pads twice so I am now on the third set of rear brake pads. Hmmm! Further, about 5 years or so ago my ABS went out. The dealership wanted $1200 to fix. I said no way I'll pump the old fashioned way. The pulled a fuse, had me sign a waiver that the ABS didn't work, and I went on my merry way. Until now! The dealership, I don't think, gave me the full info on the matter as I believe I am getting less than 50% of my stopping power from the front brakes. I know that because the brakes pads are not wearing and due to an almost emergency stop about 6 weeks ago at speeds of around 70 mph. I hit the brakes rather hard for a moment. The rears locked (as I would expect since I my ABS is rendered ineffective). But the rears seemed to lock prematurely as I was on the brakes for less than or right at a second and went from 70 to about 50. The front brakes at that point seemed weak or mushy in hindsight. I have read about old proportion valves and now understand something about brake modulator control valves. My question is. Can you help determine what has exactly failed? Is it a circuit board? Or a valve? What can I do to fix the problem? I am fairly handy so if it is just some control module I feel certain I can install. But if I do does that mean the dealer has to reset parameters? Do you have any thoughts, suggestions, etc?
