Hello, I came here seeking advice.
I own a 2014 Tahoe LTZ.
I had noticed a clunking noise in the front left suspension when riding over bumps or curbs. Upon inspection, I found that the front left sway bar linkage was broken. I had hit a pothole pretty hard a few weeks prior, and assume that was the reason.
I had been also experiencing pulsing in brake pedal when braking, so I inspected the pads and rotors on the front and found an uneven wavy surface on the rotors. I decided that I would do the front brakes with new pads and rotors, and replace both front sway bar linkages.
When doing the brakes, I found that one caliper pin on each side did not glide freely, and was stuck into the caliper bracket pretty good. After getting them out, I cleaned out the hole, bought new pins and boots for the pins, reassembled and completed the brake job. The 2 pins that were stuck, one on each side, still seemed to not slide as freely as the 2 unaffected pins. I took the fast route and did not buy new caliper brackets.
I finished the brake job, took it for a test drive, and the brakes felt fantastic and the front end felt nice and drove true. I then drove 50 miles home, as I was at my friends shop, and at the end of my drive, took the highway exit ramp. Upon applying the brakes at higher speed and more aggressively than on my test drive, I noticed a bad vibration in the front end and brakes. It was not the same as the pulsing I felt before the brake job. The front brakes feel like it sets up a bad vibration, I do not feel this when not braking.
So when I got home, I decided to go ahead and replace the 2 caliper brackets, new pins and boots again, I did this in my driveway. I hoped that the issue was that the slightly catching pins in the brackets were the issue, causing uneven braking. yes, I used the supplied grease for the pins during this entire process. I took the car for a test drive and still had the issue.
I am at loss as to what is going on here. When I did the brakes at my friends shop, I rotated the front tires. He assured me the tires could spin either direction as they were non-directional tread. Could this have caused an issue? I would think it would shake all the time and not just when braking if that where the case.
Anyone have any ideas?
