I replaced the front pads a few months ago with NAPA semi-metallics. Brakes were fine for a few days then they started to pulse a little and it got worse. I took the wheels off this weekend and cleaned up the rust on the steel wheel hub and back of the aluminum alloy wheel and re-installed. I've never done this before on any car but I read that it might help. I used a wire brush followed by a Scotchbrite pad on the steel and just the Scotchbrite pad on the aluminum. I followed up wit ha very light coat of high temp brake grease on the areas I just cleaned up.
Afterwards I was very careful about torquing the wheels - first to finger tight, then to 50 ft-lbs on the jack stands in a star pattern. Then I lowered the car and torqued them to spec (100 ft-lbs) in star pattern on the ground.
On the test drive the pulsing was almost gone. Now after driving the car 3 days its back and getting worse - just like before. What could be causing this that removing the wheel and putting it back on improves for a few days? Everything except the pads is original (22 year old) stock parts. Not sure what to try next other than bleeding the brakes.
