remove tire/wheel. remove brake caliper/ bracket. remove center axle nut. remove 4-hub nuts. hub should come out with hands. Grease and red-torque all appropriate parts during reassembly.

Service the stability system. Thats why the lights are on. The vibration is telling you this too..

You have to remove the caliper and then the pad holder install your new pads inthe holder put it back on squeese the pads against the rotor compress your caliper in re-install and make sure you pump the brake pedal several times before driving.

Well I would post a solution but I feel like "fixya" should pay me for telling them. It kind of bothered me that I was going to have to pay for assistance. Usually someone will look at your vehicle for free just to figure out the problem.

I had a similiar problem. My car would actually pull to the left it was so bad. I took it to the dealer several times and they could not fix it. Turn out they where simply driving the car around the auto mall circle a couple of times. My wife took them on a 30 mile trip when it finally happened with a service tech in the car. The guy freaked out and had my wife take the car rite back and the service center took possession of the car and gave her a free rental even though the car was not under warranty. Turns out it was a faulty computer brake module, when it goes bad it ingages the traction control/stability control system when it is not needed. Not sure if this is your problem but it is something to think about.

if your vibration comes and goes with different speeds, most likely problem is balance in tires/wheels. a bent wheel often vibrates more with higher speeds. if the vibration is stong in the steering wheel, the problem is normally in the front end, if you feel in more in the seat or body of the car then look to the rear end.
