vibration when speed reaches about 40 to 45

Hi,

Replacing front brakes and rotors really isn't too hard to do. Make sure to get lifetime pads so you will never have to pay for them again.

You can expect front brakes to last approximately 25,000 miles. However, that can change based on driving habits and terrain.

To get you started, here is a link that explains in general how the job is done. You can use this as a guide.

If you look at the attachments below, they include the directions specific to your vehicle for brake pad and rotor replacement.

I hope this helps. Let me know if you have other questions.

Take care,

Joe
