Q: I have a 2002 Acura TL-S and when I'm driving and apply the brakes I feel a pulsation, but not from the steering wheel. I mostly feel it from my seat. What could be the problem? - Joe A: Hi Joe,  The pulsation feeling coming from the seat and not the steering wheel is usually caused by the rear brakes. It could low pads, warped rotors, and sticking calipers. Bring it by Tire Pros of Frederick and let us take a look at it so we can tell you exactly what is going on.

What could it be? - Jeff A: Jeff,  With a Volkswagon Passat, the hissing noise is usually caused by a bad diaphragm in the master cylinder and you will most likely need a brake master cylinder.

Q: I drive a 2006 Chevy Silverado and just a few days ago I've started smelling a rotten egg smell while I am driving.

Q: I am starting to have a problem turning my key in my ignition. Does the fact that I have multiple keys and keychains on my car keys have anything to do with that? - Sally A: Dear Sally, Yes, having multiple items attached to your car key will start to cause problems with your ignition switch. It can cause premature failure of the tumblers, which are an internal part of the ignition. We here at Tire Pros recommend removing the excess weight so it doesn't ruin the switch.
