Q: I have a
2012 Honda Accord. When driving on the highway and braking at high
speeds, the brakes vibrate like the anti-lock system is kicking in,
but more pronounced, and there is also vibration in the steering
wheel. I have never had this issue driving around the city. My front
brakes were replaced (not for this issue) and the situation remains
the same. Do you have any ideas on what may be causing this problem?
brake vibrations felt in the steering wheel indicate a problem with
the front wheels. Rear brake problems are usually felt in the seat
of your pants. Warped brake rotors are the No. 1 cause. Warping is
often due to lug nuts not being evenly torqued. Your tech can check
the rotors with a dial indicator. It the rotors are OK, inspect the
suspension bushings, as they often manifest the vibration problem at
higher speeds as you have reported.
Q: I have a
2007 Honda Accord with 50,000 miles. I went for a general checkup
and the dealer said that the upper and lower ball joints were
cracked. They had to order the parts and said that it would cost
$562. I checked for a lower price and a private mechanic
(recommended by a friend) looked at the car and said, "Thereís
nothing wrong with your car." I took it back to the dealer and
got a call from the managerís office saying I was right, there is
nothing wrong with my car. His excuse was that a new, young guy just
out of mechanic school made a mistake. Should I take any further
A: Yes, take
further steps ó lots of them in the direction away from that
dealerís service department. Referrals from friends and associates
are the best way to find a good mechanic, plumber or electrician.
Friends donít have any reason to lie or make excuses. If they did,
they would not remain friends much longer.
Q: I drive a
2007 Hyundai Santa Fe. Iím curious if Iím doing harm to my carís
engine by turning it on to listen to the radio and run the A/C while
on my lunch break for up to one hour five days a week?
Deerfield Beach, Fla.
A: Most of the
harm you are doing is to the environment, not your vehicle. After
all, you see police cars idling for hours with the air conditioning
running along with two-way radios, laptops and other gizmos.
Q: I am a
staunch believer in proper tire pressure and for many years I have
been searching for an answer regarding tire pressure gauges. I have
had many expensive and inexpensive ones and no two gauges read the
same pressure. Can you recommend one?
A: Tire gauges
are not precision scientific instruments, so we are not surprised
that they show different readings. However, the difference is
probably only a couple pounds per square inch between them. Tires
that differ a few pounds from the stated inflation are much less a
problem than underinflated tires. Even factory installed tire
pressure monitoring systems do not trigger a warning until the
inflation is 25 percent below specs. Chose a gauge, any gauge, that
