Happy, but not Unimpressed

2007 Lexus GS 350 4dr Sedan AWD (3.5L 6cyl 6A)
This was my first Lexus and was happy with the purchase. I purchased the vehicle for about $47,000 (loaded). My first problem was with the brakes (excessive brake dust and shrieking) They gave me the 2 option 1-better quality, but noisy or 2-less quality and less noise. Not much of an option. Next problem was the driver side rear mirror. It would get stuck at times. The dealer replace with no charge. Mostly I have been happy with the purchase of a Lexus, but expected less of the annoyances for the price of the car. Wanted to know, what was people reaction after the recall fix to replace the fuel lines? The car sounds very loud, especially when accelerating.
The HP is quite impressive as to the internal/exterior styling and color of the vehicle.
I have a problem people that complain about squeeky brakes and brake dust. while i can understand that brake dust can be an annoyance there is a very good reason for the reason it happens. brakes dust is created when the top layer of the pad begins decinitigrating under heavy braking.
the more brakes dust that appears on the wheels, the better the braking is.
while this may sound counter-intuitive to what i just stated, it is far from it.
the surface of the pad is being renewed cleaner and more quickly than with pads that do not create as much dust, while also dissipating heat at the same time. there is also a very easy way to get rid of it....wash your wheels once in a blue moon.
now on to the squeeky brakes.
most of the time when a customer complains about squeeks coming from the brakes, it is usually their fault.
everyone once in a while the brakes need to be used heavily, and this is especially necessary when a fresh set of pads and rotors have been installed.
the technique is called burnishing and it is basically getting the car up to 30 mph and coming to a complete stop quickly.
if you repeat this several times you will eventually smell some material being burnt off the pads.
this smell and some smoke is ok, and is required for burnishing.
this procedure is done in order to heat treat both the pads and rotors which will mate the surfaces together much better.
if you perform this technique without overduing it, it will give you better braking performance, less squeeking and longer brake life.
i hope this was helpful to those wondering about brake squeeking and brake dust.
just make sure you always burnish your brakes in a safe area.
if anyone was wondering, i am a certified Lexus Technician.
