My 2005 GMC Sierra 1500 Pickup with 60,700 miles had severe brake
vibrations.
I put it in for service at a very trusted repair center.
He called and said my entire brake system was rusted and in dangerous
condition.
I do mostly highway driving and usually need brakes at 90,000 to
100,000 mile.
This is my sixth GM half-ton pickup since 1979.

Rusting brake rotors and calipers caused excessive uneven wear of rear
and front brake pads. I was hearing a squeal that sounded as though
the pads were worn. The inside side of rear rotors were destroyed, due
to a rusted hung up brake pad, that was dragging on the rotor. The
outside of the rotor was rusted so badly the metal flaked off in
chucks. The front brake rotors were rusted pitted and need to be
replaced.
As a result, I had to replace all the rotors, brakes and rebuild the
calipers.
GM should be ashamed of the parts they are using. My mechanic said he
has seen this rust problem on most of the new style GM trucks. This
repair cost me over $1800.00

My wife's car is a 1998 Toyota Camry with 250,000 with no major
repairs. I was so happy with it, we bought a 2004 Camry.
THE NEXT TRUCK I BUY WILL BE A TOYOTA!
