To many problems with the 4 disc setup! I think mainly with the Emergency
brake! It was never hard to set, always mushy, even when brand new. People
would forget to release it and they end up wearing out. Hell they shouldn't
have to be replaced for many years and your at a stop when you set them, and
release them when you go. With the drum brakes, much less problems. A
nice hard parking brake. The drum brakes are a simple setup with a single
large spring basically. It's probably cheaper, and less hassle. It's
really also not needed on the rear of a truck! A high performance sports
car, sure, but not a truck. I would also guess more stopping power for
heavy loads. Much more shoe to drum contact then Pad to Rotor. I believe
Chevy went back to Drums on the 2005 models on up. I have a 2003 with 4
wheel Disc. I've seen a lot of screwed up Parking brakes on Chevy trucks
with 4 wheel disc's. The Drum brakes on the newer Chevy's seems to be
holding up and lasting.

Either better braking or fewer problems with the parking brake setup were
going to be my two guesses. On my 2003 I just bought, while the braking feel
and stopping distance is good, they are not quiet as good as the old 1977 I
used to have. I wonder if they had put bigger rotors how much difference
there would be.
It seems like all high performance sports cars use the four disc setup.
Anybody know about any aftermarket larger rotors ( maybe drilled & slotted)
available?
