New Source for 240Z Aluminum Brake Drums

If you're in a 280, I'm sure the extra weight of the chassis would be harder on various components of your brake system, and if I remember right the rear brakes on a 280 use a different wheel cylinder, and attach a little differently. Maybe it's a bit more efficient than a 240's, and you are getting better braking/generating more heat on of your drums than we are.

The 1977-78 280Z uses a different rear brake configuration (backing plate, wheel cyl, shoes, etc.) but the drums are the same. I discovered that when I ordered new shoes for my 75 280Z and discovered that they wouldn't fit because the PO changed over to the 77-78 setup.

That's correct. The later model wheel cylinder has 2 pistons and pushes both shoes. The earlier Z''s wheel cylinder had a single piston, and pushed on the one active shoe, tightening the static shoe as it got tighter. The later setup will give you better braking, which we are sorely lacking compared to our competitors with 4 wheel disks.

2 pistons might work a bit better, but still does not work good.

my extra 200 lbs I am sure does not help the situation. My fronts seem to work good with 2 3" duct, but I really have a problem with the rear drums.

I am excited that we can buy drums again, I was tired of bidding on used drums on e-bay.
