BRAKE DRUMS
ALLIANCE TRUCK PARTS
BRAKE SHOES AND KITS
Brakes are serious business and so is the choice between imported and U.S.-
manufactured brake drums. While imported drums may be cheaper to purchase,
their potential failure points can dramatically affect long-term durability —
costing you time and money. That’s why Alliance brake drums are cast and
machined in the U.S. for durable, smooth braking operation you can rely on.

BRAKE CHAMBERS
Alliance brake chambers are designed to provide years of safe, dependable operation
for service, parking or emergency braking applications. These spring brakes and service
chambers feature rugged construction, heavy-gauge housings and steel components to
reduce corrosion and potential equipment failure.
THE FACTS: WHY RUST-JACKING
IS A SERIOUS PROBLEM
Rust-jacking is caused by corrosive anti-icing
highway chemicals combined with thawing and
freezing moisture that penetrates the brake shoe
coating and causes rust to build up on the brake
shoe table. Rust-jacking is found most often
where intense brake heat cannot dry out the
shoe table. Typically, this occurs in front shoes.

lining cracks. No matter how thin the lining is,
once cracked, it’s unsafe and must be replaced.
