THE POWER OF PLATINUM PROTECTS AGAINST
RUST-JACKING FOR 3-YEARS/300,000-MILES.
It’s hard to improve on an original –
especially a game changing original
such as PlatinumShield, but that’s exactly what our team of
engineers did. And it’s going to pay even bigger dividends for
Meritor
®
customers.
At Meritor, we continue to invest in our PlatinumShield
technology to improve performance and durability. Meritor
engineers are continually conducting research and testing to
discover ways to improve our PlatinumShield coating process.
The result is PlatinumShield III, our third-generation coating
withadvanced engineering that maximizes resistance to rust-
jacking.
In developing PlatinumShield III coating, our aftermarket
engineering team discovered a refinement in the process
that provides superior adhesion of the coating to the surface
of the shoe. Superior adhesion enables the coating to protect
the brake shoe for a significantly longer time on the road,
increasing the shoe’s durability to withstand the corrosion
caused by highway de-icing chemicals. The result is a
quantum leap in technological performance that creates
a new standard of brake-shoe durability. PlatinumShield III
coating provides unsurpassed resistance to rust-jacking and
corrosion while extending the life of your brakes.
Why Does Rust-Jacking Require a Long-Lasting
Solution?
• Rust-jacking often shortens the life of brake shoes and
brake linings, preventing truck operators from getting
the full life out of their equipment.
• Rust-jacking is a field condition caused by harsh anti-icing
liquids in winter road solvents, combined with thawing and
freezing moisture that penetrates the brake shoe coating and
causes rust to build up on the
brake shoe table.
• As rust builds up, it pushes
outward against the lining,
“jacking” it up between the
rivets, until the lining cracks.
• Once the lining cracks, driving
is unsafe, and the lining must
be replaced, cutting short the
brake shoe life and denying truck
operators its full value – often
with a thick amount of lining
remaining.
• Rust-jacking is found most often where intense brake heat
cannot dry out the shoe table. Typically, it occurs in front
shoes.
How Did Our Brake Engineers Solve This Longtime
Rust-Jacking Problem?
Introduced in 2009, PlatinumShield was created to address a
real-world corrosion problem that had long beset the trucking
industry. In order to develop a real-world solution, our brake
experts re-created actual road conditions. We subjected lined
brake shoes to brake applications on a dynamometer before
subjecting them to a salt spray test. That way, brake shoes
reached the salt spray test with wear and tear that more
closely approximated actual highway results.
Next, in our ASTM B-117 salt spray test, brake shoes were
sprayed with modern anti-icing road solvents and salt water
for 400 hours. We observed how rust forms on brake shoe
tables, and tested the
corrosion-resistance of
countless paints and
coatings.
