On February 3, 2010, NHTSA published a notice in the Federal
Register at 75
FR 5553 proposing to amend FMVSS 116, Motor Vehicle Brake Fluids, so that
brake fluids would be tested with ethylene, propylene, and diene terpolymer
(EPDM) rubber, as this type of rubber is increasingly being used in brake fluid
seals. The NPRM also updates references
to SAE and ASTM
standards and corrects minor errors in the standard.
As proposed, the amended rule would take effect 180 days
after publication of the final rule.
Comments on the NPRM are due April 5, 2010.
