Subject: New Formula Blue® Caliper Part Number Added
Bendix Spicer Foundation Brake is adding a new semi-loaded remanufactured caliper part number to our Formula Blue®
offering. This new Formula Blue® part number is E14685009 and will be available for orders effective January 1st, 2010.
Its’ core group number is 69.
This new caliper assembly can be used interchangeably with the Formula Blue® part number E14685008, replacement
for the Bendix® 2.88” twin-piston caliper – Bendix® part number 55250. Although the assemblies are interchangeable
the component designs of the E14685009 and E14685008 are not the same, including machining differences which
do not allow interchangeability of maintenance kits, components and therefore cores.
The new Formula Blue® caliper, part number E14685009, is similar to the pre-1989 design with phenolic pistons and
a unique “soft boot”. This differs from the Formula Blue® part number E14685008 (replaces Bendix® part number
55250) which has phenolic pistons and a “hard boot” with a metal insert. Caliper part number E14685009 is being
made available for customers returning the ‘soft’ boot cores. Returning such cores will establish core eligibility in
core group number 69.
Refer to Technical Bulletin TCH-020-018 for additional technical information pertaining to the calipers.
