WHEN RIVETING BRAKE LINING
USE ROLL SET
ROLL SET EXPANDS RIVET INTO
HOLE BEFORE UPSETTING.

prevent the initial rusting problem. Before riveting, clamp the
blocks tightly to the shoe, placing the clamps close to the
rivet holes. Be sure the holes in the blocks and the shoes
are exactly matched.
Never shim the brake linings as this will only cause problems.
Brake noise may result because of cracked and loose lining
since a tight installation is not possible. The inside surface
of the lining is the correct arc to match the shoe table, and
the rivet holes in the linings will only line up with holes in the
shoes when they are in direct contact.
The sequence of riveting should be such that the center of
the block is attached first and then the ends.

NOT STAR SET
START SET SPLITS TUBE AND
RIVET DOES NOT FILL HOLE
Some brake failures result from the use of rivets which are
too short, too long, or the wrong diameter. Incorrect setting
of the riveting machine may induce other types of failures.
The correct length rivet must be selected for each application.
A variation in shoe table thickness may require a different
length rivet.
The solid portion of the rivet should end just at the inner
surface of the shoe. The hollow portion of the rivet should
protrude past the inner surface of the shoe.
The proper size rivet must be used to completely fill the rivet
hole.
Brass plated steel rivets are recommended but cartridge
brass rivets can be used if so desired.
#10-10 RIVETS
The riveting machine must be adjusted so that the roll of the
rivet is complete, but the rivet should not split. Always use a
roll set, never a star set, when riveting brake linings. A star
set does not compress the rivet and expand it to fill the
hole. Consequently, the lining may work loose in service.
