BRAKE SHOES
In all cases of brake complaints denoting actual brake
lining or shoe failure, the brake drums should be re ­
moved and before disassembly of the shoes from the
flange plate, all linings should be inspected for wear,
improper alignment, causing uneven wear or oil and
grease on the linings. If any of these conditions exist, it
will be necessary to replace or reline the shoes. If, in
checking the linings, it is noticed that they have the
appearance of being glazed, this is a normal wearing
condition with the type lining used. It may be necessary
to use a wire brush or an abrasive on the lining to des­
troy this glazed surface.
When brake lining replacement is necessary, replace
the shoes and linings on both front wheels or both rear
wheels. On low mileage vehicles where a grease seal
leak or minor chatter has developed, replacement of both
shoes on that wheel is perm issible. In no case should a
single shoe or lining be replaced.
