Fewer Lancer brake pad shims
Mitsubishi notes that they’ve changed the rear disc brake pad shim requirement for the 2008-2009 Lancer. The number of rear brake pad shims (per wheel location) has been reduced from four to one.
A single shim is now installed at the outer pad only. The inner pad now uses no shims. The bulletin also applies to earlier models where the shims are replaced with new parts.
