REMOVAL & INSTALLATION




WARNING
If you are not thoroughly familiar with the procedures involved in brake replacement, disassemble and assemble one side at a time, leaving the other wheel intact, as a reference. Even experienced mechanics will usually leave one side intact, because you never know what small part's position you may forget.
