2009 Mercury Mariner Brake Shoe Parts Questions & Experts Answers

• Q: Should new brake shoes or pads always be installed at both ends of an axle when servicing brake shoes on 2009 Mercury Mariner?

  A: Replacement of brake shoes or pads must happen at both brake shoes or pads ends to stop unintended vehicle pulling because improper installation of new components leads to unsafe braking conditions causing severe personal harm. Before installing new rear brake shoes with their accompanying linings technicians should completely resurface the brake drums so glazing disappears and both sides of the friction surface become balanced and any out-of-round or bell conditions get addressed. The brake shoe retaining springs together with the two pins must be removed after separating the brake drum. This process requires removal of the upper return spring last. The removal process starts with self-adjuster and spring assembly followed by lower return spring followed by trailing brake shoe combined with the parking brake actuator lever assembly leading up to the final step of taking out leading brake shoe. Use brake parts cleaner to clean and dry brake shoe contact points before applying specified silicone grease as a thin coating to these points. The self-adjuster needs to be positioned all the way back to let you install the brake drum. The completion stage includes reversing the current operation while readjusting the rear brake shoes if needed.
