2009 Mercury Mariner Brake Pads Parts Questions & Experts Answers

• Q: How to service and repair brake pads on 2009 Mercury Mariner?

  A: Begin brake pad servicing by only using brake fluid that meets manufacturer requirements and avoid previously drained fluid to stop contamination and damage. A suitable suction device should be used to draw fluid out of the master cylinder reservoir until its volume reaches half of the total capacity. Next proceed to take away both wheel and tire. Gently free the brake pad anti-rattle spring from its position but avoid using tools to protect it. The left-hand side spring requires force at the center and outward pull to release its lower portion followed by rotating it out of the brake caliper. Similar to the left-hand side proceed with one spring removal from the upper part of the assembly. Check that the caliper is not supported from the brake hose then take out the two guide pin bushing caps and two brake caliper guide pin bolts before putting the caliper on mechanic's wire for support. Check brake pads for wear then contamination and replace them when needed before removing the contaminated pads from the brake system. New pad installation requires a C-clamp along with an old brake pad which allows compressing the caliper piston into the caliper while taking precautions for the piston and boots. Check the brake disc for damage then proceed to reface or replace it as necessary. The brake caliper anchor plate installation process requires brake parts cleaner to clean and dry the surface while the four brake pad contact points need application of specified lubricant. First correct the position of the brake flexible hose and then place brake pads inside the caliper before mounting it onto the anchor plate. Fasten the two brake caliper guide pin bolts and bushing caps by using 50 Nm (37 lb-ft) of torque. Place the brake pad anti-rattle spring by feeding its tab within the caliper cavity, rotating it while directing left into upper then right into lower spaces. Latch and position this element onto the anchor plate after manually pushing it downward and inward. Check whether the spring latches properly by tugging on it before you install the tire along with wheel. After filling the brake master cylinder reservoir with clean specified brake fluid it is important to test the brake operation by applying the brakes repeatedly until correct functionality is achieved.
