      <title>HANG THOSE REBUILTS AND MOVE 'EM OUT FASTER!</title>
      <link>https://trid.trb.org/View/197006</link>
      <description><![CDATA[This article discusses the pros and cons of using remanufactured disc brake calipers in auto repair shops.  The main advantages are that rebuilt calipers can significantly increase repair bay output while cutting down on warranty exposure.  There can be inventory advantages, too with fewer part numbers to keep track of since rebuilt calipers have all rubber parts already installed.  Inventory, however, can also be a big drawback, since carrying costs might easily triple. A list of suppliers is included with this article.]]></description>

      <title>BRAKE NOISE</title>
      <link>https://trid.trb.org/View/197035</link>
      <description><![CDATA[This article describes disc brake squeal as a noise that occurs at the upper range of human hearing which many but not all people with apparently normal hearing can hear.  Research at Bendix Corporation employs sophisticated aural testing equipment to isolate, identify and measure brake noises.  Tests show that the noise source is the entire system, including the friction material, pad shape, and configuration of the caliper and rotor.  Squeal has been reduced by switching the friction material, altering the pad shape, and cutting slots in the rotor.  An insert with this article is entitled "Rotor's composition can lower noise, wear."]]></description>

      <title>DUST BOOT</title>
      <link>https://trid.trb.org/View/196111</link>
      <description><![CDATA[It would seem that installing caliper dust boots is a straightforward operation.  However, the real world situation is that a lot of dust boots are not properly installed, and many calipers go back into service with boots that are unseated.  The dust boot may not seem like a critical item, but unless it is correctly seated all around and in good condition (no cuts), dirt and moisture can get into the piston bore.  This article deals with dust boot replacement with the three basic types of dust boots, the integral ring type, the external ring type and the groove lip boot.]]></description>

      <title>TROUBLESHOOTING YOUR BRAKE SYSTEM</title>
      <link>https://trid.trb.org/View/196118</link>
      <description><![CDATA[Brake-system maintenance is probably the most critical part of vehicle care.  While the car that won't go may frustrate you, the car that won't stop can kill you.  To avoid the complications that can occur when pads or shoes wear beyond limits, check brake condition at regular intervals.  Of course, brakes should always be inspected when their application results in noise or when the vehicle pulls to one side during braking.  Some late-model GM and Ford products have brake-wear warning devices.  But in most cases, the only way to determine pad or shoe condition is to remove the disc caliper or the drum and inspect the friction material.  Thus, this article discusses disc brake basics, including caliper removal, inspection and diagnosis, reassembly, and drum brake basics, including inspection, disassembly, and reassembly.]]></description>
