Wheel Cylinder: Disassembly

WARNING: This page is about a different car, the 2004 Mazda Tribute, 2003 Mazda Tribute, and 2002 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Numbers in parenthesis refer to numbers in illustration.
  1. Remove the rear wheel cylinder. See WHEEL CYLINDER  .
    CAUTION: Do not use denatured alcohol for flushing the brake system or cleaning assemblies where alcohol could be trapped. If denatured alcohol is trapped, it can cause eventual failure of rubber components in the system.
    CAUTION: Never allow any petroleum product or mineral oil to contact the inside of a brake hydraulic system. Mineral oil and petroleum products deteriorate the natural rubber seals used in brake hydraulic system. If a brake system becomes contaminated, it must be flushed with clean brake fluid and all new rubber seals and flex hoses must be installed. Use DOT 3 brake fluid.
  2. Disassemble the rear wheel cylinder. See Fig 1 . Remove the bleeder screw cap (1). Remove the bleeder screw (2). Remove the dust boots (3). Remove the pistons and piston seals (4). Remove the spring (5). Disassemble as order in illustration.
  3. Inspect the rear wheel cylinder bore for wear, rust or pits. If any of these conditions exist, install a new wheel cylinder.
