Brake Caliper/Mounting Plate Wear Adjustment Front Dayton-Walther

The brake caliper V-ways and the brake caliper mounting plate support rails will wear and eventually cause the brake caliper to fit loosely. Dayton-Walther brakes use shims to adjust for this wear. Follow these steps when replacing the linings.


    Object Number: 260919 Size: SH
  1. Remove the brake caliper retainer screw (1).
  2. Tap out the brake caliper retainer (4) and the brake caliper retainer spring (2).
  3. Remove the brake caliper (6). Refer to Front Brake Caliper Replacement .

    4. Object Number: 209264 Size: SH
  4. Clean the V-way surfaces of the brake caliper (5) with a wire brush.

    5. File smooth any nicks and gouges.

  5. Clean the support rail surfaces of the brake caliper mounting plate (4) with a wire brush.

    6. File smooth any nicks and gouges.

  6. Temporarily mount the brake caliper on the brake caliper mounting plate.
  7. Install a new brake caliper retainer (3).
  8. Install the brake caliper retainer bolt (1).
  9. Use a screwdriver in order to turn the vanes of the brake rotor in the forward direction. This will jam the brake caliper support rail in contact with the brake caliper mounting plate support rail.
  10. Measure the brake caliper retainer gap with a feeler gauge laid full length in the gap.
    11. • If the gap is 0.89 mm (0.035 in) or less then no shim is needed.
    • If the gap is more than 0.89 mm (0.035 in), add shims.
    • If the gap is greater than 2.92 mm (0.115 in), replace the brake caliper mounting plate. Refer to Front Brake Caliper Replacement .
  11. Select the correct size shim.
    12. • If the gap measurement is 0.91-1.40 mm (0.036-0.055 in), use a shim thickness of 0.51 mm (0.020 in).
    • If the gap measurement is 1.42-1.91 mm (0.056-0.075 in), use a shim thickness of 1.07 mm (0.042 in).
    • If the gap measurement is 1.93-2.41 mm (0.076-0.095 in), use a shim thickness of 1.47 mm (0.058 in).
    • If the gap measurement is 2.44-2.92 mm (0.096-0.115 in), use a shim thickness of 1.83 mm (0.072 in).

    Object Number: 276158 Size: SH
  12. Remove the brake caliper retainer bolt.
  13. Remove the brake caliper retainer.
  14. Remove the brake caliper spring.

    15. Object Number: 22098 Size: SH
  15. Lift the forward end of the brake caliper enough in order to provide clearance between the brake caliper and the brake caliper mounting plate support rail (1).

    16. This permits installation of the shim (2).

    Important: Place the shim with the widest side of the shim fitting against the widest surface of the brake caliper mounting plate.

  16. Lower the brake caliper to the caliper's original position with the shim in place.
  17. Install the brake caliper. Refer to Front Brake Caliper Replacement .
