Front Brake (For 2Wd) -- Inspection



1. CHECK BRAKE CYLINDER AND PISTON

  1. Check the cylinder bore and piston for rust and scoring.
    If necessary, replace the disc brake cylinder and disc brake piston.



2. CHECK PAD LINING THICKNESS


    Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25

  1. Using a ruler, measure the pad lining thickness.

    Standard thickness:
    10.0 mm (0.394 in.)
    Minimum thickness:
    1.0 mm (0.0394 in.)
    If the pad lining thickness is equal to or less than the minimum, replace the pad.


3. CHECK FRONT DISC BRAKE PAD SUPPORT PLATE

  1. Check the 4 plates as follows. If necessary, replace the plates.

    1. Use brake cleaner to clean the pad of the pad support plate and the surface of the plate that contacts the cylinder mounting. Inspect for deformation, cracks, rust and foreign matter that is difficult to remove.

    2. Use brake cleaner to clean the surface of the cylinder mounting that contacts the pad support plate. After installing the pad support plate to the cylinder mounting, inspect for looseness and deformation.

    3. After installing the pad, inspect if the pad falls off easily (due to the spring force of the pad support plate being insufficient).



4. CHECK DISC THICKNESS


    Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25

  1. Using a micrometer, measure the disc thickness.

    Standard thickness:
    28.0 mm (1.102 in.)
    Minimum thickness:
    26.0 mm (1.024 in.)
    If the disc thickness is less than the minimum, replace the disc.


5. CHECK DISC RUNOUT

  1. Check the front axle hub bearing looseness (HILUX_TGN26 RM000000ZZM00LX_03_0007.html) and front axle hub runout (HILUX_TGN26 RM000000ZZM00LX_03_0008.html).

  1. Install the disc with the 5 hub nuts.

    Torque:
    152 N*m{1550 kgf*cm, 112 ft.*lbf}


    Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25

  1. Using a dial indicator, measure the disc runout 10.0 mm (0.394 in.) from the outer edge of the disc.

    Maximum disc runout:
    0.05 mm (0.00197 in.)
    If the runout is more than the maximum, change the installation position of the disc so that runout is the smallest possible. If the runout is more than the maximum even when the installation position is changed, grind the disc. If the disc thickness is less than the minimum, replace the disc.

  1. Remove the 5 hub nuts and disc.
