Rear Brake (For 2Wd) -- Inspection



1. CHECK BRAKE DRUM INSIDE DIAMETER


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

  1. Using a drum gauge or equivalent, measure the inside diameter of the brake drum.

    Standard inside diameter:
    254.0 mm (10.000 in.)
    Maximum inside diameter:
    256.0 mm (10.079 in.)
    If the inside diameter is more than the maximum, replace the brake drum.


2. CHECK BRAKE SHOE LINING THICKNESS


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

  1. Using a ruler, measure the thickness of the shoe lining.

    Standard thickness:
    5.1 mm (0.201 in.)
    Minimum thickness:
    1.0 mm (0.0394 in.)
    If the lining thickness is less than the minimum value, or if there is any severe or uneven wear, replace the brake shoe.

    If the contact between the drum and the shoe lining is improper, make adjustments using a brake shoe grinder or replace the brake shoe assembly.
