Isuzu N Series 2008 Owner's Manual page 421

If the brake shoe linings wear out beyond their usable limit, not only will the brake
performance be impaired, but brake components could also fail.
WARNING
• Do not drive with brake shoe linings worn out beyond the limit. Excessively
worn brake shoe linings may cause breakdown of brake components and poor
braking performance. This is very dangerous.

SERVICE AND MAINTENANCE
Drum Brakes
Brake Shoe Linings
Checking Brake Shoe Linings for
Wear
1. Remove the rubber plug from the
inspection hole in the backing plate.
2. Check that brake shoe lining of
sufficient thickness is remaining. Also
check the side surfaces of the lining
for cracks, flaking or other damage.
3. The wear limit for bonded brake
shoe linings is when the thickness is
reduced to 1 mm (0.04 in) and the
wear limit for riveted linings is when
the step is worn away. The lining
must be replaced if it is worn beyond
the wear limit or there are cracks or
flaking on the side surfaces. Have
the replacement carried out by the
nearest Isuzu Dealer.
Adjustment of Drum-to-Lining Gap
(Model with Automatic Adjuster)
1. Press down the brake pedal as far as
it goes.
2. Repeating Step 1 above until there
is no change in pedal stroke will
automatically adjust the drum-to-lining
gap to a certain extent. After this,
repeated braking while driving will
automatically adjust the gap.
