Rear Drum Brake Shoe Adjustment
Rear brake has self-adjusting mechanism but it does require
adjustment for proper drum to shoe clearance when brake shoe
has been replaced or brake drum has been removed for some
other service.
Adjustment is automatically accomplished by depressing brake
pedal about 30 times with approximately 30 kg (66 Ibs) load after
all parts are installed.
Then check brake drum for dragging and brake system for proper
performance. After lowering vehicle from hoist, brake test should
be performed.
Parking Brake Inspection and Adjustment
INSPECTION
Hold center of parking brake lever grip and pull it up with 20 kg
(44 Ibs) force.
With parking brake lever pulled up as above, count ratchet
notches.
There should be 6 to 8 notches.
Also, check if both right and left rear wheels are locked firmly. To
count number of notches easily, listen to click sounds that ratchet
makes while pulling parking brake lever without pressing its but-
ton.
One click sound corresponds to one notch.NOTE:
Be sure to use particular brake fluid either as indicated
on reservoir cap of that vehicle or recommended in
owner’s manual which comes along with that vehicle.
Use of any other fluid is strictly prohibited.
Fluid level should be between MIN and MAX lines marked
on reservoir.
When brake warning lamp lights sometimes during driv-
ing, replenish fluid to MAX level.
When fluid decreases quickly, inspect brake system for
leakage.
Correct leaky points and then refill to specified level.
CAUTION:
Do not use shock absorber fluid or any other fluid which
contains mineral oil. Do not use a container which has
been used for mineral oil or a container which is wet from
water. Mineral oil will cause swelling and distortion of
rubber parts in hydraulic brake system and water mixed
into brake fluid will lower fluid boiling point. Keep all fluid
containers capped to prevent contamination.

5) After installing, bleed air from system (refer to “Air Bleeding
of Brake System” in this section) and check brake pedal
height and play.
6) Perform brake test and check each installed part for fluid
leakage.

DISASSEMBLY
1) Remove circlip (1).
2) Remove primary piston.
3) [For vehicle with ABS]
Pull out primary piston assembly straight so as not to cause
any damage to inside o cylinder wall.
Pull out secondary piston assembly straight so as not to
cause any damage to inside of cylinder wall and by tapping
flange with a piece of wood or something soft.
4) [For vehicle without ABS]
Remove piston stopper bolt (1). Then remove secondary pis-
ton by blowing compressed air (2) into hole from which pis-
ton stopper bolt was removed.
Be cautions during removal as secondary piston jumps out.
INSPECTION
Inspect all disassembled parts for wear or damage, and
replace parts if necessary.
Inspect master cylinder bore for scoring or corrosion. It is
best to replace corroded cylinder.
Corrosion can be identified as pits or excessive roughness.
2. Master cylinder
NOTE:
Wash disassembled parts with brake fluid.
Do not reuse piston cups.
NOTE:
Polishing bore of master cylinder with cast aluminum
body with anything abrasive is prohibited, as damage to
cylinder bore may occur.

Rinse cylinder in clean brake fluid. Shake excess rinsing
fluid from cylinder. Do not use a cloth to dry cylinder, as lint
from cloth cannot be kept from cylinder bore surfaces.
ASSEMBLY
1) Install secondary piston assembly into cylinder.
2) Install primary piston in cylinder.

CAUTION:
Do not use shock absorber fluid or any other fluid which
contains mineral oil. Do not use container which has
been used for mineral oil or which is wet from water. Min-
eral oil will cause swelling and distortion of rubber parts
in hydraulic brake system and water will mix with brake
fluid, lowering fluid boiling point. Keep all fluid contain-
ers capped to prevent contamination.
