Carefully monitor brake fluid level in reservoir tank during bleeding operation.
Refill with new brake fluid “DOT 3”. Make sure it is at least half
way at all times while bleeding air out of system.
Place a container under master cylinder not to spill brake fluid.
Turn ignition switch OFF and disconnect ABS actuator and
electric unit (control unit) or battery negative terminal.
Bleed air in the following order. Right rear brake → Left front
brake → Left rear brake → Right front brake
1. Connect a transparent vinyl tube to bleed valve.
2. Fully depress brake pedal several times.
3. With brake pedal depressed, open bleed valve to release air.
4. Close bleed valve.
5. Release brake pedal slowly.
6. Repeat steps 2, through 5, until clear brake fluid comes out of bleed valve.

BRAKE TUBE AND HOSE
BRAKE TUBE AND HOSE
Hydraulic CircuitINFOID:0000000001327613
CAUTION:
All brake hoses and tubes must be free from excessive bending, twisting and pulling.
Make sure there is no interference with other part s when turning steering both clockwise and coun-
terclockwise.
The brake tubes and hoses is an important safety pa rt. If a brake fluid leak is detected, always disas-
semble the parts. Replace applicable part with a new one, if necessary.
Be careful not to splash brake fluid on painted areas; it way cause paint damage. If brake fluid is
splashed on painted surfaces of bo dy, immediately wipe it off and them wash it away with water
immediately.
Do not bend or twist brake hose sharply, or strongly pull it.
When removing components, cover br ake line connections so that no dirt, no dust, or other foreign
matter gets in.
Refill with new brake fluid “ DOT 3 ”.
Do not reuse drained brake fluid.

2. Using a flare nut wrench, remove brake tube from brake hose.
3. Remove union bolt and remove brake hose from caliper assembly.
4. Remove lock plate and remove brake hose from vehicle.
INSTALLATION
1. Position brake hose by aligning with the protrusion on caliper assembly, and them tighten union bolt to the specified torque.
CAUTION:

BRAKE BOOSTER
BRAKE BOOSTER
On-Vehicle ServiceINFOID:0000000001327621
OPERATING CHECK
With engine stopped, change the vacuum to the atmospheric pres-
sure by depressing brake pedal several times. Then with brake
pedal fully depressed, start engine and when the vacuum pressure
reaches the standard, make sure the clearance between brake pedal
and floor panel decreases.
CAUTION:
Depressing pedal interval is approximately 5 seconds.
AIRTIGHT CHECK
Run engine at idle for approximately 1 minute, and stop it afterapplying vacuum to booster. Depress brake pedal normally to
change the vacuum to the atmospheric pressure. Make sure dis-
tance between brake pedal and floor panel gradually increases.
Depress brake pedal while engine is running, and stop engine with
pedal depressed. The pedal stroke should not change after holding
pedal down for 30 seconds.
CAUTION:
Depressing brake pedal is interval is approximately at intervals
5 seconds.
