BRAKE FLUID
BRAKE FLUID
On Board InspectionINFOID:0000000001716919
CHECKING BRAKE FLUID LEVEL
 Make sure the fluid level in the reservoir tank is within the standard
(between MAX and MIN lines).
 Visually check around the reservoir tank for fluid leakage.
 If fluid level is excessively low, check brake system for fluid leak-
age.
 Release parking brake lever and see if brake warning lamp goes
off. If not, check brake system for fluid leakage.
Drain and RefillINFOID:0000000001716920
CAUTION:
 Refill using recommended brake fluid. Refer to MA-19, "
Fluids and Lubricants".
 Never reuse drained brake fluid.
 Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, immediately wipe them with cloth and wash it away with water.
 Before working, disconnect connectors of ABS actuator and electric unit (control unit) or battery
cable from the negative terminal.
1. Connect a vinyl tube to bleed valve.
2. Depress the brake pedal, loosen the bleed valve, and gradually
remove the brake fluid.
3. Clean inside of reservoir tank, and refill with new brake fluid.
4. Loosen bleed valve, depress brake pedal slowly to full stroke
and then release it. Repeat the procedure every 2 or 3 seconds
until the new brake fluid comes out, then close the bleed valve
while depressing the brake pedal. Repeat the same procedure
for each wheel.
5. Bleed air. Refer to BR-8, "
Bleeding Brake System" .
Bleeding Brake SystemINFOID:0000000001716921
CAUTION:
 While bleeding, pay attention to master cylinder fluid level.
 Before working, disconnect connectors of ABS actuator and electric unit (control unit) or the battery
cable from the negative terminal.
1. Connect a vinyl tube to the rear right bleed valve.
2. Fully depress brake pedal 4 to 5 times.
