BRAKE FLUID

Bleeding Brake SystemBFS000BK
CAUTION:

Carefully monitor brake fluid level in reservoir tank during
bleeding operation.

Refill with new brake fluid “DOT 3 or DOT 4”. Make sure it is
at least half way at all times while bleeding air out of sys-
tem.

Place a container under master cylinder not to spill brake
fluid.

Turn ignition switch to the OFF and disconnect connector
for ABS actuator and electric unit (control unit) or battery
cable from negative terminal before working.
1. Connect a vinyl tube to rear right brake caliper bleed valve.
2. Fully depress brake pedal 4 or 5 times.
3. With brake pedal depressed, loosen bleed valve to bleed air in
brake line, and then tighten it immediately.
4. Repeat steps 2 and 3 until all of the air is out of the brake line.
5. Tighten bleed valve to the specified torque. Refer to front disc
brake: BR-26, "
Components" , rear disc brake: BR-33, "Compo-
nents" .
6. From step 1 to 5 above, with master cylinder reservoir tank filled
at least half way, bleed air from brake hydraulic line bleed valves
in the following order:
Rear right brake→Front left brake→Rear left brake→Front right brake

It is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of caliper assembly. In this case, suspend cylinder body with wire so as not to stretch
brake hose.

Do not damage piston boot.

If any shim is subject to serious corrosion, replace it with a new one.

Always replace shim and inner shim cover as a set when replacing brake pads.

Keep rotor clean from brake fluid.

Burnish brake contact surface after refinishing or replacing rotors, after replacing pads, or it a soft
pedal occurs at very low mileage. Refer toBR-32, "
BRAKE BURNISHING PROCEDURE" .

der body to torque member.
NOTE:
Using a disc brake piston tool (commercial service tool) to easily
press piston in.
CAUTION:
When replacing pads with new ones, press in piston until
pads can be installed. In this case, carefully monitor brake fluid level in reservoir tank because
brake fluid will return to master cylinder reservoir tank.
