the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Precaution for Brake SystemINFOID:0000000005928387
• Refill using recommended brake fluid. Refer to MA-14.
• Never reuse drained brake fluid.
• Be careful not to splash brake fluid on painted surface of body. If brake fluid is splashed on painted surfaces of body immediately wipe it off with cloth and then wash it away with water.
• To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.
• Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
• Use a flare nut wrench when removing a brake tube and use a flare nut torque wrench when installing a brake tube.
• When installing brake tubes and hoses, be sure to check torque.
• Before working, turn igniti on switch OFF and disconnect connec-
tors of ABS actuator and electric unit (control unit) or the battery
cable from the negative terminal.
• Burnish the new braking surfaces after refinishing or replacing drums or rotors, after replacing p ads or linings, or if a soft pedal
occurs at very low mileage. Refer to BR-34, "
Brake Burnishing
Procedure" .

BRAKE TUBE AND HOSE
• All tubes and hoses 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.
• Brake tubes and hoses are an important safety part. Always disassemble the parts and retighten
their fittings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged part
is detected.
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted surfaces of body , immediately wipe them with cloth and then wash it away with
water.
• Do not bend or twist brake hose sharply, or strongly pull it.
• When removing components, cover brake line connect ions so that dirt, dust, or other foreign mat-
ters do not get in.
• Refill using recommended brake fluid. Refer to MA-14, "
Fluids and Lubricants".
• Never reuse drained brake fluid.

Inspection After InstallationINFOID:0000000005928399
CAUTION:
• Always disassemble the parts and retighten their fitti ngs, if a brake fluid leak is detected. Replace
applicable part with a new one, if damaged part is detected.
• If leak is detected at the connections, retighten it or replace the damaged part.

CAUTION:
• Clean dust on caliper and brake pad with a vacuum dust collector. Do not blow with compressed air.
• While removing brake pad or cylinder body, do not depress brake pedal because piston will pop out.
• It is not necessary to remove torque member mounting bolts and brake hose except for disassembly
or replacement of caliper assembly. In this case, hang cylinder body with a wire so that brake hose is
not under tension.
• Do not damage piston boot.
• If any shim is subject to serious corrosion, replace it with a new one.
• Keep rotor free from brake fluid.
• When replacing brake pad, replace shim with a new one.
