3. Disconnect the brake hose (1) from brake tube (2) at the flare nut (A) using a suitable tool and remove the lock plate (3).
4. Remove the union bolt (A) and the brake hose from the brake caliper. Remove and discard the copper sealing washers.
CAUTION:
Do not reuse copper sealing washers.
5. Remove the lock plate and remove the brake hose.
INSTALLATION
CAUTION:
Do not allow foreign matte r (e.g., dust) and oils other than brake fluid to enter the reservoir tank.
1. Assemble the union bolt (A) and the copper sealing washers (1) to the brake hose and install it as an assembly to the brake cali-
per. Align the brake hose L-pin by aligning it with the brake cali-
per hole, and tighten the union bolt (A) to the specified torque.
CAUTION:
Do not reuse copper sealing washers.
2. Install the brake pipe to the brake hose, temporarily tighten the flare nut by hand until it does not rotate further, and attach the
brake hose to the bracket with the lock plate.
CAUTION:
Check that the brake hoses and pipes are not bent or
twisted.
3. Connect brake hose (1) to brake tube (2). Tighten flare nut (A) to specification and secure to the bracket with lock plate (3).
4. Refill with new brake fluid and perform air bleeding. Refer to BR-
14, "Bleeding Brake System".
CAUTION:
Do not reuse drained brake fluid.
5. Install the wheel and tire. Refer to WT-60, "Road Wheel"
.
6. Perform inspection after installation. Refer to BR-12, "BRAKE
PAD : Inspection".

Front RH brake caliper• Since the cut valve 1 and the suction valve 1 are closed, the front RH brake caliper, master cylinder, and res- ervoir are blocked. This maintains fluid pressure applied on the front RH brake caliper. The pressurization for
the left caliper is controlled separately from the right caliper.
Front LH brake caliper
• Since the cut valve 2 and the suction valve 2 are clos ed, the front LH brake caliper, master cylinder, and res-
ervoir are blocked. This maintains fluid pressure app lied on the front LH brake caliper. The pressurization for
the right caliper is controlled separately from the left caliper.
Rear RH brake caliper
• Since the cut valve 2 and the suction valve 2 are clos ed, the rear RH brake caliper, master cylinder, and res-
