3. With brake pedal depressed, loosen bleed valve to let the air out, and then tighten it immediately.
4. Repeat steps 2, 3 until no more air comes out.
5. Tighten bleed valve to specified torque. Refer to BR-25, "
Component" (front disc brake), BR-35, "Compo-
nent" (rear drum brake).
6. Following the steps 1 to 5 above, with master cylinder reservoir tank filled at least half way, bleed air from

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.
Front Brake Tube and HoseINFOID:0000000005396984
REMOVAL
1. Drain brake fluid. Refer to BR-9, "Drain and Refill".
2. Using a flare nut wrench, remove brake tube from brake hose.
3. Remove union bolt and discard the copper washers. CAUTION:
Do not reuse copper washers
4. Remove brake hose from caliper assembly.
5. Remove lock plate, and remove brake hose.
INSTALLATION
1. Assemble union bolt and new copper washers on to brake hose. CAUTION:
Do not reuse copper washers
2. Position the L-shape metal fitting of the brake hose to the brake caliper assembly positioning hole.
3. Tighten union bolt to the specified torque. Refer to BR-11,
"Hydraulic Circuit".
4. Connect brake hose to brake tube, and temporarily tighten flare nut by hand as much as possible.
5. Secure brake hose and brake tube with lock plates.
6. Tighten flare nut to the specified torque with a suitable tool. Refer to BR-11, "
Hydraulic Circuit".
7. Bleed the air from the brake hydraulic system. Refer to BR-9, "
Bleeding Brake System".
Rear Brake Tube and HoseINFOID:0000000005396985

2. Disconnect brake lines from dual proportioning valve. • Mark brake lines for installation.
3. Remove dual proportioning valve bolt and dual proportioning valve.
4. Remove two bolts and bracket.
Installation
Installation is in the reverse order of removal.
• When installing brake lines to the dual proportioning valve, tighten to specifications. Refer to BR-11,
"Hydraulic Circuit".
InspectionINFOID:0000000005396988
CAUTION:
• Carefully monitor brake fluid level at master cylinder.
• Use the recommended new brake fluid. Refer to MA-14, "
Fluids and Lubricants".
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on paint areas, wash it away with water immediately.
1. Connect a suitable brake fluid pressure gauge to air bleeders of front and rear brakes on either LH and RH side.
2. Bleed air from the brake fluid pressure gauge.
3. Check fluid pressure specific ation by depressing the brake pedal.
• If output pressure is out of specification, replace the dual proportioning valve.
Unit: kPa (kg/cm2, psi)
4. Bleed air after disconnecting the brake fluid pressure gauge. Refer to BR-9, "Bleeding Brake System".

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.
