BRAKE FLUID
On Board Inspection INFOID:0000000004305892
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 leaks.
• If fluid level is excessively low, check brake system for fluid leaks.
• Release parking brake lever and see if brake warning lamp goes
off. If not, check brake system for fluid leaks.
Drain and Refill INFOID:0000000004305893
CAUTION:
• Refill using recommended brake fluid. Refer to MA-14, " 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 th em with cloth and wash it away with water.
• Before working, disconnect connect ors of ABS actuator and electric unit (control unit) or battery
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 the air from the brake hydraulic system. Refer to BR-9," Bleeding Brake System " .
Bleeding Brake System INFOID:0000000004305894
CAUTION:
• While bleeding, pay attention to master cylinder fluid level.
• Before working, disconnect connectors of ABS actuator and electri c 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.

6. Following the steps 1 to 5 above, with master cylinder reservoir tank filled at least half way, bleed air from
the rear right, front left, rear left, and front right brake, in that order.

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 Hose INFOID:0000000004305897
REMOVAL
1. Drain brake fluid. Refer to BR-9, " Drain and Refill " .

Inspection After Installation INFOID:0000000004305898
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.
1. Check brake hose, tube, and connections for fluid leak s, damage, twisting, deformation, contact with other
parts, and loose connections.
2. While depressing pedal under a force of 785 N (80 kg-f, 177 lb-f) with the engine running for approxi- mately 5 seconds, check for fluid leaks from each part of the brake hydraulic system. SFIA1120E

Inspection INFOID:0000000004305900
CAUTION:
• Carefully monitor brake flui d 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
