Play and clearance between brake pedal and floor panel with pedal depressed
1. Check brake pedal height from dash lower panel.
2. Adjust height referring to the following specifications.
ADJUSTMENT
1. Loosen stop lamp switch and ASCD cancel switch (or brake switch) by rotating it counterclockwise by 45 °.
2. Loosen lock nut (A) on input rod, then rotate input rod to set pedal to the specified height, and tighten lock nut (A). Refer to
BR-14, "
Component".
CAUTION:
Make sure the threaded end of input rod stays inside clevis.
3. With pedal pulled and held by hand, press stop lamp switch and ASCD cancel switch (or brake switch) until its threaded end con-
tacts stopper rubber.
4. With the threaded end of stop lamp switch and ASCD cancel switch (or brake switch) contacting stopper rubber, rotate switch
clockwise by 45 ° to secure.
CAUTION:
Make sure that the clearance “C” between stopper rubber
and threaded end of stop lamp switch and ASCD cancel
switch (or brake switch) is within the standard.
5. Check pedal play. CAUTION:
Make sure that stop lamps go off when pedal is released.
6. Start engine to check brake pedal depressed height.

BRAKE TUBE AND HOSE
BRAKE TUBE AND HOSE
Hydraulic CircuitINFOID:0000000001327613
CAUTION:
 All brake hoses and tubes 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.
 The brake tubes and hoses is an important safety pa rt. If a brake fluid leak is detected, always disas-
semble the parts. Replace applicable part with a new one, if necessary.
 Be careful not to splash brake fluid on painted areas; it way cause paint damage. If brake fluid is
splashed on painted surfaces of bo dy, immediately wipe it off and them wash it away with water
immediately.
 Do not bend or twist brake hose sharply, or strongly pull it.
 When removing components, cover br ake line connections so that no dirt, no dust, or other foreign
matter gets in.
 Refill with new brake fluid “ DOT 3 ”.
 Do not reuse drained brake fluid.
Removal and Installation of Fr ont Brake Tube and Brake HoseINFOID:0000000001327614
REMOVAL
1. Drain brake fluid. Refer to BR-8, "Drain and Refill".
2. Using a flare nut wrench, remove brake tube from brake hose.
3. Remove union bolt and remove brake hose from caliper assembly.
4. Remove lock plate and remove brake hose from vehicle.
INSTALLATION
1. Position brake hose by aligning with the protrusion on caliper assembly, and them tighten union bolt to the specified torque.
CAUTION:
Do not reuse copper washer.
2. Install brake hose to brake tube. Temporarily tighten flare nut by hand as much as possible. Secure them it to bracket with lock
plate.
3. Using a flare nut torque wrench, tighten flare nut to the specified
torque.
4. Refill brake fluid and bleed air. Refer to BR-8, "
Bleeding Brake
System".
