ADJUSTMENT
1. Loosen the stop lamp switch and by turning it counterclockwise
by 45°.
2. Loosen lock nut (A) on the input rod, then turn input rod to adjust
the pedal to specified height, and tighten lock nut (A).
CAUTION:
Make sure the threaded end of the input rod stays inside the
clevis.
3. With the pedal pulled and held by hand, press the stop lamp
switch and until its threaded end contacts the stopper.
4. With the threaded end of the stop lamp switch and contacting
the stopper, turn the switch clockwise by 45°to secure.
CAUTION:
Make sure that the clearance (C) between the bracket and
threaded end of the stop lamp switch and are within the
standard.
5. Check the pedal play.
CAUTION:
Make sure that the stop lamp goes off when the pedal is
released.
6. Start the engine to check the brake pedal depressed height.

CAUTION:
lAll brake tubes and hoses must be free from excessive bending, twisting and pulling.
lMake sure that there is no interference with other parts when turning steering both clockwise and
counterclockwise.
lBrake tube and hose is 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.
lBe 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 off them and wash it away with water.
lDo not bend or twist brake hose sharply, or strongly pull it.
lCover the open end of brake tube and hoses when disconnecting to prevent entrance of dirt.
lRefill with new brake fluid “DOT 3” or “DOT 4”.
lNever reuse drained brake fluid.

FRONT DISC BRAKE
ASSEMBLY
CAUTION:
When assembling, use only rubber lubricant specified below.
1. Apply polyglycol ether based lubricant to the piston seal, and
install them to the cylinder body.
2. Apply brake fluid to piston and apply rubber grease to piston
boot.Coverthepistonendwiththepistonboot,andtheninstall
cylinder side lip of the piston boot securely into the groove on
cylinder body.
3. Insert piston into cylinder body by hand and insert piston boot
piston-side lip into the piston groove.
CAUTION:
Press the piston evenly and vary the pressing point to pre-
vent cylinder inner wall from being rubbed.
4. Install sliding pin and sliding pin boot to torque member.
5. If pad assemblies are removed, install pad assemblies to torque member. Refer toBR-25, "
Removal and
Installation of Brake Pad".
6. Install cylinder body to torque member, and then tighten sliding pin bolt to the specified torque. Refer to
BR-24, "
Components".
DISC ROTOR INSPECTION
Visual Inspection
Check surface of disc rotor for uneven wear, cracks, and serious damage. If any of them is detected, replace
applicable part.
Runout Inspection
1. Using wheel nuts, secure disc rotor to wheel hub. (2 or more positions)
2. Check runout using a dial indicator.
[measured at 10 mm (0.39 in) inside the disc edge]
CAUTION:
Make sure that wheel bearing axial end play is within the
specifications before measuring runout. Refer toFAX-5,
"WHEEL BEARING INSPECTION".
3. If runout is outside the limit, find the minimum runout point by
shifting mounting positions of disc rotor and wheel hub by one
hole.
4. If runout is still out of the specification, refinish the disc rotor with
on-car brake lathe (“MAD, DL-8700”, “AMMCO 700 and 705” or equivalent). Or replace the disc rotor.
