NOSFNAJ
When checking the check valve, keep the check valve fit in thevacuum hose.
1. Remove the vacuum hose.
Caution
The check valve is press-fit inside the vacuum hose and
do not remove the check valve from the vacuum hose.
2.Check the operation of the check valve by using a vacuum
pump.Vacuum pump connection Accept/reject criteria

Caution
If the check valve is defective, replace it as an assembly
unit together with the vacuum hose.PROPORTIONING VALVE FUNCTION TEST
NOSFKAJ
1.Connect two pressure gauges, one each to the input side
and output side of the proportioning valve, as shown.
2. Air bleed the brake line and the pressure gauge.
3. While gradually depressing the brake pedal, make the
following measurements and check to be sure that the
measured values are within the allowable range.
(1) Output pressure begins to drop relative to input
pressure (split point).
Standard value:3.95-4.45
MPa (561-633 psi)3.45-3.95
MPa (491-561 psi)
(2) Output fluid pressure when input fluid pressure are as
follows.
Standard value:
tFVVD>5.15-5.65 MPa (732-804 psi)
[at 8.2
MPa (1,163 psi)]4.65-5.15
MPa (661-732 psi)
[at 7.7
MPa (1,095 psi)],
(3) Output pressure difference between left and right
brake lines
Limit: 0.4
MPa (57 psi)
4. If the measured pressures are not within the
permissibleranges, replace the proportioning valve.

REAR BRAKE DISC RUN-OUT CHECKNOSWAB
1.Remove the caliper support, raise the caliper assembly, and Ir.secure it by using a wire, etc.
-u/2. Place a dial gauge approximately 5 mm
(2 in.) from the
outer circumference of the brake disc, and measure the
run-out of the disc.
Limit: 0.08 mm
(.0031 in.)
NOTETo secure the disc to the hub, tighten the nuts.
REAR BRAKE DISC RUN-OUT CORRECTIONNWFXAA
1.If the run-out of the brake disc is equivalent to or exceeds
the limit specification, change the phase of the disc and
hub, and then measure the run-out again.
rc
NOTEThe procedures for checking by changing the installation
phase of the disc are the same as those for the front brakediscs. (Refer to
P.5-48.)
2.If the problem cannot be corrected by changing the phase
of the brake disc, replace the disc.

sealant to its threaded portion.
6. INSTALLATION OF VACUUM HOSE WITH CHECK
VALVE(1) Attach the vacuum hose so that it may be inserted to a
dimension illustrated.
Caution
Prevent interference between the check valve and
brake booster.(2) The vacuum hose at the engine should be securely
connected until it contacts the hexagonal edge of the
fitting, and then should be secured by the hose clip.

(2) After installing the caliper support to the knuckle,
expand the piston, and then install the caliper body.
1. INSTALLATION OF BRAKE HOSEInstall brake hose without twisting or kinking.
Check brake drag torque as follows.
(1) Start engine and hold brake pedal down for 5 seconds.
(2) Stop engine.
(3) Turn brake disc forward 10 times.
(4) Check brake drag torque with spring scale.
