Since the check valve is fit to the vacuum hose, replace thecheck valve as an assembly unit together with the vacuum
hose if the check valve is defective.
SERVICE POINTS OF INSTALLATIONNOWDAV
10. APPLICATION OF GREASE TO CLEVIS PIN/g. WASHERAfter applying the specified grease to the
clevis pin and
washer, insert the clevis pin and bend the cotter pin tightly.
Grease: MOPAR Multi-mileage Lubricant
Part No. 2525035 or equivalent
7. APPLICATION OF SEALANT TO
FITTINGWhen installing the vacuum hose fitting, apply semi-drying
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

SERVICE POINTS OF INSTALLATIONNO5LDAG
2. INSTALLATION OF FRONT BRAKE ASSEMBLY(1) Measure hub torque with pad removed to measure
brake drag torque after pad installation.
NOTETighten the nuts in order to secure the disc to the hub.
(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.
If the difference between brake drag torque and hub torque
exceeds the standard value, disassemble piston and cleanthe piston. Check for corrosion or worn piston seal.
Standard value: 70
N (15 Ibs.) or less[4 Nm (3
ft.lbs.)J or less

5. LOCK PIN BOOT/4. LOCK PIN SLEEVEApply the specified grease to the following points:
(1) Guide pin boot inner surface (lip)
(2) Lock pin boot inner surface (lip)
(3) Lock pin sleeve (not on threads)
Specified grease: Repair kit grease (orange)
After assembling the rear disc brake assembly, install to thebody, and then make the adjustment of the parking brake
lever as described below.
(1) Free the parking brake cable.
(2) With the engine running, firmly depress the brake pedalfive or six times.
(3) Check whether or not the stroke of the parking brake

servicing clutch assemblies or com-
ponents for vehicles with 1.8L engine, doNOT
create dust by sanding or by cleaning
clutch parts with a dry brush or with
compressed air. (A water dampened cloth
should be used). The clutch disc contains
“Asbestos Fibers” which can become air-
borne if dust is created during serviceoperations. Breathing dust containing
“Asbestos Fibers”may cause seriousbodily
harm.
