PARKING BRAKE LEVER STROKE CHECKM36FEAK
1. Pull the parking brake lever with a force of approx. 200 N d(45
Ibs.), and count the number of notches.
Caution
The 200 N
(45 Ibs.) force of the parking brake lever must
be strictly observed.Standard value: 3
- 5 notches
2.If the parking brake lever stroke is not the standard value,
adjust as described below.
(1) Remove the cup holder and plug and loosen the
adjustment nut to the cable end so that the cable
becomes free.
(2) Repeat depressing the brake pedal until the pedal
stroke becomes stable.
NOTEWhen the brake pedal is repeatedly depressed, shoe
clearance is adjusted properly.
(3) Disengage the drive shaft and companion flange.
(4) Remove the adjusting hole plug. Using a screwdriver,
turn the adjuster in the direction of the arrow (to expand
the shoe) until brake is lightly applied [where the disc
cannot be turned with both hands: approx. 2.7 Nm (23in.lbs.)]. Then, turn the adjuster five notches in the
direction opposite the arrow.
(Reference: Shoe clearance on one side 0.19 mm
‘d
I.0075 in.])
(6) After the parking brake lever stroke has been adjusted,
jack up the rear part of the vehicle. Loosen the parking
brake and turn the rear wheel to check that the parking
brake does not drag.
PARKING BRAKE SWITCH CHECKM36FDAG
1.Disconnect the connector of the parking brake switch, and
connect an ohmmeter to the parking brake switch and the
switch installation bolt.
2.The parking brake switch is good if there is continuity when
the parking brake lever is pulled and there is no continuity
when it is returned.
,(JTSB Revision
(51 Turn the adjusting nut to obtain specified parking brake
lever stroke. After the adjustment, check that there is
no play between the adjusting nut and pin.
