BRAKE BOOSTER

INSPECTION AFTER REMOVAL
Output rod length inspection
1. Using a handy vacuum pump, apply a vacuum of -66.7 kPa (-500 mmHg, -19.69 inHg) to the brake
booster.
2. Check output rod length.
3.
INSTALLATION
1. Loosen lock nut to adjust input rod length so that length “B” (in
the figure) satisfies the specified value.
2. After adjusting “B”, temporarily tighten lock nut to install booster
assembly to vehicle.
3. Connect brake pedal to input rod clevis.
4. Connect brake pedal assembly mounting nuts and tighten to the
specified torque.
5. Connect master cylinder to booster assembly.
6. Adjust brake pedal height and play.
7. Tighten input rod lock nut to the specified torque.
8. Bleed air. Refer to BR-9, "
Bleeding Brake System" . Reference value at vacuum of –66.7 kPa (–500 mmHg,
–19.69 inHg):
Without ESP models : 10.4 mm (0.409 in)
With ESP models : -6.2 mm (-0.244 in)
SBR208E
Length “B” standard : 125 mm (4.92 in)

28. Install boot clamp.
a. Tighten large-diameter side of RH/LH boot with boot clamp
(stainless wire).
b. Wrap clamp around boot groove for two turns. Insert screwdriv-
ers in loops on both ends of wire. Twist 4 to 4.5 turns while pull-
ing them with force of approx. 98 N (10 kg, 22.1 lb).
c. Twist boot clamp as shown. Pay attention to relationship
between winding and twisting directions.
d. Twisted point should face front of vehicle with gear installed on
vehicle (to prevent interference with other parts).
e. After twisting wire 4 to 4.5 turns, bend cut end of wire. Cut end of
wire should not touch boot. Be sure wire end is at least 5 mm
(0.20 in) away from clearance for tube.
29. Connect lock nut and outer socket to inner socket. Temporarily
tighten lock nut until length of tie rod is within specification.
CAUTION:
Perform toe-in adjustment after this procedure. Length
achieved after toe-in adjustment is not necessarily value
given here.Wire length ( ): 370 mm (14.57 in)

InspectionEKS0031L
MAGNETIC SWITCH CHECK

Before starting to check, disconnect the battery cable from the negative terminal.

Disconnect “M” terminal of starter motor.
1. Continuity test (between “S” terminal and switch body).

No continuity... Replace.
2. Continuity test (between “S” terminal and “M” terminal).

No continuity... Replace.
PINION/CLUTCH CHECK
1. Inspect pinion teeth.

Replace pinion if teeth are worn or damaged. (Also check
condition of ring gear teeth.)
2. Inspect reduction gear teeth (If equipped).

Replace reduction gear if teeth are worn or damaged. (Also
check condition of armature shaft gear teeth.)
3. Check to see if pinion locks in one direction and rotates
smoothly in the opposite direction.

If it locks or rotates in both directions, or unusual resistance is
evident.... Replace.
BRUSH CHECK
Brush
Check wear of brush.

Excessive wear... Replace.

5. Check depth of insulating mold from commutator surface.

Less than 0.2 mm (0.008 in)... Undercut to 0.5 to 0.8 mm
(0.020 to 0.031 in).
AssemblyEKS0031M
Apply high-temperature grease to lubricate the bearing, gears and frictional surface when assembling the
starter.
Carefully observe the following instructions.
PINION PROTRUSION LENGTH ADJUSTMENT
Clearance (QR engine models)
With pinion driven out by magnetic switch, push pinion back to
remove slack and measure clearance “L” between the front edge of
the pinion and the pinion stopper.

Not in the specified value... Adjust by adjusting plate.
