1.Load sensing spring length check (Refer to  ).
|
|
2.Remove the bleeder from the front disk brake calliper and rear drum brake cylinder, and
connect a pressure gauge.
3.Air bleeding (Refer to ).
4.Unhook the spring support side.
|
|
5.
| caution |
The lever should be fully compressed toward the load sensing
proportioning valve side.
|
Pull the spring toward the "A" direction in parallel with the load sensing proportioning
valve. Adjust the length "H" as shown in the illustration to the specified dimension. At this time,
check that the front disc brake caliper output fluid pressure and rear drum brake cylinder output
fluid pressure are within the standard value.
Standard value:
|
|
Rear suspension
|
Length H mm
|
Front disc brake caliper output fluid pressure MPa
|
Rear drum brake cylinder output fluid pressure MPa
