2. Measure distance between centers of brake lever
hole (G) and brake rod hole (I), distance should be
85 mm (3.35 in.).
3. If not, gradually adjust jam nuts (F and J) until
specified measurement is obtained.
4. Depress pedal (A) and lock park brake (B).
5. Measure distance between end of compression
spring bracket (C) and front edge of brake rod stop
tabs (D), gap should have a minimum distance of
2 mm (0.08 in.).
6. Check brake rod compression spring (E), it should
not be completely compressed, as shown, when
park brake is locked. A slight air gap should be
visible between the coils when proper adjustment is
reached.
7. Recycle park brake a few times and remeasure
distances each time until specified measurements
are obtained.
8. Brake lever travel (H) should not exceed 30°, if it
does measure brake components individually.
