TRANSMISSION PARKING BRAKE

 

 

The parking brake is mounted on the transmission gearbox and can be 
accessed from the underside of the dumper. Wear can occur either by 
stretching of the handbrake cable, or wear on the disc pads themselves, 
causing a reduction in efficiency. Brake pads generate dust which if 
inhaled, may endanger health. Wash off the calliper assembly before 
commencing work. Clean hands thoroughly after work. 

 

ADJUSTING THE PARKING BRAKE

 

 
 

TAKE UP THE CABLE SLACK 

• 

Disengage the parking brake (A) (lever horizontal) 
and turn the handle grip clockwise half a turn. 

• 

Test the parking brake. 

• 

If the brake fails the test, repeat the procedure. 

 

CHECK THE PADS

 

• 

Use feeler gauges to check the gap between the brake 
disc (B) and the face of the brake calliper housing 
(C). 

• 

The gap should be greater than 1mm (0.04 in). If gap 
is less than 1mm renew the pads. 

 

RENEW THE BRAKE PADS 

• 

Disengage the parking brake (A) (lever horizontal). 

• 

Slacken the nuts (D) and unhook the clevis (E). 

• 

Loosen and remove bolts (F) and remove the calliper 
assembly. 

• 

Remove the old brake pads from the calliper 
assembly and fit the new pads. Align the flat across 
the top of the pads with the calliper housing. 

• 

Refit the calliper assembly to the gearbox, torque 
bolts (F) to 244Nm (180lbf ft). 

• 

Refit clevis (E). 

• 

Adjust the cables effective length so that the park 
brake is fully engaged with the lever (A) vertical. 

• 

Adjust at (D) and or at the clevis (E) & tighten nuts. 

• 

If more adjustment is required this can be done at the 
park brake mounting position. 

• 

In the event of insufficient adjustment remove screw 
(G), the anti-rotation clip and adjust the lever (H) on 
the spline. Rotate the lever by one spline and refit the 
assembly. Torque the screw to 12.5Nm - 15.5Nm (9.2 
- 11.5lbf ft). 

• 

Test the parking brake.
