Mechanical Braking System Flashcards
What does the braking system provide the operator with?
A means of slowing down and stopping the ASE
The ability to prevent ASE movement when parking
What is the braking system controlled by?
Foot pedal or hand lever
What is the foot pedal and hand lever designed to do?
Give leverage that creates a mechanical advantage to which reduces driver effort
What do the adjustable rods do?
Link the cross shaft to the brake operating levers
Why is adjustment required with the rods?
To help achieve balanced braking
What do the elongated holes allow?
Independent movement of each control
What does the cross shaft do?
Balances the application of the brakes to all four wheels
What do wrongly adjusted rods do?
Cause ASE to pull to the left or right
What are placed to take up any unequal adjustment?
Compensators
What do fully compensated braking systems ensure?
Each brake is applied at the same time
Each brake receives its equal share of braking effort
Where are the 3 common compensator locations?
Front (balance front brakes)
Rear (to balance rear brakes)
Centre (to equalise front and rear)
What does the back plate do?
Attaches to the axle and provides a base for mounting other brake components
Acts as a seal to stop ingress of dirt and water
How is the brake shoe anchor attached?
Bolted or riveted
What does the brake shoe anchor do?
Prevents the shoes rotating in the drum
Provides leverage for shoes to act against
What does the integral adjuster do?
Adjust the shoe drum clearance
