OPERATION: REMOVING AND REPLACING LINES AND TUBINGS

 

When overhauling the hydraulic braking system, the removing and replacing of tubings and lines is done to enable their replacement or repair. This operation is done when these parts are in bad shape or they obstruct the removal of another part, for example, the suspension system of the vehicle.

METHOD OF EXECUTION:

1st step -

 Place the vehicle on the pit or lift (or hoist) and wedge the wheels if necessary.

 

NOTE:

Use a mirror in front the pit to enable the guiding of the wheels into their positions

 

SAFETY MEASURE:

MOVE THE VEHICLE SLOWLY SO AS TO PREVENT THE VEHICLE FROM FALLING INTO THE PIT.

2nd step - 

Remove the lines and tubings from the hydraulic system, thus:-

a)   Disconnect the fixtures of the lines, using a back-up spanner and another spanner to turn.

 

SAFETY MEASURE:

AVOID THE SPILLAGE OF BRAKE FLUID INTO YOUR EYES.

b)   Remove the retaining clips from the lines with the aid  of a pliers or suitable tool and a hammer.

c)    Remove the clamps that secure the tubings.

3rd Step - 

Clean and blow, inside and outside tubings and tines using alcohol-based fluid and compressed air.

 

SAFETY MEASURE:

DO NOT ALLOW THE CLEANING LIQUID TO COME IN CONTACT WITH THE SKIN.

 

4th Step - 

Replace the tubings and lines of the hydraulic systems thus:-

a) Install the lines into the vehicle, securing them with their retaining clips.

b) Connect the lines or tubings to the wheel cylinders.

c) Connect the tubings to the lines, using a spanner and a back-up spanner.
