– Smear the brake discs with transmission oil. – Refit the discs. N.B.: Check that the disc slides freely on the planetary.
5
– Carry out the tightness test.
A
B
– Refit the axle tubes (Refer to section: "02 40"). – Fill the circuit with "LHM" liquid. – Drain the main brake circuit. – If mounted: Drain the trailer brake circuit. – Check the seals on the dismantled elements.
C
– Perform road braking tests.
D
Sealing test Important: When intervening on the brake piston and O-rings, it is highly recommended to check the sealing.

– Adapt a pneumatic inflating piece (C) onto a DIN (A) fitting. – Screw the assembly onto the elbow (5). – Connect up a conventional inflation valve with its pressure gauge. – Fit the pressure regulator nr.60 0500 531 0 upstream. – Connect to a conventional inflation handle fitted with its pressure gauge and place a presssure release valve n° 60 05 005 310 upstream. – Supply the circuit with 5-bar compressed air to ensure the proper operation of the piston. – Reduce the pressure to 0,3 bar. – Close the pressure regulator valve. After 1 minute, no pressure drop should be observed at the pressure gauge.
