BRAKE LININGS

OEFILIS assists installers with improved technical information when it comes to installation of brake linings, specifi cally for the applications listed above. OEFILIS has developed this specifi c installation guide to help customers to always correctly fi t brake linings to the shoes.

Iveco released a commercial report (No. 1209/I) dated 1996 about irregular wear cases (known as sickle) of some rear brake linings. In order to avoid this problem, Iveco provided a solution of a brake drum having a 15° pressure plate for the primary shoes. This means that currently there are two di erent sets of linings depending on the brake drum version. 


RECAP OF OLD VERSION (UP TO APRIL 1996) 

The brake linings of the primary shoe have two blind holes on the bearing side to mount the wear sensors; the other brake linings remained unchanged. 



NEW VERSION (FROM MAY 1996)

To ensure a uniform wear of the brake lining at the secondary and primary brake shoes, the supporting angle of the primary shoe has been changed (now 15°, marked on the web). The results are two di erent brake shoes and three di erent brake linings per brake. 

Reference K19716.0 (correspondent to the old ref K19553.0) is composed by 4 identical linings WVA 19553, these have to be fi tted on the secondary shoe. Other 2 linings, identifi ed with marking “P1” have to be fi tted on the primary shoes, anchor side. The last 2 linings, identifi ed with marking “P2” must be fi tted on the primary shoes wedge side. 

Similar situation for reference K19714.0 (correspondent to the old ref K19555.0). It is composed by 4 identical linings WVA 19556, these have to be fi tted on the secondary shoe. Other 2 linings, identifi ed with marking “P1” have to be fi tted on the primary shoes, anchor side. The last 2 linings, identifi ed with marking “P2” must be fi tted on the primary shoes wedge side. 

The markings “P1” and “P2” are engraved on the web of the primary shoe of the modifi ed brake, in correspondence of the lining position.
