1. 4.1. Before fitting the brake pads listed below , grease the piston contact surface -arrows- on the backing plate using Interflon HT.

2. 4.2. Brake pads with a large sliding plate -1- on the brake-pad backing plate (Part Nos. 997.351.938.05 and 997.351.938.06) must not be greased (status as at 01.04.2009).
  Reason: These brake pads (with a large sliding plate on the backing plate) have grease pockets between the brake-pad backing plate and the large sliding plate -1- .
  
  As a result, it is no longer necessary to grease the contact surface on the brake pistons with Interflon HT.
