If the brake disc displays signs of out-of-true, check its lateral run out. See Brake disc front, calibrating See: Brake Rotor/Disc Testing and Inspection Brake Disc Front, Calibrating.
Replace the brake disc if it displays signs of heavy wear, variable thickness or similar. To replace, see Brake disc front, replacing See: Brake Rotor/Disc Service and Repair Removal and Replacement Brake Disc Front, Replacing.

Brake discs with an outer diameter of 336mm = 27.0mm. Minimum recommended disc thickness when installing new brake pads = 27.8mm.
Note! For tightening torques, see Specifications See: Specifications Tightening Torque.
Lubricating the sliding surfaces
Lubricate the contact surfaces of the brake pads using silicone grease, part no. 1161687 (12 ml) or part no. 1161688 (50 ml)
(Do not lubricate the sliding pins)
Installing the brake pads

Insert the locating pins in the rubber sleeves.
Tighten the locating pins. Tighten. See: Tightening torque See: Specifications Tightening Torque.
Install the protective caps.
Install the securing spring.
