Installing

Note:
Before pressing the piston back, remove some
brake fluid from the reservoir. Use a bleeder
bottle or a plastic bottle which is only used for
brake fluid. Brake fluid is poisonous and must not
be siphoned by mouth through a hose. Note: - Thread in piston by turning knurled wheel of
special tool 3272 clockwise.
- Install brake pads. Install special tool 3272 so that the collar (arrow)
of the tool is seated against the brake caliper. If the piston is difficult to move, use a 13 mm
open end wrench on the flats (arrow A) provided
for this purpose. If the piston is pushed back with a piston resetting
tool or by operating the foot brake, the automatic
adjustment in the brake caliper will be destroyed. Page 8 of 10Rear wheel brakes, servicing (disc brakes)12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.46.5
