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

- Secure brake caliper housing with new self-
locking bolts. Note: - Attach parking brake cable (arrow) to brake caliper housing. After each brake pad change firmly depress brake
pedal several times with vehicle stationary, so
that the brake pads are properly seated in their
normal operating position. After changing brake pads check brake fluid level. Page 9 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

Parking brake, adjusting (disc brakes)

Note:
Due to the self-adjusting rear brakes there is no
requirement to adjust the parking brake.
Adjustment is only necessary after replacing
parking brake cables, brake calipers, brake
pads and brake discs. Remove hand grip and central console to allow
access to adjusting nuts (arrows) Page 46-39 . - Parking brake lever in "off" position. Tighten
adjusting nut until lever (arrow) lifts off the brake
caliper stop.
- A gap of max. 1.5 mm from stop (arrow) is
permissible each side but should be set the same
on both sides.
- Pull parking brake on and then release again. - Check that both wheels turn freely. Page 10 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
