pump,  DSC without precharge  pump). Be sure to use correct 
specification  brake fluid, according  to application  table below. 
Brake  fluid applications 
ABS I ASC and ABS / DSC models DOT 4 brake fluid 
with precharge  pump (to 911998) 
ABS I DSC models without  precharge DOT 4 low viscosity 
pump  (911998  and later)  brake

- Open bleeder screw.  Carry out bleeding  procedure  with 
BMW  Service  Tester until clear, bubble-free fluid  flows. 
Models  with DSC:  After  BMW  Service Tester bleeding rou- 
tine  has finished,  press brake  pedal to floor 
5 times  until 
clear, bubble-free fluid  runs out.  Close right rear bleeder 
valve.

Brakes Brake pads, checking and replacing 
Brake pads can be replaced without disconnecting the brake 
fluid hose from the caliper  or having  to bleed the brakes. The 
rotors can  be replaced without disassembling  wheel hub and 
bearing.  Always machine  or replace  rotors in pairs.  Replace 
pads in sets. 
Front  and rear brake pad  replacement procedures  are identical.

NOTE- 
If  there  is a ridge  on brake rotor  edge, press  caliper pistons 
back  into caliper before removing  caliper. 
- Check brake rotor thickness. Inspect  for rust  or damage.  if 
necessary replace  or machine brake  rotors as described  lat- 
er.  Bralte  rotor specifications are  given in table  below....
