CV joint boots
NOTE-
When replacing a CVjoint boot, use a complete CVjoint
boot repair kit. The lit will include a new boot, clamping
bands, special lubricant, and a new inner CV joint circlip.
The lit is available from an authorized
BMW dealerparts
department.
The outer CVjoint cannot be removed from the axle
shaft
In order to replace the outer CV boot, it is necessary to re-
move the inner joint and boot first.
If the
CVjoints are worn or defective, a complete rebuilt
axle shaft is available from an authorized
BMW dealer
parts department.
- Remove appropriate axle shaft. See Drive axle, removing
and installing (sedan), or Drive axle, removing and in-
stalling (Sport Wagon).
- Working with axle shaft at bench, cut off old boot clamps and
remove boot. Clean old grease off joint and shaft. Use new
grease from CV joint boot kit.
4 Remove dust cover from CV joint and remove circlip (arrow)
retaining joint inner hub to axle shaft.

4 Support inner hub with BMW special tools 26 1 110 and
press axle shaft out of joint using BMW special tool 21 2 120.
- Clean all old lubricant off shaft splines and inner joint splines.
If the CVjoint must be disassembled for cleaning and inspec-
tion, be sure to matchmark inner and outer race and interme-
diate ball cage. This allows reassembly
ofparfs in their
original positions.
NOTE-
To inspect a CVjoint, clean away the grease and loolc forgall-
ing, pitting, and other signs of wear orphysical damage. Pol-
ishedsurfaces or visible ball traclts alone are not necessarily
cause forreplacement. Discoloration due to overheating indi-
cates
laclt of lubrication.
- Slide CV joint boot onto axle shaft
- Apply LoctiteO270 or an equivalent heavy-duty loclting corn-
pound to drive axle splines. Position new CV joint on shaft so
that raised or taller side of hub is facing shaft.
WARNING-
Do not let the locking compound contact the balls in the joint.
Apply only a thin coat to cover the splines.
While supporting axle shaft with BMW special tool
33 2 130
press inner hub of CV joint onto shaft. Install a new circlip.
- Install new boot clamps.
- Use sealing gel to seal dust cover to CV joint prior to reinstal-
lation.
NOTE-
* Do not let the ball hub pivot too far in the outer ring of the
joint.
Tlie balls will fa1 out.
Before installing each small boot clamp be sure to
'burp"the
boot by flexing the CVjoint. A small screwdriver inserted be-
tween the boot and the axle shafl will help the process.

4 Apply a thin coating of BMW anti-squeal compound to caliper
contact face
(arrow).
Do not apply grease to brake pad backing plate.
Right Left
CAUTION-
Do not let calliper rubber dust sleeve come in contact with
anti-squeal compound. The rubber will swell and deteriorate.
4 Apply a thin coating of BMW anti-squeal compound to bralte
pad rests (arrows) on pad carrier.
4 When installing directional brake pads, install the marked
pads as shown.
NOTE-
BMW-supplied (OEM) front brake pads may be marked as di-
rectionalpads. Aftermarket brands are generally not labeled
as directional. When installing directional pads, be sure to in-
stall them as indicated in the illustration.
- Where applicable, insert brake pad wear sensor into cutout
in new pad. Push sensor into pad cutout until it locks into
place.

- NOTE-
If brake lining indicator light illuminatedprior to brake pad re-
placement, replace wear sensor.
- Route pad wear sensor wiring through caliper opening and
under bleeder dust cap.

- Remainder of installation is reverse of removal.
- Clean brake caliper mounting bolts (7 mm Allen). Replace
ones which are not in perfect condition. Do not grease.
Top up brake fluid to MAX marking.
- Before driving car, pump bralte pedal several times so that
brake pads contact brake rotors.
Check that brake fluid level is correct. Top up if necessary.
Hold ignition key for at least
30 seconds in accessory po-
sition without starting engine. This clears any fault codes in
memory and turns off brake pad warning light.

caliper from chassis using stiff wire.
NOTE-
Hydraulic brake line remains connected.
4 Remove bralte rotor mounting screw (arrow) and remove ro-
tor.
- Inspect rotor for cracks, signs of overheating and scoring.
- Minimum allowable thickness (MIN TH) is stamped on rotor
hub. Measure rotor braking surface with a micrometer at
eight to ten different points and use the smallest measure-
ment. Compare to specifications in table below.
- If rotor does not pass minimum thickness requirements or is
damaged, replace rotor.

4 Disconnect bralte fluid level sensor connector (A) from fluid
reservoir. Remove reservoir cap.
. Using a clean syringe, empty bralte fluid reservoir.
Where applicable, disconnect hydraulic clutch system sup-
ply line from fluid reservoir duct
(5). Keep supply line sup-
ported and above clutch master cylinder to prevent air
bubbles from reaching clutch hydraulic system.
Where applicable, disconnect DSC system precharge
pump supply line from fluid reservoir duct
(C). Secure sup-
ply line in vertical position to prevent fluid loss.
Plug open brake fluid lines and ducts to prevent fluid leak-
age or contamination.
