Wheel brake caliper Electronic control module Fig. Schematic representation of ABS. SUSPENSION, STEERING ANDBRAKES-GENERAL 300-3 Fig. Schematic view ofdual circuit brakes with 4-channel ABS. Ing adverse conditions. It automatically adjusts brake system hydraulic pressure at each wheel to prevent wheel lock-up. The system's main components arethe wheel speed (pulse) sensors, the ABS control module, and the hydraulic control unit.
Warning lamp u Master Whee l speed I-lydraulic cylinder sensor control unit 0012135 UNI The wheel speed sensors continuously send wheel speed signals to the control module. The control module compares these signals to determine, in fractions of a second, whether any of the wheels areabout to lock. If any wheel is nearing a lock-up condition, the module signals the hydraulic unit to maintain or reduce pressure at the appropriatewheel(s). Pressure is modulated by electrically-operated sole- noid valves in the hydraulic unit. ABS wheelspeed sensor. 0006563 INTEGRATED SYSTEMS.

310-2 FRONT SUSPENSION WARNING- ' Physical safety could be impaired if procedures described here areundertaken without the proper service tools and equipment. Be sure to have the right tools onhand before beginning any job. ' Do notreuse self-locking nuts or bolts. They are designed to beused only once and may fail if re- used.
Always replace self-locking fasteners any timethey are loosenedor removed. ' Do not install bolts and nuts coated with under- coating wax, as the correct tightening torque can- not beassured. Always clean the threads with solventbefore installation, or install new parts. ' Do not attempt to weld or straighten any suspen- sion components. Replace damaged parts.
SHOCK ABSORBERS AND SPRINGS The complete front strut assembly is shown in Fig. Most strut assembly components are available asreplacement parts. NOTE- Struts andlor springs shouldalways be replaced in parts. Strut assembly, removing and installing 1.
Raisecar and remove front wheel. WARNING- Make sure that the car is firmly supported on jack standsdesigned for the purpose.
Place the jack standsbeneath a structural chassis point Do not place jack stands under suspension parts. Unbolt brake caliper assembly, keepingbrake hose connected. Detach brake hose from strut assembly. Suspend brake caliper from chassis using stiff wire.
Re- move brake rotor. See 340 Brakes. SHOCKABSORBERS AND SPRINGS 0011191 Fig. Front strut assembly with steering arm, front hub, front spring and strut upper mount. Remove ABS wheelspeed sensor.
Disconnect ABS sensor wire harness and brake pad wear sensor wire harness (left side only) from strut housing. OnM3 modeis: Disconnect stabilizer bar link from strut.
