brake sensor FORD MUSTANG 2003 Workshop Manual

„
Frequencies have a range of plus or minus 2. A reading of 10 Hz can be displayed as an
8 Hz through 12 Hz.
d. Place the vibration sensor on or near the suspect area outside the vehicle.
e. Continue the road test, driving the vehicle at the speed the symptom occurs, and take another reading.
f. Compare the readings.
„A match in frequency indicates the problem component or area.
„ An unmatched test could indicate the concern is caused by the engine, torque converter,
or engine accessory. Use the EVA in the rpm mode and check if concern is rpm related.
„ Example: A vibration is felt in the seat. Place the sensor on the console. Record the
readings. Place the vibration sensor on the rear axle. Compare the readings. If the
frequencies are the same, the axle is the problem component.
Vibrate Software®
Vibrate Software® ( Rotunda tool number 215- 00003) is a diagnostic aid which will assist in pinpointing
the source of unacceptable vibrations. The engine's crankshaft is the point of reference for vibration
diagnosis. Every rotating component will have an angular velocity that is faster, slower, or the same as
the engine's crankshaft. Vibrate Software® calculates the angular velocity of each component and
graphically represents these velocities on a computer screen and on a printed vibration worksheet.
The following steps outline how Vibrate Software® helps diagnose a vibration concern:
zEnter the vehicle information. Vibrate will do all the calculations and display a graph showing
tire, driveshaft and engine vibrations.
z Print a Vibration Worksheet graph. The printed graph is to be used during the road test.
z Road test the vehicle at the speed where the vibration is most noticeable. Record the vibration
frequency (rpm) and the engine rpm on the worksheet graph. The point on the graph where the
vibration frequency (rpm) reading and the engine rpm reading intersect indicates the specific
component group causing the concern.
„An EVA or equivalent tool capable of measuring vibration frequency and engine rpm will
be needed.
z Provide pictures of diagnostic procedures to aid in testing components.
Combination EngineEAR/ChassisEAR
An electronic listening device used to quickly identify noise and the location under the chassis while
the vehicle is being road tested. The ChassisEARs can identify the noise and location of
damaged/worn wheel bearings, CV joints, brakes, springs, axle bearings or driveshaft carrier bearings.
EngineEAR Basic Unit
An electronic listening device used to detect even the faintest noises. The EngineEARs can detect the
noise of damaged/worn bearings in generators, water pumps, A/C compressors and power steering
pumps. They are also used to identify noisy lifters, exhaust manifold leaks, chipped gear teeth and for
detecting wind noise. The EngineEAR has a sensing tip, amplifier, and headphones. The directional
sensing tip is used to listen to the various components. Point the sensing tip at the suspect component
and adjust the volume with the amplifier. Placing the tip in direct contact with a component will reveal
structure-borne noise and vibrations, generated by or passing through, the component. Various
volume levels can reveal different sounds.
Ultrasonic Leak Detector
The Ultrasonic Leak Detector is used to detect wind noises caused by leaks and gaps in areas where
there is weather- stripping or other sealing material. It is also used to identify A/C leaks, vacuum leaks Klj . 12 ba

6. For vehicles with a two-
piece hub and brake disc assembly:
z Match-mark before disassembly.
z Remove the brake disc.
z Clean the hub and brake disc mounting surfaces with metal surface cleaner.
z Using a die grinder with a mild abrasive (Scotch Brite® type), remove any rust or
corrosion from the hub and brake disc mounting surfaces.
z Align the match- marks and reinstall the brake disc on the hub.
7. CAUTION: Do not use a bench lathe to machine brake discs.
NOTE: The depth of cut must be between 0.10 and 0.20 mm (0.004 and 0.008 inch). Lighter
cuts will cause heat and wear. Heavier cuts will cause poor brake disc surface finish.
Using an on- car brake lathe, machine the brake discs. Follow the manufacturer's instructions.
After machining, make sure the brake disc still meets the thickness specification.
8. Using the special tools, verify that the brake disc lateral runout is now within specification. For additional information, refer to Section 206 - 00 .
9. Remove the special tool hub adapter.
10. Remove any remaining metal chips from the machining operation.
11. For vehicles with a two- piece hub and brake disc assembly:
z Remove the brake disc from the hub.
z Remove any remaining metal chips from hub and brake disc mounting surfaces and from
the ABS sensor.
z Apply a liberal amount of lubricant to the hub flange, pilot area and to the brake disc- to-
hub mounting surface.
z Using the match marks, mount the brake disc on the hub.
12. Install the brake caliper anchor plate and the brake caliper.
13. Install the tire and wheel assembly.
14. Test the system for normal operation. Klj . 2 ba
