Brake System
General EquipmentPressure/vacuum gauge set
The Ford approved diagnostic tool
The brake system operates by transferring effort
applied to the brake pedal by the driver to the
brakes at each wheel.
The braking effort is distributed to each wheel,
using a hydraulic system. The system is assisted
using a vacuum brake booster that reduces pedal
effort and increases hydraulic pressure.
The parking brake operates on the rear wheels
and is applied using a hand operated control.
Inspection and Verification
NOTE: Before carrying out any diagnosis, make
sure that the brake system warning indicator is
functional.
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.
Visual Inspection Chart
Electrical
Mechanical
• Electricalconnector(s)
• Wiring harness(s)
• Switch(es)
• Tire pressure(s)
• Wheels and tires
• Fluid leak(s)
3. If an obvious cause for an observed or reported concern is found, correct the case (if possible)
before proceeding to the next step.
4. If the cause if not visually evident, verify the symptom and refer to the Symptom Chart.
Road Test
Carry out a road test to compare actual vehicle
braking performance with the performance
standards expected by the driver. The ability of the
test driver to make valid comparisons and detect
performance deficiencies will depend on
experience.
The driver should have a thorough knowledge of
the brake system operation and accepted general performance guidelines to make good comparisons
and detect performance concerns.
An experienced technician will always establish a
route that will be used for all brake diagnosis road
tests. The road selected will be reasonably smooth
and level. Gravel or bumpy roads are not suitable
because the surface does not allow the tires to grip
the road equally. Crowned roads should be avoided
because of the large amount of weight shifted to
the low set of wheels on this type of road. Once
the route is established and consistently used, the
road surface variable can be eliminated from the
test results.
Before a road test, get a complete description of
the customer concerns or suspected condition.
From the description, the technician will be able to
match possible causes with symptoms. Certain
components will be identified as possible sources
while others will be eliminated by the evidence.
More importantly, the customer description can
reveal unsafe conditions which should be checked
or corrected before a road test. The description will
also help form the basic approach to the road test
by narrowing the concern to specific components,
vehicle speed or conditions.
Begin the road test with a general brake
performance check. Using the description of the
concern, test the brakes at different vehicle speeds
using both light and heavy pedal pressure.
Determine if the concern is in the front or rear
braking system. First use the foot brake and then
the parking brake. If the condition (i.e. pull,
vibration, pulsation) occurs only on operation of
the parking brake, the concern is in the rear brake
system. If the condition occurs when the foot brake
is depressed, the concern is in the front brake
system.
Avoid locking the brakes and sliding the tires. This
condition will not indicate brake efficiency. A heavily
braked but turning wheel will stop the vehicle in a
shorter distance than locked wheels.
If the concern becomes evident during this check,
make sure it fits the description given before the
road test. If the concern is not evident, attempt to
duplicate the condition using the information from
the description.
If a concern exists, use the Brake System Symptom
Chart in order to isolate it to a specific sub-system
and condition description. From this description, a
list of possible sources can be used to further

• Faulty positive crankcase vent-
ilation (PCV) system.
- Hoses or ventilation orbreather valves are blocked.
This causes excessive
pressure in the crankcase
which causes more oil to
enter the combustion
chamber.
- PCV oil separator is faulty and engine oil can enter the
combustion chamber
through the intake manifold.
• INSTALL a new turbocharger.Engine - 2.5L Duratec-ST (VI5)

• Turbocharger seals.
• CHECK the gaskets and matingsurfaces for damage.
Remove the cylinder head.
CHECK the mating faces, cylinder

between the valve stem and
the valve stem guide.
• INSTALL new components asnecessary.
• Piston ring or cylinder liner
wear.
• CHECK the running surfacesand clearances of the individual
engine components. INSTALL
new components as necessary.
INSTALL a new cylinder block
if necessary.
• Check the pistons and piston rings.
• Damaged cylinder liners or
excessive clearance of engine
components.
- Pistons.
- Piston rings (clearance ingroove and end gap).

The front engine cover must always be fitted when
checking and adjusting the valve timing or timing
belt tension, as the timing marks for both camshaft
pulleys are provided on its front end.
Correct timing belt tension is ensured by the
automatic timing belt tensioner.
No direction of movement is specified when using
a new timing belt. If, however, the old timing belt
is reused, the direction of movement must be
marked prior to removal.
Once the timing belt has been correctly tensioned,
the engine must be rotated by hand two turns
clockwise at the crankshaft in order to allow a subsequent check of the timing belt tension and
adjustment.
Cylinder block
The cylinder block consists of three parts. These
are the cylinder block, the lower crankcase and the
sump pan. The cylinder block has five cylinder
liners made of cast iron, which cannot be replaced.
The pistons are made of a homogeneous aluminum
alloy with a graphite coating on the sides. This
coating serves to reduce friction and dampen noise.
The pistons are cooled from below via oil-spray
nozzles screwed into the cylinder block.
