Cylinder Head InspectionS7RS0B1406027
• Remove all carbon deposits from combustion chambers.
NOTE
Do not use any sharp-edged tool to scrape
off carbon deposits. Be careful not to scuff or
nick metal surfaces when decarbonizing. The
same applies to valves and valve seats, too.

• Check cylinder head for cracks on intake and exhaust ports, combustion chambers, and head surface. Using
a straightedge and thickness gauge, check flatness of
gasketed surface at a total of 6 locations. If distortion
limit is exceeded, correct gasketed surface with a
surface plate and abrasive paper of about #400
(Waterproof silicon carbide abrasive paper): place
abrasive paper on and over surface plate, and rub
gasketed surface against paper to grind off high spots.
Should this fail to reduce thickness gauge readings to
within limit, replace cylinder head.
Leakage of combustion gases from this gasketed joint
is often due to warped gasketed surface: such
leakage results in reduced power output.
Distortion for cylinder head surface on piston side
Limit: 0.03 mm (0.001 in.) • Distortion of manifold seating faces:
Check seating faces of cylinder head for manifolds,
using a straightedge and thickness gauge, in order to
determine whether these faces should be corrected or
cylinder head replaced.
Distortion for cylinder head surface on intake and
exhaust manifold
Limit: 0.05 mm (0.002 in.)

Rear Brake Hose / Pipe ConstructionS7RS0B4101003
Diagnostic Information and Procedures
Brakes Diagnosis NoteS7RS0B4104001
Road Testing Brakes
Brakes should be tested on dry, clean, smooth and
reasonably level roadway which is not crowned. Road
test brakes by making brake applications with both light
and heavy pedal forces at vari ous speeds to determine if
the vehicle stops evenly and effectively. Also drive
vehicle to see if it leads to one side or the other without
brake application. If it does, check the tire pressure, front
wheel alignment and front suspension attachments for
looseness. See diagnosis table for other causes. Brake Fluid Leaks
Check the master cylinder fl
uid levels. While a slight
drop in reservoir level does result from normal lining
wear, an abnormally low leve l indicates a leak in the
system. In such a case, chec k the entire brake system
for leakage. If even a slight ev idence of leakage is noted,
the cause should be corrected or defective parts should
be replaced.
Substandard or Contaminated Brake Fluid
Improper brake fluid, mineral oil or water in the fluid may
cause the brake fluid to boil or the rubber components in
the hydraulic system to deteriorate.
