MAINTENANCE
PROCEDURES 10-7
Road wheels
Remove
1.Mark the wheel to stud relationship to ensure
that the wheels are refitted in the same
position.
2.Loosen wheel nuts. Raise the vehicle to a
wheel-free condition and remove the wheel
nuts.
Tyres
Check
1.Check tyres for compliance with manufacturer's
specification; visually for cuts, lumps, bulges,
uneven tread wear and depth.
2.Check tyre pressures, condition and tread
depth. Measure the tread depth across the
width of the tyre and around the circumference.
Brake pads, discs and calipers
Check
1. Check front and rear brake pads for wear,
ensure all pads are wearing evenly.
2.Check brake discs for signs of cracking,
excessive scoring or oil contamination.
3.Check calipers for signs of fluid leaks.
4.Clean excessive deposits of brake dust from
pads, calipers and disc shields using brake
cleaner.
Road wheel speed sensors
Inspect
Front wheel
Rear wheel
1.Inspect each sensor harness for damage.
