Downhill gradients !
On
long, steep gradient s,you must reduce
the load onthe brakes. Touse engine brak-
ing, shift toalower gearingood time. This
helps youtoavoid overheat ingthe brakes
and wearing themoutexces sively.
When making useofthe engine braking
effec t,itis possible thatadrive wheel may
not turn forsome time,e.g.inthe case of
suddenly changingor slippery roadsurface

If you rest your footonthe brake pedal
while driving, thebraking systemcanover-
