Hiya,
As i've mentioned in my previous post, its cheaper to brake harder
than to engine brake more often cause:
1) Brake pads are cheaper compared to the wear on your
gearbox
2) Engine brake with the intermittent jerk consumes more petrol
cause its a sudden downforce.
3) unless u know the proper techinique of heel & toe to keep
the rpm constant or minimal drop, up if not ur gearings will wear
in no time as well u will have to visit the petrol kiosks more
often.
4) If you constantly engine brake, that will reduce the life span
of the gearbox to 1/2. Wat could be a good practice would be to tap
on the brakes hard once to reduce the speed of the car then slowly
downshift.
Oh sorry yours is an AT car right? then Brake hard the 1st round to
reduce speed then intermittently brake till u get the proper speed.
However, this technique requires good judgement of speed.
