Additionally Dynamic braking is blended with this to achieve a higher braking force and reduce brake pad wear.

Famous quotes containing the word current:
“We all participate in weaving the social fabric; we should therefore all participate in patching the fabric when it develops holes—mismatches between old expectations and current realities.”
—Anne C. Weisberg (20th century)
“This is no argument against teaching manners to the young. On the contrary, it is a fine old tradition that ought to be resurrected from its current mothballs and put to work...In fact, children are much more comfortable when they know the guide rules for handling the social amenities. It’s no more fun for a child to be introduced to a strange adult and have no idea what to say or do than it is for a grownup to go to a formal dinner and have no idea what fork to use.”
—Leontine Young (20th century)
