One hasty plea before bed time: I do wish that writers of historical fiction would check their facts before making their heroines attempt anything with horse transport other than sitting decoratively inside or on the box seat.
A man driving a team of 4 horses would have a groom sitting or standing behind on the carriage to attend to them in case of difficulty or breakage. He would not need a heroine to interfere.
Horses attached to carriages cannot be held still by a brake - especially when at the date of the story brakes on wheels were yet to be invented. Even when brakes had been invented, they didn't work as a "parking brake" in order to leave a team unattended, not even if the heroine ties the reins to the pole (not something I would attempt in trousers, let alone in a dress). Our author is thinking carriage = car. Not so.
And for goodness' sake, tidy up typos and wrong words and run-on comma-punctuated sentences before you stick a story onto Amazon Kindle.
