y u use breaks so much on steep ,, your Car never get heat up ,, use minimum breaks on steep ,, use gears when you need to slow down your car you pull down the gear from higher to lower gear ,,, and so you dnt need to stop over after every 15 minutes...
tips is : never gear free your car when you are on steep road.
precautions : when you use too much breaks on steep road, it might get problem for you and a big cause of accident is , your break leather shoe may get over heat and cause break failure. so be carefull and use minimum breaks, stay low ,use minimun breaks, use your gear to slow down,,,thanks
and when you are on climb move higher altitude use your lower gear as maximum and dn't neeed to speed up, when u have a small capacity car, and use zigzag technique too....
