If the rust spots are evenly spaced, you can use surface stitches to cover them. Good stitches might be Smyrna cross stitch, satin-stitch heart, queen stitch, satin stitch lozenges/triangles, palestrina knots, etc. If the spots are not evenly spaced, balance the design by adding extra stitches between the spots.
Fortunately, most states require drivers to equip their trailers with brakes and devices known as brake controllers. When a driver presses on the brake pedal in his truck, the brake controller lets the trailer's brake system know how much braking power is needed to stop the trailer.
Best Answer: Covering the brake, is to be able to stop quickly in an emergency situation. Controlled braking, is to apply the brakes as hard as you can without locking the wheels. Threshold braking, means to utilizing the maximum potential of your brakes, or in other words, braking to the threshold of locking-up.
