Is the brake rating applicable to downhill as well as uphill for towing?

The maximum weight of a trailer able to be towed by your vehicle will be outlined in the vehicle’s owner’s manual. This will specify weights for trailers with brakes and without brakes. These weight limits take into account the effect of the trailer on the vehicle’s overall safety performance and durability. If the trailer is within the vehicle’s specified towing weight limits and the vehicle is properly maintained, your vehicle will be able to handle the loads of a trailer that is within the appropriate limits. Of course, extra care is always required when towing, such as using the appropriate gearing when descending and ascending hills.
