F-53 brakes

Ok, were searching for a upgrade in MH. We've drive Coachmen Midira's, Jayco Precepts and Itasca Suncrusier.

It seems to me, the brakes on each of these similar sized vehicles reacted differently. The Jayco drove the best but the brakes seemed soft. Are there enhancements that are / can be made to the F53?

There are no brake enhancements that I am aware of. However you didn't mention what year motorhomes you're looking at. If they are more than a couple years old it could be that they have water in the brake fluid. Ford recommends flushing the brake system every 2 years.

Also there's a world of difference in the feel of the brake pedal between the older series chassis with the 2 valve per cylinder engines and the newer series with the 3 valve per cylinder engines. The older ones have a softer pedal feel much like a car. The newer ones require more pedal pressure.

In addition there are 2 different power assists depending on the size of the chassis. The lighter 16,000 lb. and 18,000 lb. chassis use a hydro boost system with a 8.19:1 boost ratio. The heavier chassis (20,500 lb. 22,000 lb. 24,000 lb. and 26,000 lb.) use a Hydromax system with a 21.1:1 boost ratio

When we went from our 2001 motorhome to our 2103 motorhome (both on the Ford F53 chassis) we noticed a difference in the amount of pressure needed on the pedal to stop the motorhome. The older one took much less pressure. However after a few thousand miles of driving we are now used to the amount of pedal pressure needed on the new motorhome.

If the chassis had different GVWR ratings, the F53 brakes may be physically different. Two different sizes are used, and two different power-assist units. The brake size changes for GVWRs above 22k lbs, and the power booster changes at 20,500 lbs (see Hikerdogs comments above). This is from the 2014 chassis specs, but recent years are similar if not identical.

Sometimes a coach builder will skimp a bit on the chassis size (GVWR and wheelbase) to get the price down. Usually a poor tradeoff, in my opinion, but many people seem more interested in price than anything else.

A heavier coach may also give a different perception about the braking, even though the brakes are physically the same.
