I have driven about 60M with three axle disc brakes and the DirectLink controller. I am now concerned that if I use maximum breaking someone will rear end me. My rear view camera scares me. I would never go back to electric brakes. Airstream has done a good job on them. My only expense has been one set of inexpensive new brake pads (Chevrolet). I do recommend Dexter electric over hydraulic pumps and single cylinder calipers.

What is Dexter Electric disk brakes? I thought all of the disk brakes used a pump to activate hydraulic calipers.

Clarity... we must try to be 'clear' in our communications..

How Does the Dexter Electric Over Hydraulic Trailer Brake Actuator Work | etrailer.com

'Disc' brakes are 'hydraulically' operated in most cases. Exceptions would be few.. so, let's stick with the assumption that we are dealing with a 'standard' disk caliper and rotor setup...similar to a car.

Essentially, in older cars, the Master put fluid to the caliper 'piston', engaging the brakes. In 'newer' cars, like with ''antilock braking"(AB) module, when you step on the pedal, the fluid sends a 'signal' to the AB. The AB then applies 'programmed and appropriate' braking fluid pressure to each 'wheel'/disc brake piston. (This is not a AB system discussion, the point being the 'AB' module actually controls (pumps) the brake fluid.

In the 'Electric over Hydraulic' as stated in the link provided above, the 'signal' is sent to the AB (brake module) by pressing the brake pedal via proportional voltage sent by the TV 'brake controller'. The AB then applies pressure to the brakes (disc calipers). Press harder, more 'boost' / increase in pressure to the calipers...

That I knew. So all disk brake system for trailers are electric over hydraulic. Dispite the complexity, I think the better brakes are worth it.
