Next Gen Ranger brake controller delay


Hi all

I've been unable to get caravan brakes working properly with a new Ford Ranger (with integrated brake controller).  Hooked up to van in the driveway and it works, but it takes a 6-7 seconds before they activate.  I can hear the magnets humming straight away, but there is a delay until they grab.  Any suggestions as to what could be causing this?

Cheers

Paul

Welcome to the Forum Paul.

It sounds like you have a problem with actual controller not effecting a hard enough braking force. Can you adjust it up a bit?

Hi mate.  Thanks for your reply.  Unfortunately no, it's an integrated system in some of the new Rangers.  I've set the gain at 10 though (full) and the brake intensity at high and that's the result.  Do it sound to you like insufficient power coming through the controller?

If you jack up one side of van and spin wheel and apply brake hard, does the brake actuate and stop wheel.

I am unfamiliar with Ranger integrated brake controller, but many electronic brake controllers self set braking power and retain effect in their memory - your controller may need to be re-set by a Ford technician.

Humming magnets can be a sign of AC or pulsed DC. Probably the latter.
Magnet driver circuits can have a relatively high voltage to start which drops off to a sustain voltage.
It could be that the initial power(Voltage and/or current) are not high enough to operate the magnet or that the inertia in the pads (return springs) is too high
or you have a bad return earth.

It's times like this when you need access to an oscilloscope so you can see what the current is.

The controller has since been replaced, and I've found that the vehicle needs to be moving to send sufficient power to the brakes to activate them. Stationary, the voltage supplied is very low, obviously just enough to make the magnets hum. However once moving, there is now trailer braking which increases based upon the speed, and how hard the pedal is being applied.

So, thank you to all who posted, speculated, pontificated, and took the time to give your knowledge and experience. Hats off also to Ford for working hard to solve this issue.

That is the way most modern electric brake systems work. They use accelerometers to measure the rate of braking. Stand on your brakes, the van brakes hard, it is called proportional braking.

RE: Next Gen Ranger brake controller not effective


Hi all, I have 2022 Sport Ranger and cannot get any braking on my 20 van , I set all info numerous times , load on heavy , gain 6-10 , slide control works ok but nothin from pedal , tested on 4km 7% decent checked drums for heat , all cold , so no assistance at all to help slow both vehicle and van together . New brakes on van , tested all wiring , works perfectly on other vehicles fitted with Redarc but not on my $75k Ranger . Ford told me it all works as intended and said my van is not compatible with the new system with no help to get it working. My van is 2016 Opal with Alko 10 electro magnetic brakes which most vans use , very simple system so whats the issue. Can anyone help me please.Geoff R
