Hey , I installed a pair of elec brakes on my old trailer, left and right ! . After instal, when jacked still, testing, brake controller in truck stopped wheel from turning, but not foot pedal. No codes, 2016 sierra HD. when on the road, no diff. Chnged the 30 amp fuse. The dash says the gain is rising when pushing the pedal, but the wheels don't seem to be slowing ( I can usually feel when they are active) . When I hooked the wires up, i left about 4 inches of the old brake wire and hooked to that, should I have removed this section ? There was not a lot of wiggle room in the wheel well ! Thanks for any hep. M
The way you are testing the system may be part of the problem. If the camper is off the ground, you spin the wheel, press the manual button on the brake controller and the wheels stop, OK that at least tells you the brake coils are getting some power. But it does not take much power to stop a wheel off the ground.
When you are towing the camper, say at 20 mph down a empty road, if you press only the manual button hard, does it slow the camper at all? There are no truck brakes in this test, you are testing the mechanics of the brakes and the wire from the controller. If you do not get some braking feel in this test, then there can be a mechanical issue or a wire issue not able to deliver enough current. Did you adjust the brakes and if so, what was the feel you where after in adjusting them?
Did you burnish in the brakes yet? You may not have, but it will need to be done before good braking will happen.
You need to sort out, is the trailer brakes correct, and then add in the truck brake pedal test.
You can also do a drag test. Unhook the 7 wire cable from the truck so you do not back feed the brake controller with camper electric. Pull the emergency breakaway switch, drive real slow forward, you should have brake lock up or a really hard drag. If this does not work, you have to back into why? This then points to the trailer has an issue. This test also assumes the break away switch is working. When the switches get old, they have been know to not work, corrosion in the switch stops current from passing and creates a lot of heat in the switch. Point, if the drag test does not work, make sure the breakaway switch is passing 12 amps if you have 4 wheels braking.
Hope this helps
