Vibration under braking

[crankyoldguy]

Just picked up a 96 GW with a Hannigan conversion.
Has a vibration from the left rear when braking, At least it sounds like the left side.
What is the best way to jack these up?
I also bought a used older Escapade trailer and it has a 6 pin round connector. The trike has 5 wires wrapped in tape coming out of a split loom by the hitch. What colors are what? Or is it time for a test light and a helper?
These things sure sit low. I hit bottom a lot living on a dirt road.

Welcome .... lots of info here, someone will chime in on how to jack it up and the wiring.

Well firstly, thanks much for joining the Hannigan Owner Family. Wishing you many safe miles and endless smiles.

There are two Methods to Jack-Up your GL1500 HMS Trike:
1. If equipped with Trailer Hitch, place the Floor Jack Plate under the Hitch Assembly where the Outboard Angle-Braces join the Main Tube and lift. When desired height is achieved, place Jack-Stands under the rear corners of the Main Frame.
2. If Not Hitch equipped, place the Floor Jack Plate under the Diff (Pumpkin) and lift. Due to our In-Line Drive-Shaft/Offset Diff Design, the "short Shaft side" will lift quicker than the "long Shaft Side". Lift slowly and some find it helpful & prudent to have a 2nd Person on that "long side" to provide stabilization by placing their hands under the Body Fender Well edge and steady that side till lifted and Jack-Stands are in place in the same locations described above.

Trailer Wiring Color-Code:
BLACK=Ground
BROWN=Running Lights
BLUE=Right Turn
RED=Left Turn
WHITE=Brake
Of course, confirming with a Test-Light or Multi-Meter is always a good idea to be sure the Functions are the same as when applied here at manufacture. Little time & effort upfront can save you from Issues and re-work later.

Unfortunately, can't help much on the Dirt Road bottom-out situations. While you have it Jacked, check to insure the Shocks are in the 3rd/middle Pre-tension Setting. If they are not now, make them so.

That may help.
If that isn't the Case, call the Highway/Road Dept....



Hope the above helps.

Should you need anything else or to discuss further, please give us a call now or anytime.
All the best to you and yours!

What could be causing the vibration when braking

 

[Gorilla]

Disc or Drums in the back?

 

[Hannigan Motorsports]

Disc Brakes.
That's ALL Hannigan has ever put on our Trikes.

Obviously, the Rear Brakes (Assembly & Parts therof) would be the Primary Suspect with any Rear Vibration while braking Situation.
Should that not be the Cause in this Case, please give us a call.

 

[FuzzyWuzHe]

Check for foreign debris in the pads, I had a tiny stone stuck in mine and it cause vibration and some noise.

If the pads are good then I would look at a warped rotor. They might have got it too hot going down a steep hill riding the brake.
