New brakes are hopping

[tomthyme]

Well, I had some new brakes installed on my rig. They are electric drums on a 16k carriage cameo. On the way home from the shop today, I had to stop quickly. The rig started hopping like crazy. I backed down the gain and it got a little better. I eventually backed off almost 50%.

So, was the hopping caused by too much gain and my brakes locking up? Or was it something else?

Thanks so much folks!

Check your suspension for loose or worn parts. It should have just squatted and slid the tires.

I would think too much gain for the new brakes.
