ABS brake pulse problem

[Copalm63780]

Alright, so I have a 2007.5 Chevy Silverado 5.3 4x4 and the abs has been acting up since I got my cam and lifters swapped. I read up on it and already changed my hubs and wheel speed sensors all around and the problem is still there. It's only driving slow and applying the pedal that it happens.

Slow,like 5mph and under?and just one wheel?

The first question that jumped out at me was what cam was swapped in? If it is a "performance" cam that lopes at idle from increased the lift/duration it's probably a low vacuum problem. A vacuum canister or hydro-boost swap should straighten it out.

I would think coincidence that it happened at same time, unless a wire was injured,the abs is electric signal,so loss of signal,it thinks a tire is skidding,so abs activates

You'll need a better scanner to pull the abs codes which will give specific wheel,, sensor, etc
