2001 Suburban brake problem

Welcome to the forum.
The signal from a wheel speed sensor is probably dropping out. This simulates a wheel locking up and causes the ABS to engage. You'll want to get that serviced. If it can be reproduced readily, they'll hang a scan tool and figure out which one. Otherwise, things get interesting as far as diagnostics go.

P.S. Oh, it's now "Car Performance Chips," is it?

I might have the same issue
New member to this site and have a 2001 Suburban I really like. I had the parking brake fixed several years ago and since than the ABS and Parking Brake light is on most of the time. Didn't seem to bother anything so never fixed it. Now when I am braking I get this pulsing in the pedal along with vibration from the front wheels until I slow to a stop. Checked the brake pads and they are good. Is this the ABS system malfunctioning?

Welcome to the forum. The ABS is disabled when the ABS warning indicator is on. Thus, I suppose the ABS warning isn't actually on during these incidents. Get it serviced (at least get it scanned and go from there). As heavy as the Suburban is, I'm surprised that you've been ignoring an issue that has to do with the brakes.

sounds like it wasnt fixed if the light was on after the repair. If you don't have quick access to a scanner I'd start at the rear wheels and look for anything damaged from the parking brake "fix"

Thanks for the input. I'm sure there was a problem after the brake repair but figured it was a senor issue and just ignored it as we weren't driving it that much. I'll get it checked
