BRAKES SURGE WHILE STOPPING - NOT PULLING OR SHAKING THE WHEEL

2003 Ford Ranger • 97,600 miles

I have a 2003 ford ranger with 97600 miles.

When stopping at a slow speed or fast the vehicle surges as I stop.

Not from the pull of the engine, (Clutch is pressed), manual transmission.

IT really feels like they are grabbing, then releasing. Similar to what you

might expect when rotors are warpped.

The pads where recently replaced on the front, but they did not turn the rotors.

The rear brakes are also new.

No ABS light is on.

E brake is strong and works.

I was thinking of pulling the ABS fuse to see if ABS was doing this.

What are your thoughts? I am thinking I may need to have the rotors turned and the brakes bleed.

thoughts?

Did you try pulling fuse?

No not yet, I understand that there are 3 fuses. Will pulling on the one inside the cabin work or do I need to pull the ones under the hood also?

ABS control module #14

ABS pump motor #6 (Distribution box under hood)

Okay, the ABS exacerbated this tissue, but its still there only not as bad.

Tonight, I am going to pulled the front rotors, have then checked for alignment.

Replace if necessary and bleed the brakes.

I will then test with out ABS, if it stops cleanly, then I will re-install. Fuses and retry

Okay, found the issue,
friggin rotors. Despite the fact the local shop said they were good, the machine shop said they were not and they were right.

When they put them on machine they where out of round.
Since cutting them true would have gone under required safe thinkness I simply replaced them.

Now, stopping is smooth and quick.

Thanks, I hope this helps others
