Stock 97 TJ Anti Lock Brakes Problem

I did a search & found nothing, so here it is...

I have had 31 x 1050's on for several months, with
no issues. When I stopped in my driveway last night,
I felt the brake pedal vibrate. I thought I must have
stopped on some wet leaves, so I didn't give much
thought. Today, the anti locks engage just as I come
to a stop, everytime. Hard braking works normal.

Thoughts please.

Thanks!

Johnny C!

You have anti-lock brakes in a 97?

Get down on the axle and check the gear on the shaft and make sure that it's clean and free of debris. Also check the sensor to make sure that it is clean as well. Is the ABS light on in the dash?

abs was an option every year, i dont have them because they tend to annoy me. anyway, i had the same problem with a grand cherokee that i used to have that uses basically the same system. turned out to be a loose sensor and worked fine after i got it back in there, just wasnt reading correctly because it wasnt actually aimed at the tone ring, or whatever they call it. wasnt throwing a code either because it wasnt an electrical problem with the system, it just thought the whel had locked up when it really hadn't. later i ended up pulling the relay for the abs in the gc because something else went wrong and i was just tired of messing with it. drove it for almost 40,000 miles that way and never had another abs related problem.

Ditto, my '97 came with ABS on its original Dana 35c axle. X2 on checking the sensors. My ABS started doing funny things and lighting the ABS light and I discovered one of the ABS sensors on the driver's side front had road tar on it. Cleaning it off (and the other 3 sensors) with WD-40 and a rag cured the problem.

No ABS light on and brake fluid level ok, too.

I'll check the sensors.

I'll let you know.

Thanks!

Front sensors looked Ok from I could see, just now.
But it's way too cold for me to really work on it
tonight.

My rear brakes are drums. Do they have sensors, too?
I couldn't readily see any.

If I pull the ABS relay, I assume the non ABS portion
will work OK, and bypass the problem for now?

Thanks again!

Yep, the rear drum brakes have ABS sensors too. Follow the ABS wiring right to the ABS sensor, there is only one wiring cable going to the brakes and that is for the ABS sensor. And yes, you can pull the ABS relays to disable the ABS system. On my '97 TJ, there were two ABS relays. Once those are pulled, the brakes will continue to work normally. My TJ still has the ABS system installed but I have those relays pulled since the rear Dana 44 axle I installed doesn't support ABS.
