My abs light is coming on and making a pulsing sound and then squeeling realy bad. Causing me to press on the breaks realy hard. Anyone got an answer or solution for this?

have you checked fluid? idk too much about abs... is there a pulley for the abs motor that is dragging on serpentine belt? idk...

Cbass0812

Its good on fluid and I dont think it has a belt driving

The pump

Sounds like the EBCM (Electronic Brake Control Module) is self activating the ABS. I am not to familiar with the design on the XJ's, But it could be a number of things. Used to have this problem with the Early 00's C and K series GM Trucks.

I would have someone scan it and see what code its throwing. A generic scanner wont do the trick you will need one that does ABS.

For future reference to anyone. The ABS pump does not run off the engine from a pulley. It's a totally different system then the Engine.

what year jeep ? 1990?

It is a1991 briarwood 4.0 HO

my guess is a/the speed sensor is droping to 0 while driving indicating a wheel lock up situation, in turn causing the ABS pump to run and correct the lock up condition that dont exist.

I think once all that acts up and goes bad its junk. It wasnt a good system at all from what i found out about mine , it is a 1990. I just took all that stuff out and put in a 1995 xj master cylinder and booster. Parts and warranty at pull a part was $25 i should be done tomorrow

one of the front sensor/tone wheels is where i would look first.

How compatable and how much of a pain in the neck would it be to do that where would it go?

If you have the bendix ABS system its not that hard and supposed to be worth it. i should know today. The swap isnt hard. you just need a donor 95 cherokee and up 98 or so, not sure how new you can go. Searxch abs conversion or bendix conversion on here there is tons of info. I got $25 in parts with a warranty,i got maybe a day in it and thats even a trip to pull a part and hunt and remove parts

Cbass0812

Thats not bad at all! Dumb question for ya how do I know it its the bendix system or not?

I think by a little pressure ball next to the left master cylinder, no booster either
