1998 XJ
2wd
4.0
AW4
8.25 rear axle with 3.55 gearing
165K
non-ABS
It's been a rough couple of weeks for the XJ. I made it through the PCM diagnosis and replacement, but now I have a new issue......the brakes.
Now, I know the braking system in our XJ's is not "cutting edge," but I'm having a strange issue. The brakes are "grabbing" and the pedal feel isn't what it used to be. I've adjusted the rears several times to no avail. Last year, the front rotors, pads, rear shoes, wheel cylinders and harware were replaced. The rear drums were turned as well.
I brought the Jeep into the shop today and did a full brake inspection. There's an awful lot of drag on the front wheels.....is this normal for a 2wd XJ? The wheel does not make a complete revolution before the drag stops it. At this point I was leaning towards perhaps a bad phenolic piston in my caliper or even a failing proportioning valve. I threw a set of gauges on the front and rear and I'm getting 1000 psi at the front caliper and 500 at the rear drum, which I interpret as normal.
So at this point, I'm leaning towards sub-par rear linings and perhaps aging calipers. The Jeep stops and I'm not worried about an accident, but it just doesn't feel the right. Any thoughts are greatly appreciated.
