Brake Pedal kick back
Well, now that life has calmed down a bit, I can get back to working on the ole XJ.
1987 Wagoneer, 4.0, AW4, D30, D35 for what it matters.
Experienced severe, random brake pedal kick back today on the way home from work. Brakes were fine all day, then it randomly kicked back. It seemed to be coming from the driver's front, and it was scary enough that I though I'd find the caliper dangling by the brake line, wrapped around the axle.
No such luck. Up on jack stands, both front wheels off and everything is "toight like a toiger". The only thing I could find, which needs to be addressed, but doesn't seem to be involved, is that somehow the dust boots for 2 of my 4 tie rod ends have come off...
The rotors have no grooves and to the naked eye don't look warped (I know I should have them checked), the pads are about 50%, all bolts, etc are tight.
Thought it might be in the pedal / booster mechanism, but the under dash parts and pieces look good. By the time I got under the hood, it was too dark to do any real looking.
Put the wheels back on and drove around, but couldn't reliably reproduce. It would happen under hard and soft braking, with no rhyme or reason.
Any thoughts? Should I be looking in the rear as well?

Wouldn't that just cause the brake pedal to stick and not forcibly kick back?
Thanks for the suggestions!

Yeah, but it feels really hard, like something is pressing back on the caliper or drum piston, not like I lost power. It kicks hard enough to send my knee into the steering wheel. Was out at lunch listening a bit as I drove around the parking lot slowly. Hearing a definite dragging from the rear, so I think I borked something in the drums and need to take a look. That's my next COA.
Give me a day and I'll get back to y'all.

I'm very wary when it comes to brakes...
