Pop,clunk bonk POS truck

Something else is loose...keep checking. It's hard for us to fix stuff without seeing it

Yeah what the other guys said. Something has to be loose if its clunking.

Is it loud? Maybe something caught in the wheel somewhere. Brake issue.

Hows the weather there? Ice or something stuck in there? That happened to me before. Especially after wheeling in the winter.

Sunny and there is no snow. It's been doing it since September but just recently started getting more pronounced

could it be your caliper pistons (when not pushed) are slightly recessed into the caliper allowing the pad to wiggle and clunk? brake pads are hella dense and that much mass hitting a spinning rotor every now and then would be very noticeable. makes sense to that you slightly touch the pedal and its gone...Ive seen it happen where caliper pistons dont hold when pedal is depressed

Don't be mad at me asking but have you checked your wheel nuts? :p that is the exact description of what loose wheel nuts sounds like

Ok I found the cause. If I grab the back side of the caliper I can wiggle it. The sliders are tight and the brackets are more than tight. I think rangerrunner11 is right not sure tho let me know what you think. Also a lot more noticeable with the mud terrains I put stock tires and wheels on and I could only hear it but it wasn't as noticeable but still there. I think the MT is wiggling the crap out of it.

sounds like someone needs to get some locktite, a BFW, a good arm and reset your caliper bracket bolts as well as the caliper bolts themselves.

oh and make sure all 4 pads are there as well lol

Ok so the Caliper bracket bolts that go into the knuckle how would the effect the movement of the caliper? the Caliper is wiggling (made a video) but I'm confused i have never ever seen this happen.

there are 4 bolts in each set up.

2 hold the caliper to the bracket, and 2 hold the bracket to the spindle.

sounds like the caliper bolts themselves are loose.


the two bolts with arrows in this pic are the ones im referring to, they hold the actual caliper to the brake bracket

It's super annoying driving and the passenger side doesn't. Nor do any rangers I've tried?

no, your calipers should never wiggle lol

if the caliper and bracket are both tight then the only remaining option is to bleed the **** out of your brakes.

Theory being: air is down in the line, close to the caliper and when you let off the brakes the pistons in the caliper retract allowing for a little freeplay, get the air out, stiffen up the pistons response and maybe thatll fix it.

kinda sounds like time for new calipers

on mine it's only the passenger side that does this, and that caliper was installed 2 years ago, it's been doing it the whole time.
