I'll try and have my buddy use my camera tomorrow to do it tomorrow.is there any way you can get a video of this?
It's coming from the rear, sorry I forgot to mention that.Is it coming from the front or rear?
Yeah I was thinking of doing something with the BPVMaybe you have the same problem as me. My rear brakes squeak with a drop and bigger wheels but is fine when stock height with steelies. I even lowered the BPV hardware on the pumpkin and that didn't help anything. The brake shoes have 45 angles on the ends also.
Yeah I'm thinking I'm getting too much pressure to the rear right now...not too much where they lock up(so at least the valve is doing it's job), but enough to be ab-normal for what's going on(no weight in bed)if its a chirping lathe noise, ur drive shaft is hitting something. you can check that by looking for a shiny spot on the drive shaft.
ur proportioning valve itself wont cause any noise unless its fallen off, if your lowered 5 in the rear, with the valve adjusted all the way down its still supplying your rear brakes as if you had ur bed filled, consider flipping it around to the underside like in my build thread. that will apply less brake and actually gives adjust ability (mine is a 6 inch drop in the rear)
if all of that doesnt get it to stop, you probably have glazed rear brakes from the pro valve, take off the drum and use a light sand paper on the drum and pads, clean off all dust with brake cleaner, see if that does it
Hmmm that 2nd statement you said makes sense..i re read what i wrote about the proportioning valve, and that'll just balance your breaking out to 80/20 or whatever its supposed to be.
if you adjust your brakes they'll still squeel, I think they're glazed from being used 50/50 from ur valve being all the way up after the drop
just use 100 grit like proteus said and you'll be set, remember to do the drums and the pads
or you can run it down a dirt road with ur foot lightly on the brake
fix them now. trust me on this. dont put off really bad u joints. it will be hell if they go out while driving.This sounds like a problem I am having. I suspect it might be the U-joints or the Cardan joint. The noise is a high pitch screeching noise when I press the gas, I checked the driveshaft and noticed a loose and un-greased u-joint. I plan on replacing them soon and see if that fixes the problem.
