    Hello
    My car
    2014 prius
    I recently changed my front disc & pads
    All Toyota parts & lubed my calliper pins
    & cleaned & brake kit reused & cleaned
    I have took apart 3 times &refit double check
    Done about 1000 miles since

    first few miles no sound ,
    Then it keeps coming
    Very noticeable rubbing
    Seems to stop when braking this is noticeable
    @ 5-15 mph window down driving
    I jacked car up
    Put in neutral
    & spinned wheel can’t hear it seems fine

    any suggestions please

    Any loose panels underneath?

    does the sound change with speed? Turning?

    Just wanted add
    The disc is not shining with these pads ,not bedding as nice as I thought , I accidentally got grease on them , I after few hundred miles I did take apart & cleaned with brake cleaner , including pads , I’m thinking did I ruin my pads ,
    & the pads plate shims are not solid tight but are on don’t seem to move ,

    I’m lost what it could be

    thanks for all reply

    Help the grease car lube lm2 white ,

    also when I’m braking there’s a brake beep when I release brake , it also skids under really hard full stop brake

    I’m thinking replace pads ,
    Because I had some anti seize tiny amount on pad surface which I drove for 100 miles ,
    couldn’t get the disc shiny after I cleaned

    Googling “lm2 white” I get no relevant results. Post a picture of the product?

    For what is worth, this is what I’m using:

    for caliper slide pins and rubber boots:

    sil-glyde brake lubricant

    for contact points between pad backs, shims and caliper:

    Permatex Anti-Seize (silver)

    someone may be along shortly to correct me, suggest Toyota proprietary lubes.

    I am thinking that you should let a professional mechanic fix them right.

    Yes, you probably damaged the pads.....with grease or anti-seize or whatever it really was.

    It is not a problem if the ABS kicks in and the tires skid a bit under REALLY hard braking.

    I don't think you have the knowledge necessary to be doing things like this.

    The one time I've had ABS going off under normal circumstances, was after a "professional" brake fluid replacement that left one rear corner non functional (free-wheeling). This was on a previous car.

    Any idea what the brake beep noise is ,

    it was there before I did the disc brakes ,

    it does seem worse now ,

    I did the rear as well full disc pads no issues there , supposed to br harder I’m told ,

    I also noticed a crack on brake flex pipe , no leaks ,
    & brake fluid colour looks old
