brake pad moving, how do i fix this
Need help on brakes/pads asap, pad is moving making noise
hey everyone. havent been on the boards lately and posting but i have been still looking through. anyways i have had a mysterious noise coming from my driver's side front tire when i go slow and make turns while stepping on my brakes. it made a loud metal to metal noise like a hitting noise kind of like a clunk. or clicking noise. anyway i took my tire off just now to check it out. i thought it was the pads or rotors and it comes to find out that the outside pad is loose and is moving and hittint the control arm making this noise. it kind of slides or shifts from front to back. just a hair enough to make contact with the control arm to make that noise. the control arm has an upper and lower support that is supposed to hold that brake pad in tight and stop it from moving.

anyways my front outside pad (the one you can see when looking at the caliper) is shifting and hittint those control arm suports. the pad isn't supposed to move at all and be tight in its place, mines not therefore making that noise. my question is how do i fix this? how do i stop the pad from hitting the control arm making tihs noise? this noise really bothers me but i know its not hurting anything but it is bothering me and it shouldnt do this. thers no shims or anything to put by the pads so i dont know what to do to keep this pad in place? how do i fix this asap? lmk guys. have you guys had this problem before or one like it? i hope someone can help me out to fix this i need to asap. thanks again, sorry for the long post just tried to make it understandable. any questions ask me thanks.

 

can anyone help me with this. im sure u guys know something. thanks

 

Do you still ahve the small metal pad retainers? They are what keep the pads from moving or rattling, should be 3 per caliper.

 

what metal pad retainers? i dont have those retainers. theyre not on my other set of pads on the other tire and i changed my pads about a year ago. are u sure there are those retainers. didnt come with my braeks haha. well ill call gm and ask them about it. thanks.

 

sorry for the double post, just now noticed that. also does anyone have these retainers? i know i didnt. well lmk thanks. ima try the stop quiet and layer it real good hopefully tha will help some as vegasz said. thanks.

 

anyone have any more ideas sugestions? i hope you gusy have had this problem before. i know i dont have the retainers. and i havent got a chance to use the brake quiet but will soon. thanks.

 

It gets a little confusing when you start talking about "control arms"..... I think you mean the big horizontal bars on the steering knuckle. The pad has to be loose enough to allow it to slide on those bars as the pads wear and the caliper has to move more to squeeze the brakes. If you are hearing a "clicking", its possible that you have a warped rotor, or high spots caused by deposits on the rotor, that lifts the pad slightly as the high spot passes, then "drops" the pad after the high spot gets past the pad.

The outer pad is held in the caliper with the two spring clips fastened to the pad.

 

yea i do mean the steering knuckle. those two bars are what line the pad up to stop it from moving. they are like supports. yea the outer pad has those two spring clips that fit on the caliper. i have them put in right and i know my rotors arent woraped. its moving forward and backward hitting those two suports ont eh steering knuckle. i know this for sure because i can move the pad by hand. it only moves about 3 mm or so not a great amount at all but enough that when it hits the steering knuckle bars (supports) it makes the clicking noise. i am 100% that is what it is and i am just wondering why those supports arent holding my caliper in right the other side is fine. i have had them on for a year and they are barely worn down at all. lmk if u have any suggestiosn thanks man.
