hello everyone.. Almost 6 months ago i changed my front left rotors stud bolts, since then i noticed weired noise while lightly pressing the brakes, changing the bearing and the rotors and brake pads the noise dissappeared for a while, but now when i push on the brake to its full while turning the weels to whatever side this noise appears I have visited so many mechanics and no ome had any clue,,, Any suggestions please.
You need to grease your caliper bolt pins and put disc brake quiet on the back side of your pads to make the noise go away. Make sure your lug nuts are on tight = 80ft lbs. When you turn the wheel the rotor should be solid with the rim and caliper bracket.
wow, it sounds like a spring being tightened, but i don't think there are any in there. how many km's on her?
3 of my rotor studs broke while changing a flat tire (i still dont know wy they broke), my friend offered to install new studs and obviously he did it wrong , he hit the studs into the rotor with a hammer
hmm, i'm not sure of the proper installation method, possibly pulling them in by snugging up the nuts to the proper torque? i'm not sure what damage hammering them in might do, you've already replaced the bearings. maybe you need to disassemble everything and start over. the big question is why the noise would go away for awhile with new pads and rotors. a slightly bent axle might cause them to wear unevenly?
I think the anti-rattle clips, the brass-plated clips at the ends of the pads, are installed wrong, or broken, missing a piece. Maybe. Here's a screen-grab from the video: And here's a pic of ours, again, left side front rotor: Or, is it a different anti-rattle clip design, different part of the world?? Also shim pads appear to be missing.
Stud failure, a couple of things come to mind, Firstly, over-torqued lug nuts. This is the obvious one. But also, maybe just removing the lug nuts when the wheel is hot, heat-expansion of metals might have led to seizure?
Thank you for your response,, i managed to install the shims and replace the clips with new ones, seems to solve the problem for a while then it reappears, not to mention that the sound appears only on the left side not on the other Another weird thing that it appears after a heavy use of brakes and when the car is heavy, and after a day or two of not using the car it is managed to go away.. it drives me crazy
Yes it supposed to be pulled not hammered in... I will try to capture another clip maybe from inside this time It may help
The sound actully appears when the wheel is hot and with heavy braking,,, and declines with cold and rainy weather It might be from the lug nuts ,, i will change them and hope for the best
Just another thought: the wheel should not get any more than slightly warm normally. If it's very hot, say due to excessive brake drag, for whatever reason, that again might have heated up the studs enough that the nuts seize when you attempt to remove.
