Thread: Vibration during braking - thoughts?

Hey guys, I've got a quick dash cam video for you to watch. I was out driving down the canyon, pushing the car a bit but nothing too crazy. During the last two or three turns I started to notice a slight vibration when I was on the brakes, then it got really bad as I was on the last turn before the light. I couldn't replicate it again after that. Any ideas what it might be? I don't think it's the ABS acting up. It felt different than that. Almost like something coming loose but I don't know what.

Link to a video of it. The vibration is quite audible for a few seconds.

Thanks

Check the caliper bracket bolts, I've had one back out completely and disappear, it was the top bolt, front passenger side.

I didn't have time today to actually jack up the car and look closely at anything, but all the caliper bracket bolts are present and appear fully tightened from a visual inspection. I drove the car as usual today and still could not replicate the problem. I wonder if it was caused by the car getting hot somehow. I guess I won't worry about it again unless I see it happen again.

Likely it was as you think. Without knowing pad composition and quality of rotor, it's all possible. If you can't replicate it.. smile and keep on driving

That's the plan I guess. I'm on what I suspect are original or OE replacement rotors, and I put PowerStop Evolution ceramic pads on the fronts shortly after I got the car (I think I still have cheap organics on the rears that the used car dealer installed). I wasn't on the brakes all that much going down the canyon though.
