Tracking down a pesky vibration

[Robvoip]

So I've been dealing with a car vibration for a few months and can't seem to solve it. I replaced a set of rear pads and discs along with a control arm, to no avail.

So the car and pedal vibrates when I slightly brake at higher speeds (its really noticable at speeds between 70-80km/h), if I hammer the brakes, no issues.

In the past I had a rear driver side caliper seized and then rebuilt, I also noticed when I changed my pads that the rear passenger pad was more worn than the left (seems like it was stuck, so I cleaned and lubricated the brake, everything else seemed fine).

Will change the brake fluid and check my axel's again, but before I dump more money into this, has anyone had similar issues?

Not sure if this will help but are your wheels bend free and balanced as of recently?

[Robvoip]

Yep, alignment as well.

Did you do both front and rear rotors? If so why not replace the front pads also? The only time I had vibrations while braking was in my 200k mile honda and that just needed its front rotors replaced and anytime you replace rotors you should replace your pads.

No direct vibration in steering wheel, the front rotors and pads were replaced not too long ago.

I’d check the rebuilt caliper to make sure all the pistons are extending properly. If not, that would explain why it works when you break hard
