never really had a very firm or hard pedal in the time I've owned it.Integral Parking Rear Calipers. My pedal is a bit spongy, but it's been like that since I got the car. Hopefully that will shed a bit more light on things. I'm going to try to get the fluid changed and the brakes bled this weekend if time allows. But the sound is almost like the caliper cylinder is putting just enough pressure on the pad to make a noise, but not putting any pressure on when the pedal is pressed. When I did the pads and compressed the cylinder in the caliper for the new pads, it compressed just fine. If I pull the caliper off and spin the rotor there is zero rubbing sound, it just spins like you'd expect it to. The thing that had me thinking braking system is this, when I lift the car and spin the back tire or rotor with the tire off, I hear a very similar sound just not as loud, probably because it's not under weight or as fast. Not a wobble sound or weird rotational sound, I've had hubs go bad, this is more rubbing than a bearing going out. If it is rubbing, it's no matter if I'm coasting, in neutral or in gear, when I apply the brakes there is zero discernible change in sound other than no noise while stopped. Sometimes from a stop I'll hear nothing out of the ordinary. The sound is there most of the time, but lately not every time.

Yes, I did hear the sound for that last month or so, before changing pads and rotors on the 18th, just wrote it off as needing to replace parts. What are the odds of both calipers having the same exact problem, at the same time?Ĭar has about 148k miles. How do you perform a diagnosis on the master cylinder? I have a funny feeling that's where my problem lies. But I'm not convinced that's the true problem. Now admittedly I do need to change the fluid, I sucked some out of the res today and it's dark like tea, and do a complete bleed/flush. When I took the wheels off yesterday and saw this, I did the same, same slight sound when I spin them by hand. Now before originally putting the wheels back on after getting everything back together, I spun the rotor, and there was a little bit of a rubbing sound on both sides, just chalked it up to new pads and rotors, and figured it would go away when the pads bed in a bit. The pistons compressed just fine when I went to fit them for the new pads, so I don't think they are seized, and definitely not sticking. This is what the rotors look like on both sides, after about 100 miles, give or take a few. I had new rear end links coming, so I pulled the wheels off to get them done. Took it for a drive and it's still rubbing someplace.įast forward to yesterday. Convinced this was the cause of the rubbing sound finished up the brake job and put it all back together. After not being able to find the parking brake rebuild kit in stock locally, and having a wedding to get to, I put that side back together without the adjusters or parking brake pad. I found out the passenger side parking brake was sticking. This past weekend I did rear struts, pads and rotors. So for a while now I've had a rubbing sound coming from my brakes.
