OK, so I replaced both the master cylinder AND the front brake hoses... and the pads are still dragging! I know there isn't much of a gap between the pads and rotors to begin with, but when I can hear the pads rubbing while riding down the street, I still think there's something wrong. I'm just worried that they're TOO close and rubbing TOO much that the rotors are going to get super hot and warp. Are they working correctly and I'm just being overly paranoid? Is there something else I need to do?
Note: I can turn the wheel/rotor manually. And the Jeep will move, there's just a lot of rubbing going on.
EDIT: I put the old pads on, just to check spacing... thought maybe the pads were too thick (I know, stupid, but I'm drawing a blank on what else it could be), but even with the old pads, the caliper will close all the way and then not back off enough.
(blackolive: Yep. Doing the night school thing rather than the apprentice thing. Doing conduit bending this month. )
Dust shield... is that the plate that is on the back side of where the rotor sits? I'll check, but I would think that would sound a little more... metallic sounding (I guess). What I'm hearing is definitely a... smooth sounding rub. As if a sound can be smooth, but I think you get the idea.
So just went to get some baby pictures taken, and the rubbing sound is still there. And the Jeep seems to have to work harder in order to go. When I pulled in to the house, I could feel the heat off the brakes, even though we are having rain and most of the last driving was highway (i.e. no stop-and-go).
I'm wondering if it's the calipers. They're Autozone remans, and I thought I read around here someone's opinion that they aren't the best. Thoughts?
Finally figured it out: I should have paid more attention to the suggestion of looking at the dust shield, because that's exactly what it was. After getting a second set of calipers (this time from Napa) and changing them, I thought about the sound I was hearing. It was constant, even when I was braking. In my mind, if it was the pads making the noise, the pitch/tone/sound in general should have changed. So this time, when I put the new calipers on, I took the rotor off first. And lo and behold, there were some nice scrape marks on the shield as well as some spiffy grooves in the backside of the rotor. I banged down the shield with a hammer as much as I could, and the scraping has all but disappeared. I get it every now and then when I'm turning, but no biggie.
My guess? Well, as I mentioned before, the previous rotor was a composite rotor and the hub measured out for a composite rotor, but the bolts always seemed longer on mine than what was in that picture that was in the brake rotor thread linked to earlier. And that always bothered me. I'm thinking that the hubs got replaced, maybe the bolts were swapped out... needless to say, I'm going to take it to a mechanic to get the drums replaced, because I'm tired of dealing with brakes for a while!
Speaking of mechanics, any suggestions on a good place to go and have the drums replaced? I could go to the dealer, but figure they're going to be more expensive than some other place that can do just as well.
