I changed the front pads and rotors about 2 weeks ago and since then the car didn't really brake the same. It felt mushy. So today when I was changing the oil, I bled the brakes. That helped the peadle to get a little stiffer, but the brakes still don't feel right. So my service manager said that the rear brakes prolly need to be adjusted. So I racked the car back up and you can take the rear wheels and spin them freely, very eaisly. I know they are not supposed to spin that easy. So I took the dust cover off and came to take the drum off, but I didn't have a socket large enough to fit on that nut. Then I came here and did some searching and found out that the rear brakes are self adjusting. How exactly do you get them to "self adjust"?? I tried pulling the ebrake a bunch of times, driving in reverse, pulling the ebrake while driving, so forth and so on and they still feel the same. Is there an adjustment screw behind the drums?? What size is that bolt to get them off? Any help would be appreicated. Thanks.
