Not sure how to explain, brakes still work fine.Left parking brakes halfway down drove about 30 minutes What damage will thisdo?Hey Brenda, we've all done it so don't feel bad. The rear brake pads / shoes are manually gripped to the brake rotor or drum, depending on if ya have rear disc brakes or drum and thye may have got a little heate up and possibly %26quot;Glazed%26quot; meaning a mechanic could remove them and with some sandpaperrough up your brake shoeor pad and do the same to your rotor / drum an if thats required then just get new brake pads / shoes installed. Since everything still stops OK, then I'd say you are OKLeft parking brakes halfway down drove about 30 minutes What damage will thisdo?need to check brakes shoes, pads, rotors, drums
