Hi. I read the service manual and it says to turn the adjustor until the rotor wont turn and then back it off ten "notches". What exactly is a notch? Do they mean one tooth on the adjustor wheel, or a healthy turn of the wheel or what? Thanks! Brandon

They mean 10 clicks of the star wheel. Each time one of the points turns under the spring. About one notch per full motion of the adjusting tool is about all you're going to get anyway. Sometimes these are hard to feel. Sometimes you can't really tell if the adjuster turned or if the tool slipped. Fortunately, a precise number is not necessary. You just want to be sure the shoes are not in contact with the rotor when the brake is released. If you go too far, you will not be able to get the PB to hold, or it may only hold backing up. -

Re: Need help w. park brake adjustment-67
Brandon, I always go back after a little time has elapsed and re-adjust the parking brake after it has seen some use. I sometimes pull up on the Brake handle at "slow" speed to help seat the shoes. Do not let them get glazed by doing this at a fast speed. It is a bit "Shade Tree" but it does work!Comment

Although not shown in most of the A.I.M.'s, there was an assembly process requirement for a "Parking Brake Burnishing Procedure", where essentially the same thing you're talking about was done during the roll-test process to ensure that the shoes were seated and the system would work as designed when the car was shipped; if the "burnishing procedure" resulted in loss of too many "clicks" of adjustment, the car was tagged for re-adjustment by the roll-tester when he dropped the car off on the final line, and the cable was re-adjusted. This began in 1965, as the parking brake was no longer part of the (drum) service brake system when disc brakes were introduced.Comment
