There is also a star wheel adjuster for the brake shoes inside the rotor. You can access this by taking off the rear wheels and turning the rotor until one of the holes is about straight down. It can be adjusted using a standard screwdriver.
I went through the whole adjustment procedure and got my parking brake working great, it would hold my car on any hill while in neutral, but when I was going at any speed less than 15 MPH they would squeak like crazy. So I set it back how it was originally and it won't hold my car.
So basically if you can't get it adjusted right using the nuts on the cables, it's probably not worth digging into to much. Pretty much every 65-87 Corvette has a poorly working parking brake.
I agree, go for the adjustment at the wheels first. The only problem you could have with that is if the rotors have been removed/reinstalled and not had the adjusting holes (one on the rotor, one on the hub) lined up. If that is the case, you won't be able to get to the star wheel without pulling the rotor and aligning the holes correctly. Anyway, pick up as much adjustment there and use the cable turnbuckle for a fine-tuning adjustment. My e-brake holds the car solid in drive and reverse :yesnod:
Or, if the star wheel adjustment is hard or full, the cable can be adjusted
with a 1/2" flare wrench (a plain open end will do.)
Just slide under there and turn the front nut to give you some room, then turn the
rear nut to tighten up the cable. Make sure the two nuts tighten together...
Just finished doing it.
Are ther any on line tutorials on the Ebrakes? As common a problem as this is someone must have put something together on it. I have got to believe ther are one or 2 bugs which are tripping us up on this
