Re: How do adjust those rear Cadillac calipers? Again?
Remember if you increase the cable travel for the same pedal travel, you decrease the leverage.
I used a 12" crescent on the levers on the calipers and ratcheted them until I got the pads adjusted up.
New pads might help or use some sandpaper to rough up the existing ones to remove any glaze and increase the friction just before you go to have it inspected.
Also grease the bolts that hold the calipers so they slide easily. You need to clamp the disc between the inner and outer pad. If the calipers don't slide on the guide pins, you're just pushing the inner pad against the disc. The outer is putting little or no pressure on the disc.
Are you sure you don't have any binding of the cables in the sheath. If the inner cable moves easily, oil it. If it doesn't replace it.
Once you've got everything moving free and adjusted up, adjust at the cable splitter until you're e-brake is as tight as you can get it. Press down on the e-brake pedal and your brake should hold. Now release the e-brake pedal and loosen the nut at the splitter a bit so the rear brakes don't drag or only drag a little.
Recheck to make sure the e-brake holds. If not, tighten the nut at the splitter.
Remember, you are adjusting to pass the inspection. Once you do, back the adjustment off at the splitter until there is no rear brake drag.
