What's the secret to taking up the slack in that lousy, so-called, automatic adjuster mechanism? I've gone through the Helm manual method of pushing forward on the cable, while someone stomps the pedal. Thought for a while that I had it, but it didn't pan out. The pads are hardly worn at all. These things are supposed to hold your truck, plus a trailer, facing up a hill, but I'll bet mine wouldn't hold the empty truck, right now!
