Piston Slap: Of Antique Trucks and Rebuilt Brakes

TJ writes:

My New Year’s resolution this year was to get my grandfather’s 1979 Chevy C10 running and driving again. It’s been parked in the garage since I drove it in there when my wife and I moved into our house in spring 2012. I stopped driving it because the transmission needed (another) rebuild and I didn’t have the time or money then. I’ve managed to get it running (full carb cleaning and new sending unit in the tank) and it will idle after some urging.

Now the next issue: I decided to check the brakes by jacking up first one end then the other and spinning the tires, then having someone step on the brakes (my 4 year old loved it). 3 out of 4 wheels spin, but the brakes don’t stop more spinning. The front passenger is stuck. I was able to get the rotor to turn some with a breaker bar. I could also hear some dragging in the rear passenger drum, but I was still able to turn it by hand. The pedal has some firmness, but not a lot and it doesn’t get hard after the engine is off (have to check the booster once I get the brakes working).

My first thought is to replace the front calipers and rotors (rotors probably need it anyway) and wheel bearings, since the rotors will be off. I’m not above rebuilding the rear drums also. Before I drop a bunch of money on parts, I thought I’d reach out for advice.

  • Dale Quelle surprise.
  • 3SpeedAutomatic Nice looking, but IIRC, there was an issue with these engines where a knock would develop. That may account for the very low milage. 🚗🚗🚗
  • Redapple2 Used to watch F 1 a great deal. Now? F1 Random thoughts:1 Silly rules bug me. Must use 2 types of tire. Cant refuel. Drag reduction can only be used in certain areas of the track and only if you are so close to the car in front.2 Passing is rare. Pole sitter wins a high % of the time.3 A new team can only start in F1 if they get the blessing of the overlords. Evil gm Vampire was barred. How about this. Anybody with a car that meets the construction rules can try. If your speed qualifies and you pay the entry fee. You re in. So is anybody else. 4 I tune in for Martin Brundle's grid walk. In my life, it s must see tv. But he is often bumped or cancelled. Grid walk takes place 1 out of 3 or 4 races.5 So, because of this utter bull sheet and other points, I ve migrated to IMSA and MotoGP. I might catch a summary on the youtube.
  • Redapple2 I retract my comments and apologize.
  • Flashindapan I always thought these look nice. I was working at a Land Rover dealership at the time the LR3 came out and we were all impressed how much better it was then the Discovery in just about every measurable way.
