I am in the process of replacing the handbrake quadrant, the teeth are worn. I have the four rivet type and am having a hell of a time getting the rivets out!! Is the method it is attached necessary? Does it need to be mounted as if it has to hold up the Empire State building or is it a victim of over engineering?
I plan on using bolts for the replacement; I donít see a problem with that other than it not being original. At this point I am interest in safety functionality and reliability after that comes appearance.
You have to remember that a bolt cost vs rivet cost was enough of a difference to make Ford go with the rivet. Besides they were riveting everything onto the chassis anyway, using a bolt there would be an extra process step, meaning somebody would have to crank nuts onto those bolts...it would just be too costly in production time.
Mike, bolts are fine here.
Mike, I used these ribbed neck bolts from McMaster-Carr. The diameter of the ribbed section is large enough that it fit tightly in the holes in the quadrant and frame so there was no slop like you would get with regular 1/4" bolts. When I installed them, they were tight enough that they drew in snugly as I tightened the nuts and they had no tendency to spin in the holes.
I used lock washers and Loctite just because.
If you drill out the center of the rivet, leaving only a shell, and chisel off the head, the rivet will come right out.
Brian, the ribbed bolt is a great idea!!
I just had the same issue with my '27's battery rack. I couldn't get a drill on the rivets because any power drill that I could find was too large for the confined space. T's are small! I eventually went with my Dremel power tool and a small grinding attachment in it's chuck. The battery rack rivets are 3/8" so the quadrants' 1/4" rivets shouldn't be too bad to grind the heads off. I'm too lazy to try to find those ribbed carriage bolts - I would use grade five or eight bolts with locknuts. I can get them at the local hardware store. The quadrant won't go anywhere. The bolt takes the load, the nut only holds the bolt in place, so you don't need to drive yourself crazy looking for grade five or eight locknuts.
I've replaced them, and have used rivets, but if your car is together, it's difficult to do, therefore, if you aren't out to win any prizes, then bolts will work just fine.
Use bolts. It crazy to use rivets. If you ever want to sharpen your ratchet again you will HAVE to take it apart and as the guys say above rivets are a bear to get out once the body is on. Any ratchet will wear out if you keep your T long enough and drive it for more than across town once a month for ice cream!
The Correct Police are going to get you guys.
Unless you are going to an under body and chassis car show and expect to win a prize bolts will hold it. But, for safety's sake, if it were mine, I would not use lockwashers, but either use castle nuts with cotter pins, or peen the end of the bolt so the nut won't come off.
Remember that lever is what keeps the car from running over you when you crank start. Also can keep it from rolling downhill when parked and keeps it in neutral when using the reverse or low when in a parade. Due to the vibration of the engine, it could cause the bolts to come out. So be safe.
Lol Steve, I think those rivet/bolt things are genius. All the look of a rivet and none of the work!
