1940 Brake Adjustment
Posted by Joe Santana On 2012/8/12 13:06:02
I tried to adjust the brakes, starting with the right front wheel. I turned the start the wrong way, then turned it back until the wheel locked, then backed it off until the wheel turned freely, per manual.
But when I went to measure the distance between the brake shoe and drum, should be .015 in., it was like 3/16 in. ... like .18. Puzzled, but thinking it has something to do with the eccentric, measured the clearance on the left front wheel, since I hadn't touched that.
I rotated the inspection slot to the 5 o'clock position and stuck the .015 feeler gauge in. It came out greasy black. I hadn't touched the left wheel. How could it be messed up?
I decided to pull the hub of the right wheel and have a look. Everything looks right, except the adjustment is tightened almost all the way, sucking the bottom of the shoes in toward each other.
I decided to look at the left front wheel. There's grease everywhere.
About 4 months ago, my son helped me pack the wheel bearings. He's knowledgeable mechanically, but he lives an hour away. The brakes have been fine since then, until only recently they felt like they needed adjusting.
Perhaps I only needed to adjust the pedal.
In applying the brakes, they never pulled to the right or left.
I'm going to clean off the left wheel.
Look at it as an investment. It took me 2 weeks to learn to do a basic tune-up, but I can do the entire thing now from replacing plugs and assembling/setting points, to timing. I won't have to ask about that issue again, knock on wood.
