Hey guys, just wondering how to fix this issue. I tighten up the brake band and drive around the block a couple times and it already needs to be tightened again. I'd have to cram the pedal against the floor boards to get it to stop decently well after driving it for a little while. It's a 1924 Touring by the way. I eventually want to get a set of Sure Stop brakes for it, but I can't really afford them yet. What can I do to fix this?
First what kind of band material? How long have the bands been in the car?
If it's new Kevlar, then they will need several adjustments then will set in and require infrequent adjustments.
Even cotton need the same break in but more frequent adjustments.
Jared, how far was the pedal height in conjunction with the floor before you went for your drive? Like others have said, need more info, but I'm confident all the smart folks here will be able to figure it out for you.
The pedal sits about 3-3/4" from the floor. Don't know what kind of linings they are, but I would assume they're cotton. They're from when my grandfather restored the car in 1986. Hasn't been driven a whole lot since then, just once a year in an annual parade in my town. Would like to start driving it more though!
Jared, i should have phrased the question better. When fully depressed how far is the pedal above the floor? Is it possible for you to remove the cover on the hogs head and take some pics? If you can, than we could probably get a better idea of the linings you have and see if anything seems to be out of sort.
Make sure you have the washer with good humps and a good nut to sit on the humps, otherwise, everytime you apply the brakes, the nut will loosen a bit. There's other things such as a band lining coming apart.
Hate to say it, but it could be a cracked drum...
Look very carefully.
My brake needs adjusting after a days driving. Suspect the drum is cracked but there is not a hope of fixing that. Will keep driving and replacing my brake bands for the foreseeable future.
Yours sounds slightly worse. Have your bands been under water? That can make them rot and wear faster.
Do you have the "Transmission band adjusting nut washers" in place to keep the nuts from backing off? Langs part number 3415.
I'm not sure how long you have been driving but, It really helps to drive it like a( MODEL T). If you ever find yourself pushing hard on the brake peddle to stop, you are pushing the limit. Let off, anticipate the stops drive it like it doesen't have brakes, and then maybe it will actually stop when required. I am finally learning some of the tricks to longevity. Hopefully, you don't have mechanical problems, but leaning on the brakes will create problems. Traffic lights, seems like our brakes worst nightmare. Like the guys said, there is a brake-in period, light pressure during this time will also help to longevity. You may have even more experience driving than me, but this may help someone. Happy trails.
John Warren makes a great point. You can ruin a low band (or a reverse band) if you rev the engine to the moon and then slowly, gingerly apply the pedal on every start.
Listen to the engine during this drive. The engine is at idle or slightly above when the low pedal is depressed swiftly with a minimum of band slippage:
