Model T Ford Forum: Forum 2017: Noisy Rattling Brake Rods

Anyone have any tips to quiet my rattling brake rods. At certain RPMs the rattle has gotten horrendous.

The noise appears to be coming from the cleaves pinned connection up front where they connect to the brake lever assembly.

The rods connect to the assembly with a fork like adjustment device. I think the noise is coming from to much clearance at the fork. I was thinking about finding a few plastic washers to put between the metal components to take up the space. I have not pulled it apart so the cleaves pins could be worn too. The noise has gotten really bad in the past month.

I'm feeling old today, I have forgotten the technical terms of some of the parts.

Thanks!

Maybe try o-rings instead if washers.

I like that idea!

you might try adjusting the rod about 1/16 inch which will cause you to have to turn the end of the rod a bit to get the pin in place. That will hold things tight. Tighten up the lock nut to keep things in this position.

There are oversize clevis pins available: https://www.modeltford.com/item/2564OS.aspx

I have had rattles with Rocky Mountain rods on a 17 T. I slit an appropriate sized 5" piece of clear plastic tubing and slipped it over the rod. It worked for me.

Very first thing to do is what Roger Karlsson posted - install oversize clevis pins. Ream the holes if necessary but make sure the pins are nice and snug in the holes.

We installed oversize pins on my dad's '17 touring at both ends - at the brake lever yoke and on the backing plate levers on the rear axle.

The above eliminated the rattling. Occasionally oil the pins to keep wear at a minimum.

I added rubber hose around the rods where it goes through the support brackets. Wire tied the hose pieces in place and put grease inside them.

This was a common problem with the Model T especially with the rough roads experienced years ago. My 1919 Touring has period anti-rattle clips/springs on the end of each rod. Maybe someone can post a picture of the clips as they were very common and came in many sizes.

See this thread for brake rod anti-rattlers:

http://www.mtfca.com/discus/messages/118802/173455.html

I've also had a brake handle ant-rattler that was included in a set of brake rod anti-rattlers.

Anti-rattlers come with their own set of problems, such as wearing grooves in the parts to which they are attached.

Like James said. I cut small vacuum lines shorter than the brackets n slipped them over the brake rods and into the brackets. Can't see them in there. My2.

Eric I have a set of those anti rattles on my front end. They came with the T, no clue if they help or not. I see no reason to remove them.

As for slipping a tube over the rod. There is no room in the support bracket for them. I applied a couple layers of a 3M teflon tape I have (not pipe lubricant).

I have not gone for a ride yet. It wI'll be a couple weeks before I order the oversized cleves, as I am prepping an order to test a spare engine my 13 yr old want to get run.

I plan on using a piece of shrink tubing on mine. Doesn't take up much room and with a little grease on them they should last until everything else starts to rattle.

Jason,

It's very easy. Loosen the brake rod support arms that clamp over the radius rods and slide the arms either forward or backward on the radius rod until they put just bit of lateral push or pull on the brake rods. It'll be enough to quiet the rattle but not so much that it binds the rods. Put a little grease there also to compensate for the added rubbing.

I'll have to go back and double check, I recall it being a stamped metal bracket with no adjustments

It's a stamped bracket, yes - but it clamps on the radius rods and by removing the screw you can adjust where it sits on the radius rods - and thus cause a slight sideway pressure on the brake rod. Excellent suggestion, Jerry :-)

It's a good way to use that worn out garden hose. Slip a 6" section over 1 rod where it crosses. 2 clamps to keep it in place. If it rattles at the clevis you have a worn out clevis.
