The Ford Barn

Having trouble with a 1928 Fordor and looking for help/ideas. Car has all new brakes/bearings just done a little over a year ago. If you back out out of the garage and drive back forward slowly there is a loud "groan" from the right front wheel. No noise when in reverse but consistent when moving forward slowly. If you drive faster there is no noise, however the front brake on that side does squeal a bit.

Jacked up the car and tire moves freely forward and reverse. Checked brake adjustment and pretty much perfect. No noise, no catching or anything. Only when the weight of the car is on the tire and driving slowly in forward.

Will pull the tire and front drum off to see if I can figure out what is going on but hoping for ideas that might help send me down the right path and fix this problem. Thank you in advance.

Hi,

it is possible that the conical wheel bearingscrew has released a little too much and therefore touching the brake drum on the edges of the brake shoes?

It is possible that the shoes are glazed. You may find that if you just rough up the shoes with some 80 grit sand paper, that will cure your noise. Some friction material is harder than other material and has a greater tendency to glaze. The shoes will be shinny if glazed.

While you have the drum off, blow out the brake with compressed air to get rid of the brake dust, while wearing a dust mask.

Werner is talking about setting the nut properly. Tighten it up until there is drag on the bearing than back it off one position of the cotter key. The hub should turn easily without any sign of looseness.

Warning: Technical discussion: The friction of the brake shoes is different when moving and when stationary. The friction when stationary is called stiction. The moving friction is less than the stiction. As the drum starts to move the shoes will let go and slightly move to stick again. The cycle repeats which gives the groan and squeal. Removing the glaze with reduce the stiction.

Forget the brakes, they really don't work. The clutch always sticks, and starts with a jerk. My car grows red hair, and flies through the air. Driving's a blast, a blast from the past.
