Default Help! Brakes!

New to this thing. At 72, I thought I could learn something new. Maybe not.

Took all four wheels assemblies off including backing plates. Cleaned everything. Sent shoes out for relining.

Fronts back together. Drums do not fit over new linings. Adjusting wedge all the way out.

What next?

Were the ends of the linings sanded down on an angle at each end?

Did you have the drums trued and have the relined shoes arced to fit each drum?

The adjusting wedge is on one end of the brake shoes, and the operating wedge on the other.

There is no telling how the brakes may have been adjusted in the past to compensate for brake pad wear, and it is possible that the brake rods were adjusted (shortened) to adjust for brake wear.

Remove the clevis pin on the brake operating lever and be certain that the operating wedge is not holding the brake shoes apart.

Make certain that the brake shoes are "centered", and the drum should fit.
There is more to rebuilding the model A brake system than new linings.

The brake tracks usually need to be built up with weld or replaced . There will be a dip in the tracks where they have been worn . The worn spot on the tracks will allow the brake shoe to drop out of center alignment . If the shoes are very far out of center the brake drums won't fit over the shoes in such a way that will allow installation of the brake drum .

Thanks for the help. I had put one roller pin in upside down. The cotter pin was interfering.

Make sure that you install the roller pins correctly with the cotter pins inboard.

The photo with the yellow backing plate has the roller pins installed incorrectly, and could rub against the brake drum.

The 2nd photo has the correct installation of the roller pins.

Did you reline with woven lining or bonded lining? Bonded can sometimes be thicker, depending on the knowledge of the reliner.
