Re: [FWDLK] Contour Grinding Brake Shoes



Start with basics. The shoe measures X by X for so many square inches. Ideally, you want/need ALL those little squares contacting the drum, hence contour grinding. This matches the shoe radius to the precise shape/radius of the drum, when applied. If not done, you may end up with a band 1 or 2" wide being the only point of contact.

The few panic stops will glaze any high spots on the shoe, where they actually touched the drum. It may take quite a few stops to get the shoes shape close, if they ever do. Look at the shoes and see if some of the lining has ever touched the drum after some use. Often, the shoe can be 15% or more used before all the material is touching. Meanwhile as others mentioned, your stopping ain't up to snuff, not good.

OK, let's say I didn't contour grind the brake shoes to fit the drums. Would a few 'panic stops' be enough to contour the shoes to the drums ? How much
material is actually removed from the center of the shoe to get it to
conform to the drum ?
