![]() The primary shoe faces the front of the vehicle and usually has a shorter lining and the secondary faces the rear. Notice where the lining is fastened to the shoe before installing. The primary and secondary linings are often made from different materials and it is important not to mix up the two. As brake shoe temperatures increase the overall performance and effectiveness of the shoes will suffer. In fact a brake shoe can easily reach 450° F from a 55 MPH stop. This friction is transformed energy and produces great heat. It is the lining of the primary and secondary shoes coming into contact with the rotating drum that causes the friction necessary to bring the vehicle to a stop. Brake shoe anchors are attached to the backing plate and allow for the brake shoes to come into full contact with the drum while providing an anchor for the momentum. This forward motion wedges the shoe into the drum and transfers to the secondary shoe which is also forced into the drum with help from the wheel cylinders piston. The rotating brake drum then drags the primary brake shoe along with it in its forward rotation. Chevelle coupes had a cushion in location 4 as well, but the convertible has an upper and lower bushing with a bolt. When the brakes are applied the primary shoe is forced into contact with the brake drum by the piston of the wheel cylinder. that statement could cause some debate in and among itself and get real political. When the brakes are applied it is that cohesive part that brutally grabs at the road - an action that forces this wheel/drum/axle-shaft assembly to violently leap relatively rearward - pressing the inner surface of the brake drum most-so upon the forward-facing shoe."Įrgo: The proper place for the larger shoe is forward.īUT.everywhere you look and read its the opposite. "Remember: Bolted together as one cohesive part, are the rear-wheel, brake-drum and axle-shaft. Oh.and yes "they cant put it on the internet if its not true" applies here as well. I am going to open a can of worms here but hey its all good in the TC hood right? Or maybe mr Bendix had wrong to begin with.nah that would be blastphamy Maybe its a "common held belief" that larger shoes goes to back because thats what been done for generations and been passed down by us to our kids and co workers. ![]() However the VW bug I restored as my first cazr had equal length shoes? My El Camino when we bought it had the large shoe facing forward before we rebuilt it. later 68's and all 69 bezels have that lip 'up' and exposed. The older rarer 68 design also has the upper 'lip' of the bezel where it touches the header panel, rolled under. 68 bezels, that ridge is farther in- about 3/4'-1' inch in. We are restoring a 56 Chevy that has all four drum brakes installed with larger shoe facing front of vehicle. True 69's will have a slight embossing ridge running around the inside of bezel- about 1/4' from the outside edge. Maybe a dumb question but.Which is proper position? Over the years I have seen and worked at countless dealerships that have installed the larger shoe on the front and in the rear position as well and that swear it was correct. I replied to another thread in brakes with this but i believe it applies to restorations as well-what do ya think?
