![]() ![]() Oh by the way.next time you are grocery shopping at Wal-Mart, look at the food labels carefully. ![]() There are no environmental restrictions or quality control on products from China!! You pay the price for products that are the "same" but however "slightly different." Look at the ST tires coming from China!! Many products we are using now are of poor quality and downright dangerous. So beware of the parts you are using to service not only brakes but practically anything!! All companies have contracted to China in the interest of corporate profit. This was very frustrating to us because we are both experienced mechanics. We will purchase Dexter assemblies and try all of this again. We don't really know which of these problems or in combination with one another caused these brakes to become dangerously hot but we do know the supplier agreed to take them back and refund the money after we discussed all the differences we noticed and the problems they caused. The actuator magnet ridding higher and thus in an area on the drum armature surface which was not burnished or previously used by the old magnet could have caused the actuator to drag a little harder and thus pull the brakes on even though no electic was applied. These holes are large, probably 5/8 inch and have sharp edges. The actuator magnet may have also gotten movement from ridding over the holes in the drum where the lug bolts are pressed in. Upon closer examination, the actuator magnet rode at least 1/4 inch higher on the drum surface and this possibly could allow the actuator arm to get hung up on top of the front brake shoe causing it not to relax when in the non braking mode. To make a long story short as they say.the new brakes we installed (made in China) were different. ![]() DEXTURE AXLE ACTUATOR ARM PLUSPlus we had some braking abilitiy from the front axle. It had to be mechanical because the front axle remained totally cool all of the time. So the brakes had to be coming on somehow during our test run. The drums were cool to the touch when we arrived home. To get back home we backed off on the brake shoe adjustment as far as it would go which totally disabled the brakes on this problematic rear axle. We tested everything, current to the brakes, voltage readings and everything.perfect.Īfer another test run with the same results we unplugged the electric connector to the truck.brakes continued to get really hot. Our examination showed nothing, the wheels spun easily, no rubbing or friction was noticable. Wow, what could have gone wrong? We let them cool and headed back. ![]() After driving less than 10 miles we stopped to check everything out and to our astonishment the drums were scalding hot!! When we poured a small amount of water on the drum we got steam. After installing them and doing the wiring and making a slight adjustment to the shoes we went out for a short test run to burnish in the new pads. This includes the plate, shoes, actuator magnet and springs all built together. He purchased the entire brake cluster assemblies for both sides. I was involved in my friends brake replacement job and we became totally frustrated with an ongoing problem. Topic: MUST KNOW information if you service electric brakes!
