AMMCO's brake lathes are versatile, easy-to-use and durable. In fact there are more AMMCO brake lathes in service than all other brands put together. And quality accessories are what keep the lathes going. The outboard-mounted brake drums now used on class 7 and 8 tractor and trailer brake systems can weigh up to 120 lbs. and it's tough to get a good grip on them when removing or installing. A costly back injury and a workman's comp. claim can result! Now there's a better way. Just roll the No. 5017 drum dolly into position flip the metal hook and roll it away. Reinstalling drums is just as easy. Roll the dolly into place, line up the studs with the holes in the drum and push it into place. Handles all popular 15in. and 16 1/2in. drums. A 5in. height adjustment telescoping handle (adjusts from 37in to 55in) ball bearing wheels pneumatic tires and rugged steel construction are just a few of the features of this American-made product.

More complicated type of brake is a drum brake. The concept here is simple. Two semicircular brake shoes sit inside a spinning drum which is attached to the wheel. When you apply the brakes, the shoes are expanded outwards to press against the inside of the drum. This creates friction, which creates heat, which transfers kinetic energy, which slows you down. The example below shows a simple model. The actuator in this case is the blue elliptical object. As that is twisted, it forces against the brake shoes and in turn forces them to expand outwards. The return spring is what pulls the shoes back away from the surface of the brake drum when the brakes are released. See the later section for more information on actuator types. height adjustment telescoping handle (adjusts from 37in to 55in) ball bearing wheels pneumatic tires and rugged steel construction are just a few of the features of this American-made product.
