I have bought a Gas Gas EC 300 year 2000 and am in the process of getting it back a fit for use. I am new to mechanics and need help with the rear brake that i have just serviced. There are two thin metal plates. Each a different shape, that somehow sit on the bake of the brake pads. I cant see how they should be refitted in order to replace the pads. Can someone help explain / send a picture or tell me where i can get hold of a workshop type manual that would have a diagram to assist. Any help for a newbie would be much appreciated. ta. Also are there any Gas Gas riders in the surrey / sussex / hants area that would like to meet for green laning. ??
