ABSTRACT
A tricycle is a three-wheel vehicle used in conveying goods and humans from one place to another especially is the rural and farm area absorbing energy from the moving systems, drakes are generally applied to a rotating axle or wheels but may also take another form such as a moving fluid. Brake pedals are irregular in shape in at least the direction. Casting of the brake pedal is to reduce the weight, the sand casting is a process by which sand is use to prepare the mould. The pattern is made with a manna wood. Aluminiun was used to east the part. During the casting of the product to increase the strength of the aluminium, silicon was added to it during melting. Specimen were also produced which was latter machined and due for tensile test.
