Bleeding the brakes by pumping the brake pedal repeatedly has one big disadvantage: the piston inside the master cylinder can travel past the slight lip that has formed with normal usage, possibly damaging the seal. This does not happen with a pressure system such as the Gunson Eezibleed as the master cylinder piston will not be moving. If new components have been fitted, or the fluid is contaminated, the system must be bled. Manufacturers recommend changing brake fluid every two years.So the first task if to check the condition of the existing brake fluid - this is easily carried out with... Read More

Colortune is a unique mixture setting device and a detector of other mixture related problems. It is a spark plug, which runs the engine like any normal spark plug, but because it has a glass insulator, it allows the colour of the combustion flame inside the cylinder to show through andindicate the strength of the mixture.How Colortune works:Combustion at its most efficient produces a clear blue flame, various colours result in inefficient mixtures. Inside an internal combustion engine those same colours are present though not normally seen. With Colortune fitted in place of a spark plug, the... Read More
