Better for your Brakes & Clutch. 3 sizes: 250ml, 500ml & 1 litre. Automec Silicone Brake & Clutch Fluid performs better than glycol based fluids on three main counts: 1] It does not absorb moisture & so stops corrosion & associated problems like sticking calipers, etc. 2] Because it does not absorb moisture it has an indefinite life & does not require regular fluid changes. 3] It is non-toxic & virtually inert, meaning it is harmless to you, your car & your paintwork. Meets D.O.T. Safety Standards in the UK, US, & Europe. NOTE: Not suitable for replacing mineral oil fluids used in many Citroen & Rolls Royce vehicles.
