Morris Brake Fluid is made from high molecular weight polyalkylene glycol ethers and polyalkylene glycol ether borates, to give a high boiling point fluid of DOT 4 quality. The product is blended with special additives that prevent fluid oxidation, rust and the swelling of the piston seals used in conventional brake systems. Morris Brake Fluid has been manufactured to exceed vehicle manufacturers standards and has been designed for use at high temperatures under the most severe conditions. This fluid is compatible with all other non-mineral brake fluids manufactured to the same specifications.
