Overhaul

CAUTION: Do not use denatured alcohol for flushing the brake system or cleaning assemblies where alcohol could be trapped. If denatured alcohol is trapped, it can cause eventual failure of rubber components in the system. Thoroughly dry any parts that have been cleaned with alcohol.

CAUTION: Never allow any petroleum product or mineral oil to contact the inside of a brake hydraulic system. Mineral oil and petroleum products deteriorate the natural rubber seals used in brake hydraulic system. If a brake system becomes contaminated, it must be flushed with clean brake fluid and all rubber seals and flex hoses replaced.

NOTE: Wheel cylinders do not have to be removed for disassembly and inspection.
