Master Cylinder Reservoir Check
Do not use shock absorber fluid or any other fluid which contains mineral oil. Do not use container which has been used for mineral oil or which is wet from water. Mineral oil will cause swelling and distortion of rubber parts in hydraulic brake system and water will mix with brake fluid, lowering fluid boiling point. Keep all fluid containers capped to prevent contamination.
Fluid to fill reservoir with is indicated on reservoir cap of that vehicle with embossed letters or in owner’s manual supplied with it.
Add fluid up to MAX line.
