FLUID RECOMMENDATIONS AND LEVEL CHECK
The brake master cylinder is located under the hood, in the left rear section of the engine compartment. It is divided into two sections (reservoirs) and the fluid must be kept within 1 / 4 in. of the top edge of both reservoirs. Some reservoirs will have minimum or maximum fluid level marks on an outer side wall in order to help determine if the fluid is at a proper level. The level should be checked at least every 7,500 miles.
Any sudden decrease in the level of fluid indicates a possible leak in the system and should be checked immediately.
To check the fluid level on most vehicles covered by this guide, you may peer through the side wall of the reservoir and observe the level in relation to the markings. If the reservoir is opaque, simply pry off the retaining bar or unsnap the cover, then lift off the top cover of the master cylinder, taking care not to allow any fluid to drip on painted surfaces. When making additions of brake fluid, use only fresh, uncontaminated brake fluid which meets or exceeds DOT-3 standards. Be careful not to spill any brake fluid on painted surfaces, as it will quickly eat the paint. Do not allow the brake fluid container or the master cylinder reservoir to remain open any longer than necessary; brake fluid absorbs moisture from the air, reducing its effectiveness and causing corrosion in the lines.
