Nissan Maxima 1993-1998 Repair Guide

Brake and Clutch Master Cylinder



When adding or changing the fluid in the systems, use a quality brake fluid of the DOT 3 specifications.

Never reuse old brake fluid.


See Figures 1, 2 and 3

The brake and clutch master cylinders are located under the hood, in the left rear section of the engine compartment. They are made of translucent plastic so the levels may be checked without removing the tops. The fluid level in both reservoirs should be checked at least every 15,000 miles. The fluid level should be maintained at the upper most mark on the side of the reservoir. Any sudden decrease in the level indicates a possible leak in the system and should be checked out immediately.

When making additions of brake fluid, use only fresh, uncontaminated brake fluid meeting or exceeding DOT 3 standards. Be careful not to spill any brake fluid on painted surfaces, as it eats 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.
