Honda Civic/CRX/del Sol 1984-1995 Repair Guide

Clutch Master Cylinder


Honda Civics beginning with 1992 models are equipped with a hydraulic clutch actuator which eliminates the need for periodic clutch adjustments. The system works on the same principle as hydraulic brakes. Previous year Civics use a conventional cable.


Use only fresh DOT 3 or DOT 4 specification brake fluid from a sealed container. If you are unsure of the condition of the fluid (whether or not it has been tightly sealed), use new fluid rather than taking a chance of introducing moisture into the system.

Brake fluid is a very effective paint remover. If any spills on a painted surface, wash it off without delay.


The fluid level should be between the MIN and MAX marks on the side of the reservoir. Low fluid level could mean that there is a leak in the clutch system. Unlike brake wear, clutch wear will not proportionally lower the fluid level in the reservoir.

When adding brake fluid, the following precautions should be observed:

Use only recommended brake fluid: DOT 3 or DOT 4; SAE J 1703b HD type.
Never reuse brake fluid and never use fluid that is dirty, cloudy or has air bubbles.
Store brake fluid in a clean dry place in the original container. Cap tightly and do not puncture a breather hole in the container.
Carefully remove any dirt from around the master cylinder reservoir cap before opening.
Take special care not to spill the fluid. The painted surface of the vehicle will be damaged by brake fluid.
