Installation Notes and Tips

Verify chassis and application notes before installation, especially on 1993 Honda Civic del Sol models with chassis-specific coverage. Confirm the vehicle is configured without a master cylinder where required by the fitment listing. Inspect the vacuum supply, check valve, and master cylinder interface before installing the replacement booster to avoid repeat brake assist concerns.
