Nissan Sentra Service Manual: Brake fluid
Inspection
BRAKE FLUID LEVEL
- Make sure that the brake fluid level in the reservoir tank is between the MAX and MIN lines.
- Visually check around the reservoir tank for brake fluid leakage.
- If the brake fluid level is excessively low, check the brake system for leakage.
- If brake warning lamp remains illuminated after parking brake pedal is released, check the brake system for brake fluid leakage.
BRAKE LINE
- Check brake line (tubes and hoses) for cracks, deterioration or other damage. Replace any damaged parts.
- Check for brake fluid leakage by depressing brake pedal under a force of 785 N (80 kg-f, 177 lb-ft) for approximately 5 seconds while engine is running.
CAUTION:
If brake fluid leakage occurs around joints, retighten or replace damaged parts as necessary.
