Chevrolet Sonic Repair Manual: Master Cylinder Reservoir Filling
Warning:
Refer to Brake Fluid Irritant Warning.
Caution:
Refer to Brake Fluid Effects on Paint and Electrical Components Caution.
- Visually inspect the brake fluid level through the brake master cylinder reservoir.
- If the brake fluid level is at or below the half-full point during routine fluid checks, the brake system should be inspected for wear and possible brake fluid leaks.
- If the brake fluid level is at or below the half-full point during routine fluid checks, and an inspection of the brake system did not reveal wear or brake fluid leaks, the brake fluid may be topped-off up to the maximum-fill level.
- If brake system service was just completed, the brake fluid may be topped-off up to the maximum-fill level.
- If the brake fluid level is above the half-full point, adding brake fluid is not recommended under normal conditions.
- If brake fluid is to be added to the master cylinder reservoir, clean the outside of the reservoir on and around the reservoir cap prior to removing the cap and diaphragm. Use only GM approved brake fluid from a clean, sealed brake fluid container.
