Chevrolet Sonic Owner's Manual: Brake Fluid
The brake/clutch master cylinder reservoir is filled with DOT 3 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview for the location of the reservoir.
There are only two reasons why the fluid level in the reservoir might go down:
- The fluid level goes down because of normal brake lining wear. When new linings are installed, the fluid level goes back up.
- A fluid leak in the brake/clutch hydraulic system can also cause a low fluid level. Have the brake/ clutch hydraulic system fixed, since a leak means that sooner or later the brakes and/or clutch will not work well.
Do not top off the brake/clutch fluid. Adding fluid does not correct a leak. If fluid is added when the linings are worn, there will be too much fluid when new brake linings are installed. Add or remove brake fluid, as necessary, only when work is done on the brake/clutch hydraulic system.
Warning
If too much brake fluid is added, it can spill on the engine and burn, if the engine is hot enough. You or others could be burned, and the vehicle could be damaged. Add brake fluid only when work is done on the brake/clutch hydraulic system.
When the brake/clutch fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light.
