Where is the brake fluid in a 2017 Chevy Cruze?
In a 2017 Chevrolet Cruze, brake fluid is stored in a dedicated reservoir in the engine bay. The fluid is accessed from the top of the brake master cylinder, near the brake booster, on the driver's side of the engine compartment.
Location in the engine bay
The brake fluid reservoir is a translucent plastic bottle mounted on top of the master cylinder, which sits next to the brake booster at the back of the engine bay on the driver's side. The cap is labeled BRAKE FLUID and the bottle has MIN and MAX level marks. Access is easiest with the engine cool and the hood open.
Fluid type and safety
Check the reservoir cap for the exact specification. The Cruze commonly uses DOT 3 brake fluid; if the cap specifies DOT 4, use DOT 4 instead. Never mix different types. Always ensure the engine is cool before opening to avoid fluid splashes and burns.
How to check the brake fluid level
Use these steps to inspect the level and condition of the brake fluid:
- Park on a level surface and let the engine cool to avoid contact with hot components.
- Wipe clean around the reservoir cap, then carefully remove the cap.
- Inspect the fluid level against the MIN and MAX marks on the side of the bottle.
- If the level is below the MIN line, add the correct DOT brake fluid slowly up to the MAX line.
- Reinstall the cap securely and wipe away any spilled fluid from nearby surfaces.
Regular checks help prevent air in the braking system and maintain pedal feel. If the level frequently drops, there may be a leak or worn components and you should have the braking system inspected by a mechanic.
Top-up and maintenance tips
When topping up or replacing brake fluid, follow these precautions:
- Only use the brake fluid type recommended on the reservoir cap or owner's manual (usually DOT 3; DOT 4 if specified).
- Do not mix different types of fluids and never top up with other fluids (power steering fluid, coolant, etc.).
- Keep the reservoir clean; avoid letting dirt fall into the opening; wipe the outside afterward.
Always consult the owner's manual for the exact fluid specification and maintenance schedule. If you notice a persistent drop in fluid level or signs of leaks, seek service promptly.
Summary: The brake fluid reservoir in a 2017 Cruze sits atop the brake master cylinder near the brake booster on the driver's side of the engine bay. Confirm the required DOT fluid on the cap, check the level monthly, and top up to the MAX line with care. If you see dark fluid, leaks, or frequent level changes, have the braking system inspected.
