Brake fluid and pads (Chevrolet Tahoe 1)

Brake fluid

The picture shows the brake master cylinder with a reservoir. It is filled with DDT-3 brake fluid. There are only two reasons why the fluid level in the reservoir can drop. The first is that the level drops as a result of worn out gaskets. When new gaskets are installed, the fluid level rises. The second reason is that fluid is leaking from the brake system. If this is the case, you should repair the brake system, because sooner or later the brakes will not work properly or at all.



So it is not a good idea to add fluid. Adding fluid will not fix the leak. Add fluid when you repair the brake system.

Checking the brake fluid level

You can check it without removing the cap. Just look at the brake fluid reservoir. The fluid level should be above the MIN mark. If it is not, find the cause of the fluid leak. After the work with the brake hydraulic system is done, add fluid to the level above MIN and below the top of the window.

What to add

Use only DOT-3 brake fluid such as Delco Supremell (GM Part N12377967). Use only sealed container.

Always clean the lid and reservoir before removing the lid.

Brake wear

Your vehicle has front disc brakes and rear drum brakes.

Disc brake pads have built-in wear indicators that emit a high-pitched warning sound when the pads are worn and new ones are needed. The sound appears and is heard all the time while the car is moving (except when you press the pedal firmly).

Some driving conditions or weather may cause brake squeal when the brakes are new. This is normal.
Properly fitted lug nuts are essential to prevent brake pulsation. When balancing wheels, check brake pads for wear.

The rear cylinder brakes do not have indicators, but if you hear a rubbing noise from the rear brakes, check the pads, and the drums should be removed and inspected every time you remove the wheels for replacement or balancing.

When you change the front brake pads, check1 the rear brakes too.

Brake pedal failure

If the brake pedal does not return to its normal height or sinks when pressed, contact a service station.
