How to Flush Brake Fluid On Suburban

Brake fluid is a vital component of your car’s braking system. It helps to slow or stop the vehicle, and it should be flushed and replaced as needed. This guide will show you how to flush brake fluid on a suburban.

What is brake fluid?

Brake fluid is a type of hydraulic fluid used in hydraulic brakes to provide a smooth, consistent stopping power. Brake fluid is typically vented to the atmosphere through a breather hose when the brake system is not in use. When the brake pedal is depressed, the hydraulic pressure causes the brake pads to come into contact with the rotor, which in turn causes the brake fluid to squirt from the brake line and onto the rotor. This creates a friction between the pad and rotor that stops the car.
How do I flush my brake system?
To flush your brake system, you will need to remove the calipers and bleeder valve. Next, remove the cap on the master cylinder reservoir and release all of the brake fluid. Pump enough fluid into the reservoir until it reaches the fill line on top (this should be about four or five cups). Replace the cap and tighten it securely. Replace the calipers and bleeder valve, making sure they are seated properly before re-installing them on the axle. Finally, replace any Brake Line Hose connections that may have been disconnected.
When you’re done, replace all of the screws that hold together your parking brake cable bracket and adjust if necessary. Recon

1) Park the suburban in a safe location so you can access all of the brake fluid lines.
2) Remove the master cylinder cap and unscrew the reservoir.
3) Remove the brake fluid hose from the reservoir and disconnect the nipple at the end of it.
4) Disconnect the supply line from the master cylinder and pour about 1 cup of brake fluid into each of the three lines leading from the reservoir.
5) Reconnect all of the hoses and cap everything back up.
6) Drive your suburban around for a few minutes to make sure everything is operating normally. If not, continue with step 7.

When should you replace brake fluid?

The answer is, “it depends.” Brake fluid must be replaced every 7 to 10 years, depending on the type and severity of use. The vehicle’s brake system is composed of several parts: the master cylinder, calipers, pads, and rotors. The brake fluid helps to reduce friction between these parts and makes it possible to stop the car quickly.


If you’re experiencing problems with your brake fluid, there are a few things you can do to try and fix the problem. The first thing is to flush the system with clean water. Next, you may want to replace any of the brake pads or calipers if they are worn down too much. Finally, you may need to flush and bleed the system several times in order to get all of the old brake fluid out.
