How to Flush Brake Lines On a 2009 Chevy Colorodo

Brake lines are vital parts of your car’s brake system and every time you brake, the pressure from the brake fluid in the lines forces the calipers to squeeze the pads against the discs. If you don’t flushing your brake lines on a regular basis, this pressure can build up and cause rust and corrosion on the brake lines. In this article, we’ll show you how to do it on a 2009 Chevy Colorado.

Brake Line Flushing Instructions

If you’re having trouble braking on your Chevy Colorado, there is a simple solution: Flush your brake lines.

Here are the steps to flush your brake lines:

1. Park your car in a safe location.
2. Turn off the engine and remove the key from the ignition.
3. Open the front hood of your car.
4.Remove the air filter housing by unscrewing it from the top of the carburetor.
5.Locate and unlatch the Brake Line Flushing Cover (1). Lift it off and set it aside.
6. Locate and unscrew the two bleed screws (2) located on both sides of the master cylinder (3). Do not remove these screws; they will be replaced later.
7. Remove the cap (4) from the master cylinder reservoir (5). Pour about 1 cup of clean brake fluid into reservoir (5); make sure to pour it all into reservoir (5). Replace cap (4) and tighten screw (6).
8. Disconnect both brake lines at their connectors by pulling them out of their fittings. Discard any old brake fluid that remains in lines or reservoirs after flushing them.

Tools Needed

To flush brake lines on a Chevy Colorado, you will need the following tools:

-A few crescent wrenches
-A pipe wrench
-A bucket or a large container
-A cable tie

1. First, remove the wheel hubs from the car. You can do this by removing the bolts that hold them on, or by using a socket wrench. Once they are removed, you can gently pull them off the car. This will make it easier to get to the brake lines.
2. Next, remove the wheel wells. You can do this by loosening the bolts that hold them in place, or by using a crowbar. Make sure to remove all of the insulation and debris from around the wells. Once they are clear, you can remove the wheel well panels.
3. Finally, you will need to access the brake lines. On most cars, they are located behind the wheel wells. To get to them, you will need to remove some metal plates that cover them. On some models, the plates are attached to the car with bolts; on others, they are attached with welds. If the plates are welded on, you may need to

Brake Fluid Levels

If your brake lines seem to be clogged, the first step is to check the brake fluid levels. If the fluid levels are low, you can flush the lines using a brake fluid flush kit. This kit includes a vented hose and a plunger-like device.

To use the brake fluid flush kit, first empty the reservoir on the master cylinder. Then, connect the vented hose to one end of the hose and connect the other end of the hose to the plunger-like device. Activate the brakes and pull down on the plunger-like device until all of the brake fluid is flushed into the reservoir. Finally, release the brakes and refill the reservoir with new brake fluid.

Bleeding Brakes

Bleeding brakes occurs when brake fluid seeps from the calipers and pads, or from the Master Cylinder. This can happen when the brake lines are kinked, or when they become worn.

If you notice your car is making a lot of noise when you stop, or if the brakes feel spongy, it’s probably time to bleed your brakes. To do this, you’ll need some basic supplies: a brake line bleeding kit (or an air compressor), a funnel, and brake fluid.

First, check to see if there are any kinks in your brake lines. If there are, use the brake line bleeding kit to remove the kinks. Next, use the funnel to fill each brake caliper with enough brake fluid to cover the pads. Finally, use the brake pedal to apply pressure to the pedal until the fluid starts flowing from each caliper. Don’t overfill your calipers – you only need enough fluid to cover the pads.

Checking for Warped or Cracked Lines

Brake lines are a vital component of your car’s braking system. If they become warped or cracked, they can cause your car to stop working properly.

To check for warped or cracked brake lines, first remove the wheel and tire. Then, use a straight edge to check each line for any signs of distortion. If there are any signs of damage, you’ll need to replace the line.

To replace a brake line on a Chevy Colorado, first remove the wheel and tire. Next, use a wrench to loosen the line clamp on one end of the line. Then, using a second wrench, loosen the clamp on the other end of the line. Finally, pull the line out of the brake caliper.


If you are having trouble getting your brakes to flush, there are a few steps that you can take to remedy the situation. First and foremost, make sure that your brake lines are in good condition. If they’re not, they will cause problems when trying to flush the system. Second, make sure that your brake fluid is at the correct level – too low and you won’t be able to get the brakes to work properly; too high and it could damage your vehicle. Finally, bleed the brakes as described in our article on how to flush a brake line. If you follow these simple steps, you should be able to get your brakes flushed without any issues!
