What is a Brake Flush? 

A brake flush is simply the process of removing and replacing the fluid from all types of brake systems. 

A lot of people are quite confused between a brake blush and brake bleeding. But they are different. 

The entire fluid gets removed and replaced in brake flushing. 

In brake bleeding, only a portion of the fluid is removed. 

Is Brake Flushing Really Necessary? 

Of course! Brake flushing is imperative. 

Although companies built brake systems to last, their quality declines after some time. The rubber parts in the cylinder’s valves, for example, have a higher risk of deterioration. 

The brake calipers and wheel cylinders are no exception. They start to chip off over time. 

The brake metal particles and dust begin to accumulate, especially in joints. Don’t leave them unattended for some time as this can cause contamination. 

Brake flushing can prevent this contamination from happening. But it should be done on a regular basis.

  • Prepare all necessary tools.
  • Open the hood. Then, find the master cylinder. 
  • Open the mass cylinder. 
  • Suck up as much fluid as you can using a turkey baster. 
  • Fill the reservoir with new brake fluid. 
  • Check which calipers you have to bleed first. Use the instruction manual. 
  • Jack up your car.
  • Make sure to remove the wheel properly and find the bleeder valve. 
  • Pop valve open and let your friend pump the brakes until dirty fluid comes out. 
  • Top off the master cylinder with quality and new fluid.

Good news! There are companies that provide a brake system flush service you might consider. 

But how much does it cost? It ranges from $73 to $104 for vehicles of any size and type. It is pretty inexpensive and won’t break your bank. Instead of a DIY brake fluid change, let the expert get the job done. 

4 Reasons Why You Should Flush Your Brake Fluid

  • Both traction control and ABS systems break down the fluid – Refilling the tank is a wise idea.

  • Traction control and anti-lock braking components are less permeable to moisture – Let fresh and new fluid gets its job done.
