Brake piston pusher: work and cost

The brake piston repeller is a professional tool for changing brake pads. In fact, the brake system includes pistons located in the brake caliper that push the pads against the disc to slow your car down.

🚗 What is the brake piston repeller used for?

Le brake piston push back an indispensable assistant for the correct replacement of the rear brake pads of your car. However, to understand the usefulness of the piston repeller, it is necessary to fully understand the principle of operation and the various parts that make up the rear braking system.

Indeed, the rear braking system consists of:

• of brake calipers : they are attached to the wheel hub. This is the part where the brake fluid and brake pads are located.
• of brake discs and pads : brake pads are made up of a lining that presses on the brake disc and thus slows down the rotation of the wheel.
• of brake pistons : These are the sliding parts placed in the brake caliper. The role of the pistons is to push the brake pads against the brake disc in order to slow down and stop the car. The pistons move due to the pressure of the brake fluid when the brake pedal is pressed.

Thus, over time, the brake pads will wear out due to friction against the brake disc. Therefore, it is very important to have pistons that will compensate for the reduced thickness of the brake pads.

However, when replacing the brake pads, the pistons must be pushed back so that the worn out brake pads can be removed and the new brake pads reinstalled. Thus, thanks to the piston repeller, you can move the pistons in order to be able to replace the brake pads.

🔧 How to use the brake piston repeller?

Using a piston repeller is quite simple, but you still need to know how to use it. In this tutorial, we will explain how to replace your car's brake pads with a brake piston repeller. Here are the steps to follow.

Required material:

• The brake piston extends back
• Toolbox
• New brake pads

Start by disassembling the brake caliper by unscrewing the mounting screws. We also remove the brake pads.

Step 2: Open the brake fluid reservoir.

After the brake caliper has been disassembled and the pads removed, open the brake fluid reservoir to facilitate pushing the piston and avoid pressure build-up in the brake fluid.

Step 3. Use piston repellant.

You can now use your piston repeller by jamming it like in the photo above. Then you just have to screw in the piston to move it away. After the piston is depressed, you can unscrew the piston repellant to move it out of place.

Step 4. Collect the various items.

You can now install new brake pads and assemble the brake caliper. After assembling the brake caliper, close the brake fluid reservoir and depress the brake pedal several times to re-pressurize the brake fluid and move the brake pistons. Pump the pedal until it hardens.

💰 How much does a brake piston repeller cost?

The price of a brake piston scarer varies greatly depending on the quality of the tool. You can find inexpensive piston repellents online at: 20€... But the price of a professional piston repeller is included. from 180 to 200 €... Therefore, it is a relatively expensive tool.

If you only use your piston piston repeller a few times a year, we advise you to choose an economical solution with a cheap brake piston repeller. However, if you regularly use a piston repeller, choose a high quality brake piston repeller.

Now you have all the important information for using a brake piston repeller. However, if you don't feel the soul of a great mechanic, feel free to walk through one of our trusted mechanics. With Vroomly, you are guaranteed to find the best garage for the best price for your brake pad replacement!
