When changing pads, do the brakes need to be bled?
Your braking system is the most important one in terms of essential parts. You must be able to stop at any time, no matter how quickly you’re moving. Hydraulic braking systems for vehicles operate by pushing pressurized fluid. There will be less pressure, spongy-feeling brakes, and lengthier stops if there is an air bubble in the system. But that’s only the start. The car might not stop at all if left unattended.
There is a technique to avoid this in addition to fixing it. Let’s examine when and how brakes should be bled.
When to Bleed Your Brakes
First off, you aren’t truly bleeding brakes; rather, you are removing air bubbles that may have developed prior to pouring fresh brake fluid by bleeding fluid and air out of the braking system.
When should you bleed your brakes?
- when the brakes begin to feel soft.
- when pauses take longer and you start to lose confidence.
- if you discover a leak Air may also be let in through leaks in addition to fluid. Bleeding your brakes after fixing the leak is the only way to ensure that your system isn’t affected by an air bubble.
- if you’re changing out worn-out brake pads, as this could lead to air getting into the master cylinder. More brake fluid is needed while braking with worn brake pads, which empties the reservoir and leaves room for air.
- if you replace your brake pads or rotors. For the purpose of safety, every brake job needs to include a brake bleed.
- As part of good preventive maintenance, once a year.
How to Bleed Your Brakes
You’ll need a screwdriver for Torx screws (detectable by the six-pointed groove on their heads), as much fresh brake fluid your car needs, and a container to catch the used fluid for all four methods of bleeding brakes.
Here are the four techniques for bleeding brakes:
- Put a container underneath the bleeder screw, turn the screw to let the old fluid fall into the container by gravity. Afterward, there will be cleanup. The liquid won’t fall in a straight line; instead, it will drip down components in the space between the container and the bleeder screw.
- By hand: Place a container beneath the bleeder screw and open it as someone gently presses and releases the brake pedal, forcing the fluid and air out of the system. Smoothly use the brakes to prevent the formation of further air bubbles that could linger and contaminate the fresh fluid. Make sure the fluid isn’t frothy, as that indicates that new air bubbles are beginning to form.
- Once more, place a container under the bleeder screw and open it to provide pressure. The fluid and air should then be forced through the system and into the container using a tank of pressurized braking fluid at the master cylinder.
- Vacuum: For this technique, when you open the bleeder screw, fasten a vacuum bleeder to it. It extracts the liquid and air into a connected container.
Regardless of the route you take, bleeding your brakes when there is a problem or as part of routine maintenance ensures that your braking system operates as effectively as possible and keeps you and your passengers safe.
