Yes. You need to get all the air out if the system
After servicing or replacing a wheel cylinder, the brake system must be bled to remove any air that may have entered the hydraulic system. This is crucial to ensure proper brake function and responsiveness, as air in the brake lines can lead to a spongy brake pedal and reduced braking efficiency. Bleeding the brakes helps restore the integrity of the hydraulic system, ensuring that brake fluid can effectively transmit force to the brake components.
the brake system needs bled. meaning the system has air in it and the air needs removed. through the bleeder valve
Air can enter a hydraulic brake system primarily through two ways: first, through leaks in the brake lines or fittings, which can create a pathway for air to infiltrate. Second, during maintenance procedures, such as replacing brake fluid or components, if the system is not properly bled, air can be introduced into the hydraulic lines. Both scenarios can lead to decreased braking performance and the need for proper maintenance to ensure the system is sealed and free of air.
You have air in your brake lines. Have the brakes bled.
Master Brake cylinder replaced and lines bled-how long?
May have air in the system and have to be bled Check the flexible brake lines (front) to make sure they are not ruptured and are ballooning when brakes are applied
If your brakes are new and the system has been bled, your next step is to see if you have a leak in any of your brake lines and also check your brake master cylinder to see if it's working or not.
check your brake fluid level. its probably empty for some reason...leak? If the fluid level is correct than you most likely have air in the brake lines and will need to have the brake lines bled.
If you suspect that there is air (or other contaminants) in the system, or if the lines have been disconnected for any reason, then yes, the brake lines need to be bled. If you've only replaced the brake pads/shoes, etc., then there is usually no reason to bleed the lines except as indicated above.
they are bled to remove air out of your brake system. bleeding prevents you from having mushy brakes or your pedal going to the floor. it also makes the pedal tight and more sensitive to your feet.
The brake hydraulic lines may still have to be bled or you may have gotten grease on the rotor.
Usually when a brake pedal feels more stiff than usual, there is a vacuum leak. The brake lines probably should be bled.
