Yes. You need to get all the air out if the system
the brake system needs bled. meaning the system has air in it and the air needs removed. through the bleeder valve
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
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 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.
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.
Spongy brakes on any automobile are usually caused by air in brake lines. The lines need to be bled according to the owner's manual.
"Spongy" brakes on any car are an indicator of air in the brake system. The most common way for air to enter the ststem is if the brake lines are disassembled during brake repairs. If your brakes have not been serviced, the most likely explaination is that you have a leak somewhere and you have depleted the brake fluid in the master cylinder reservoir. ADDING MORE FLUID WILL NOT HELP. Once the fluid is depleted, the master cylinder pumps air into your system. Regardless of the source of the air, the system must be "bled" i.e. air sucked out of the lines. If you do not know why you lost brake fluid, find the leak and fix it first.
