YES...because, the rubber breaks down from the inside causing blisters that restrict the flow of fluid to the caliper.
You have something wrong with the drivers side front brake. It is not working that's why it pulls to the right. Could be a bad rubber brake line that's not letting fluid through when brakes are applyed. A sticking brake cailber can cause this also. Pull front wheel and check things out.
Air being charged to the brake system. When you pull the brake valve, the air in those lines gets purged. When you release the brakes, it has to refill those lines and chambers.
air still in lines. rebleed
Time for new brakes or adjustment.
Sounds like a brake problem. Need to pull wheels and check the brakes.
You have a problem with the brakes, have a mechanic check it out soon before you have no brakes.
when you pull back on the reins.
first check for contamination, pull master cylander cap off, if it has rubber underneath the cap and it's expanded or heavily distorted a petroleum product (such as oil) is in the system. the whole brake system will have to be redone, including brake hoses, mc, prop valve, height sensor, and any thing else rubber relatted in the system. also over adjusted rear brakes or over adjusted e brake can cause this. but check for contamination first this is a serious safety issue.
Yes, applying the brakes on a bicycle should slow it down. Little squares of rubber are pressed to the metal rimming on the bicylce's wheel when you pull a handle brake, or pedal backwards (depends on if it's an adult bike or children's bike).
rubber band,cork;
slowly push it along then pull the brakes, if it stops, THE BRAKES WORK!!! if it keeps going, THE BRAKES DON'T WORK!!! IT'S ROCKET SCIENCE!!!
Warped brake rotor(s). Brake pads and calipers should also be inspected.
