I broke and replaced the brake line from the caliper to the brake hose while replacing my front rotor. After I put everything back together and refilled the fluid back into the brake reservoir, but my brakes does not work. The calipers doesn't seem to be clamping down at all. It's it because I let too much air into the system when I was replacing the brake line? Will bleeding the brake system solve this problem? Any help will be appricated. Thanks.

 

yes, you ALWAYS bleed the system when you disconnect the brake lines (even if it's just one). You will prolly have a lot of air in the system. Have someone help you, and do all four calipers.
