why do i need to bleed my brakes if i never opened the system?

just changed my brakes and roters


Brake lines are sealed pretty well, but the seal isn't perfect. Trace amounts of fluid escape over time, and trace amounts of air get in. This is perfectly normal. If you have to bleed your brakes every month, there is a major leak, and you need to find it.

as the brakes wear down it creats a space in the master cylinder that takes in air. U have 2 get the air out. its also a good idea 2 change ur brake fluid every 3 years.

Did you pump the brakes back and take up the slack from the new pads? Once you compress the caliper - replace the pads, there is still play there, and you have to do this. You can still get air in the system - also check for leaks

Where ever you bought the blades they should put them on for you. Take it back to them.

They should snap off pretty easy, but if you can't see how, drive over to your local auto parts store they will take care of it for free. You learn something every day huh?
