Why does my brake pedal go to the floor after changing pads?

If your car has rear drum brakes and the brake pedal goes to the floor, the rear brake shoes could be out of alignment. Sediment. Sometimes when new brake pads are installed, sediment can inadvertently be pushed back into the hydraulic system. This sediment can damage the master cylinder.

Why is my brake pedal soft after changing pads?

Air in the brake fluid is the most common cause of low, spongy brake pedal feel. Moisture in the fluid will not substantially change the pedal feel until the fluid temperature exceeds the boiling point of any water in the fluid, then the pedal feel gets very soft.

Why is my brake pedal pushing all the way to the floor?

One of the most common reasons for your brakes touching the floor would be an issue with your brake fluid. Your fluid being low or air reaching the brake line will prevent the fluid from flowing properly, resulting in a spongy pedal. A bad brake booster is another common cause for a malfunctioning pedal.

Why are my brakes not holding pressure?

This can be due to a number of problems: a leak in a brake line, a loss of pressure within the master cylinder itself due to a failed seal, or air being introduced into the braking system. Your first reaction to encountering spongy brakes should be to rapidly pump the brake pedal with your foot.

Breaking in new brakes is also known as bedding-in the brake pads and rotors. If you don't properly bed in brakes, you may experience problems with the braking system down the road, such as warped discs, uneven brake pad wear, or noise brakes every time you tap on the brake pedal.

Why do my new brakes take longer to stop?

Many times, this situation comes from the driver stepping on the brakes too hard or trying to slow down too quickly, before the lining has seated into the surface of the brake rotors. After that first 500 miles without overheating the pads, your new brakes will be ready for a few harder stops.
