Why are my brakes so soft after replacing everything?
New front lines, pads, rotors, rear shoes, rear cylinders, drums, springs, adjusters, and levers have all been changed. After changing all this I had a very soft pedal. I bled the brakes three or four times with no affect. So I took it to the local mechanic. He said the master was bad.
What causes a soft and spongy brake pedal?
Corrosion inside that wheel cylinder can cause brake fluid to leak resulting in a loss of hydraulic pressure. This leads to a low or soft/spongy brake pedal. If the vehicle has a rear brake drum/shoe and pumping the brake pedal improves the brake pedal, the rear shoes may be out of adjustment.
What to do about a spongy brake system?
The fix: Find and repair the source of the leak and bleed the system. A faulty brake hose can also cause a spongy feel, it’s a lot less likely but I have replaced plenty especially on older cars. The flexible rubber brake hose fitted between the chassis and the suspension is flexible to allow for relative movement.

What causes spongy brakes after a brake bleed?
Spongy brake pedal after a brake bleed is frustrating but you’re in the right place and we’ll get to the bottom of it in this post. The most common cause of spongy brakes after bleeding, is contaminated brake fluid. Usual contaminates include air or moisture in the system.

Why are my brakes spongy and pedal hits the floor?
But don’t mistake fliud loss for the normal fall of fluid in the reservoir that comes with the wearing of the brakes. Thats exactly why there is a reservior. A common sign of ACTUAL fluid loss is the loss of paint on the booster (brake fluid is an excellent paint remover – wash off with water if you spill it somewhere.
Can a caliper not release cause brake drag?
Just like with the master cylinder not releasing causing the brake drag, a caliper not releasing and staying applied can do the same thing. If only one position is dragging, this could be the case.
What to do if your car brake fluid is spongy?
If the brakes are soft or spongy, this is a good time to change or flush the brake fluid. Flushing the brake fluid, commonly called bleeding the brakes, gets rid of the air. (Bleeding the brakes uses fluid to push air out of the brake system.) Over time, brake fluid absorbs moisture.
Is there a problem with my disc brakes?
There is no loss of brake fluid any where. The master cylinder reservoir is not losing fluid. My truck has disc brakes on all four wheels, and the pads are in good shape. I do not think there is anything wrong with the calipers because the truck does not pull to one side.

What causes a brake pull on a car?
A brake pull may also be experienced if the fluid pressure is reduced at a caliper. As the heart of the brake system, the master cylinder performs a number of important functions: it holds the brake fluid, generates hydraulic pressure, and feeds it to the front and rear brakes. Unfortunately, the master cylinder can wear out and develop leaks.
