Thread: Spongy brakes

On my 05 Silverado my brakes feel spongy and the reservoir level keeps going down but there are absolutely no leaks. Could this be my master cylinder is shot? Thanks in advance.

Maybe the master cylinder, could also be a leaky caliper or rear brake cylinder/caliper. You should check all the brake components for leaks.
Link to my thread when my brakes were going out it has some helpful info from other members:

There has to be a leak somewhere if the fluid is going down. It is not magically disappearing. You need to do what Conlan said and check everything. It could be leaking thru the master cylinder and into the brake booster. If that is the case you should see fluid if you look under your dash where the rod goes from your bake pedal thru your firewall.

From what I have read brake fluid does not evaporate, so if the fluid level is dropping, you have a leak.

now on the booster any leak with the booster will cause a hard pedal.
pedal to the floor is usually the master is bad.
