1998 Chrysler Cirrus Low pedal

Worn pads will not cause a low pedal. Worn rear shoes won't either unless the automatic adjuster star wheels are rusted tight. Apply the parking brake, then see if you have a normal pedal. If it comes back up to normal, suspect rear shoes out-of-adjustment.

If the master cylinder is defective, the red warning light should be on. Also check the rubber seals under the master cylinder caps. If they are mushy and twice their normal size, the fluid is contaminated with petroleum product. In that case, ALL parts containing rubber must be replaced, and the lines must be flushed and dried. If you have anti-lock brakes, the hydraulic control assembly must be replaced because it contains rubber seals.

If the brake pedal is only low when driving, not when standing still, jack the front end off the ground and check for sloppy front wheel bearings. They will usually become noisy long before the get sloppy, but a wobbling wheel will push the pistons into the calipers. The next time you apply the brakes, you'll have to move a lot more fluid to push the pistons back out to the rotors. This results in a lower than normal pedal.
