Hi

Since your brake fluid level has not gone down, leaking calipers or hoses, letting air into the system can be eliminated.
Suggest you run engine, and sit with your foot on the brake pedal quite hard, and see if it drops drastically.
If so, this points conclusively to the brake master cylinder, and being a 2001 model, is a distinct possibility.

By the way, as you have dual system braking, you should never loose your brakes completely, nor the pedal reach fully to the floor.

The other possibility is excessive play, in one of your front hub wheel bearings, allowing the brake pads to be pushed back on cornering, then on first application of the brakes, you will have to pump the pedal.

Hope I have been of some help.

Good Luck !

Please don´t forget to give me a FixYa rating thanks !

John.

You need to bleed the brakes you have air in the lines.If you do it your self remember to start at the farthest caliber from the power brake booster.

This is often the result of a tire that is out of balance. Check for bubbles on any of the tires and have the tires balanced. That should clear up the problem.

Brakes are very touchy after sitting


I thought the caprice had disk on all wheels?? But it sounds like it's time for the rear brakes to be serviced. If you do have rear drums the pads could be worn and the shoes are slipping and grabing. You can try backing up in a empty parking lot and backing up and giving full brake application. About the 7th application would reset the brakes, if that does not help then the breaks need to be serviced. Good kick
