In a 1992 Bonneville if your brake pedal goes all the way to the floor with no pressure what could the problem if no fluid is leaking?

You have a serious brake problem. For your own safety have the vehicle towed to the garage of your choice for repair.

Check the "Related Questions" below to see if your problem is related to a leaking brake pressure switch - causing a range of problem, including the #10 fuse blowing.

The brake booster is leaking vacuum pressure. If you look under the hood its black and round and located behind the brake fluid reservoir

When a brake line is leaking on the Chevy Venture the brake line should be replaced as soon as possible. A leak, however small, can cause hydraulic fluid to escape the brake line which will cause a loss in brake pressure. The brakes should be bled of air after the new line is put in to remove gaps in brake pedal pressure.

Start with the vehicle speed sensor the feeds the speedometer and odometer.Also look at the Brake/Speedometer problem associated with the Windstar recall for a leaking brake pressure switch

brake fluid leaking from a brake drum indicates the brake slave cylander on that wheel is leaking and needs to be replaced you will not see the actual leak with out removing the brake drum

I had this problem on a 94 Bonneville after we had fixed the brakes. After I disconnected the battery and reconnected the light went off and the dinging stopped. Not sure if this was related or just coincidence.

Seal in brake caliper is leaking and needs replacement Flexible brake line to the caliper is leaking and needs replacement

One reason: Leaking master cylinder resulting in brake fluid leaking onto the braking mechanism, causing a failure to grab and then excessive grabbing as the pressure on the brake pedal increases

Usually, a loss of pressure in your brake system means that there is a hole somewhere in the system. A leaking brake line or a punctured reservoir could cause a loss of pressure. A bad master cylinder could also cause a loss of pressure in the back brakes.

Brake problem. Remove the rear wheel & brake drum, and inspect the brake components. You may have a leaking wheel cylinder or other problem. Also inspect the wheel bearing.

brake pressure loss and pedal going straight to floor is mostly caused by loss of brake fluid or air in brake system look under car and on inside of wheels to see if fluid is leaking. check brake fluid level at master cylander if no fluid seems to be leaking, have the brake system bled for air. this is the simplest remedy to start with if that doesnt fix it have the brake power booster checked to make sure fluis is not leaking into that also check on firewall in engine bay round booster for fluid and on inside of cab on firewall for fluid

Check the level of hydraulic oil (aka brake fluid) in the clutch master cylinder reservoir. If it is empty you found your problem. Either the master or the slave cylinder is leaking.

It all depends on what part is leaking what fluid. Brake cylinder would leak brake fluid. Axle seal would leak gear oil.

I have the same year and model car, and this occasionally happens. in my car, it's because the master cylinder is bad and is leaking brake fluid. the beeping indicates that the reservoir is low on fluid. until I can get it fixed, I just always be sure to have brake fluid in the :S hope that helped.

Generally speaking, soft or spongy brakes can be caused by - Wheel bearings that are out of adjustment Brake shoes that are out of adjustment Brand new brake linings that haven't 'bedded-in' yet Air in the braking system Other causes can be - Brake components not secured properly Worn or damaged self adjusting mechanisms Wrong brake components fitted Wet or damp brake linings Seized or partially seized brake components - wheel cylinders or caliper pistons Expanding brake hoses Brake system component seals leaking or not holding pressure and lastly................. Contaminated brake fluid or the wrong type of brake fluid ---------------------------------------------------------- Okay, that's quite a list, so lets get down to it........ Chock the wheels to prevent the vehicle from moving. Release the parking or hand brake. Clamp off all the flexible brake hoses and test the pedal pressure. If the pedal pressure is poor the problem lies with the master cylinder. If the pressure is good then release one of the clamps you placed on the brake pipes and check the pedal pressure again. Carry on until you release a clamp and the pedal pressure becomes poor - this will indicate the area on the vehicle where the problem lies. Refer to the list above to guide you to finding the solution to your problem.

When brake fluid leaks the system is compromised and the brakes might not function properly. Look over the entire brake system to see where the leak is coming from to be able to fix the problem.

The power brake booster is leaking vacuum.
