I looked up the Buick owners manual. The light does not have a chime with it. It also covers the parking brake not fully released? It could mean failure of part of the brakes but the car is not stopping with only two brakes instead of four and no chime.
 
Check your fluid level in the master cylinder. It seems to me I had that happen when I owned a 93 LeSabre.

#17 of 24 Brake Lines rusting by mack1a

Sep 07, 2010 (11:44 am)

Living in Western New York(Buffalo area), with our winters, and al the rock salt applied to the roads, has caused some of my brake lines to rust out.
Had a line go while on the road, but was lucky enough to have it happen near a GM Dealership.
 
Yesterday, I went to put my '03 Bonneville in gear, and the pedal went to the floor.
Again.
 
Found a rust caused leak in the line going from the rear port on the master cylinder to the ABS.
With my luck, it'll be a "Special Order" part.
 
I'd like to find a diagram of the brake lines, and try to do it myself.
But with the ABS module involved, I'm concerned about bleeding the system properly.
 
I was a USMC Heavy Equipment Mechanic, and have a fair idea of what I'm doing.
 
But I just really don't want to have this sumbitch towed to the Dealership and get rooked.
$$$ is really tight right now.
 
Well, nevermind. It's on the way to the Dealership.
$111 for the Tow, and we'll see what the damage$ are for the work/parts.
 
On the good side, the Dealership has a $30 Rebate for the tow!
 
yippie.

#18 of 24 Front driver side brake sticking by paulnitro

I have a 1995 Bonneville. The front driver side brake was sticking to the point that the pads completely wore off. I thought that maybe the brake caliper froze so I replaced the brake caliper and pads. The front driver brake still sticks. Any help is greatly appreciated.

There also can be a problem with the hose. The interior of the hose comes apart and blocks the return of the fluid. I wonder if there can be a problem with the ABS system also not allowing the fluid to return.
 
Does the caliper on that side stay hot while driving? If it's dragging it would be very hot even if not used for stopping. Try stopping using the parking brake after driving along at slow speeds. If that front brake is not hot, your problem is the brake caliper on the other side is frozen and not applying. Therefore the left front brake is doing all the work stopping the car. It would wear out the pads quickly because the other side is not doing half of the work. The fronts do most of the stopping work on the car; the rears usually do only a low percentage of stopping work.
 
But I recall some early GM cars where the rear calipers on the disk brakes would rust up and not do any work. The fronts were doing all the work and people kept having to replace the front brakes often. They didn't realize the back brakes weren't helping any and the problem wasn't the front calipers and pads but was the rear calipers.
 
I believe your 95 is built like my 93 and 98 leSabres. There is a pin and a rubber grommet on the outside that fits in the caliper ears. The huge amount of rust inside the ears after winter salt for years here in Ohio filled up the space some pushing hard on the rubber which pushed hard on the sliding caliper bolt. Replacing the caliper fixed that. If the caliper wasn't replaced, the ears were supposed to be reamed out with a brake cylinder type hone to remove the rust thickness to free up the rubber grommet.
 
Check your caliper for sliding action on the other side. See if it's frozen up.

Well this past weekend I replaced both front brake hoses and so far so good!!!! I hope this was the problem. Thanks for your help. I really appreciate it.

#21 of 24 brake problems on A 92' bonneville se by awiley

Did you allow the level of fluid in the master cylinder to go down to the bottom?
Did you open the line to replace the calipers and leave it off so that it drained?
Do you have a leak?
You need to start with the rears and bleed to the front from the longest line to the shortest.
You may have a leaking rear wheel cylinder on the drum brakes.
 
MOST LIKELY IS A PROBLEM WITH A CORRODED BRAKE LINE. With age this is becoming a problem on some of the H-bodies.
 
If you did not let the fluid get down the bottom of the master cylinder you may not have to bleed it. There is a procedure for bleeding it and I am not knowledgeable about it. It may need to be removed to do the bleeding. You should get expert help about the master cylinder and bleeding it, if necessary.

Mine just did that. I have a 98, and the bad news is check your brake fluid. Mine came on right before my break line busted through. Normally means your just getting low on fluid
