On your problem with the HONDA..
You are right the Problem is the BRAKE BOOSTER.
But before replace Inspect the Vaccum hose coming from the Intake manifold, Check for proper vaccum,
If everything is ok.
JUst replace the BOOSTER And the car will be ok.
Because the Brake Booster is LEAKING vaccum air.
And the ENgine will come at high IDLE..
Is why the engine will Run and DIE.

DON'T drive the car until you fix. Because is Danger for not Brake response.

OK.. I hope this help to fix your Honda.

How to diagnose a bad brake boosterOn my 95 GMC Suburban K 1500 4 x 4 5.7 v8

Hi, your basic symptoms will be. Your brake pedal. Will be very hard to push. When the pedal is engaged there will be a large vacuum leak, usually causing the engine to be very ruff or stall. If its bad enuff, youll hear the the air leak when pedal is depressed, hope that helps.

Brake lines probably broke. brakes stopped working suddenly.

There are many things other than brake lines that can cause braking loss. Investigation will reveal the issue. First, check fluid level in the Master Cylinder. If the level is normal, you don't have any broken lines/leaks. If the fluid is full and you have no brake pedal/braking power, chances are the Master Cylinder itself has failed. There are o-rings internal to the M/C that can fail, and when this happens, you will lose pressure to wheel cylinders/calipers and, as a result, lose your brakes.

If the fluid has leaked out, then you need to find out fro where. This is not too difficult normally. Fill the M/C with fluid and have someone press the brake pedal while observing the underside of the vehicle. You should see fluid dripping from somewhere, often near one of the wheels. You can have a leaking caliper/wheel cylinder, brake hose, or metal brake line. Once you determine what part has failed, you can purchase and replace the defective part. Brake calipers, wheel cylinders, and hoses are fairly simple to replace. Brake lines are more difficult, as they require shaping, cutting, and the creation of couplings. After repairs are done, the brake system must be refilled and all air bled from the system or braking will not be satisfactory.

02 Ford Explorer sporttrac xlt. New rotors calipers pads and master cylinder. Bled it twice stream looks good new fluid. One day breaks stick then the next no breaks Break light on Proportional valve?

For some reason these vehicles you need to bleed brakes several times, had same problem, so air hangs up in lines somewhere it apears. When you say brakes sticks, describe it better, locked up, or dragging on rotors?

I have a 2005 gmc envoy and the pedal brake was too hard en i did change the calipers , brake hose lines and power booster , and for few weeks still doing the same and now i have brakes but the some yimes...

Usually a hard brake pedal is the brake booster. Since you replaced that it is out f the picture (unless the replacement was bad). This issue of the pedal going to the floor is troublesome and potentially dangerous. If it is not doing it all the time, it probably soon will. What most likely occurred, and this happens quite often, is that after having had the hoses and calipers replaced, it was necessary to bleed the brake system of air in order to get proper brake operation. This requires depressing the brake pedal numerous times to the floor while purging air from the system. There is a potential problem in this and that problem is that the o-rings in the master cylinder can be damaged by the bleeding process, because the normal stroke of the master cylinder is much shorter than the one used during bleeding. This sometimes results in o-ring damage because the master cylinder bore may have worn a ridge in it where the normal stroke ends. The repeated passing of the o-rings over the ridge will damage them and can cause them to fail. When this happens the pedal will drop to the floor. You really can't blame the mechanic for this but it most likely happened as a result of the work done. Have the master cylinder replaced ASAP. I wouldn't recommend using the vehicle at all in the meantime.. it is a pedal-press away form total brake failure at any given moment.

I have been working on power brakes and bleed system and got a good pedal pressure

try bleeding the brakes with the engine running there may still be some air in the system. make sure the master cylinder doesn`t run out of brake fluid.

Fiat 500 brake lights on permanently - loss of engine power

Does it pull to one side or the other when rolling? If so, then you may have a stuck caliper. If not, then you likely have a bad master cylinder and need to replace. If it is a stuck caliper, it would be wisest to replace BOTH calipers. If the brake pedal feels hard when you push, that would be another indicator the master cylinder is bad - but you may not have the hardness in the pedal. If pulling up on the pedal relieves the problem, I would suspect the master cylinder first. Driving on it could damage many components, and replacing them all may be expensive - I recommend verifying the master cylinder is bad and replacement before driving!!

2005 silverado brakes sticking front only after driving little

I had the same problem and replaced both calipers with no change, I figured it was the master cylinder. When I pulled off the master cylinder I saw the vacume booster had about 2 cups of brake fluid in it which leaked from the front of the master cylinder. I replaced master cylinder and vacume booster and brakes work great now.

Front brakes stick on

either your calipers are sticking and need replacing. OR the hoses have failed internally. and need replacing.. very rare but possible the master cylinder is not allowing the fluid to return usually caused bu a booster failing and causing some down travel in the master cylinder. I'd start by raising the front end up. appling hard brake pressure. turn the tire.. then loosen the brake bleeder to check for pressure. if the bleeder sprays fluid and the brakes release forget the calipers. if they are still tight then replace the calipers. pump them up again if they released.. and break the line free at the master cylinder. if they don't release then replace the hoses..
