In that case, start tracking back. The turn signal switch pulls the brake light out of circuit when the signal is operating. If the switch fails, the one or both stoplights can stop working.

You put brake fluid where power steeling is supposed to go in is this a big problem can you just take it out and put right fluid in the car was ran only 15 minutes at most?

Both the power steering pump and the brake booster operate hydraulically. Putting brake fluid in the power steering pump will not harm it since brake fluid is a light oil only with different properties. I would only worry if it were the other way around and you put power steering fluid in the brake master cylinder. Power steering fluid doesn't have the heat range or density of brake fluid.


What causes the car to noticiably idle higher sometimes when you stop?

The vacuum brake booster is connected to the engine through a large vacuum hose directly to the intake manifold. The power brake assist is dependent on the engine vacuum to operate, and allows air into the intake manifold whenever you press on the brakes. A certain amount of increase in engine idle speed is natural when you press the brakes, however, if there is too much idle increase, you may want to have the vacuum booster tested for leaks. The power brake system can still work while there are relatively small leaks in the booster, but if there are leaks now, they will only get worse and can potentially cause problems with the power brake system. That may not be your problem, but it would be a good idea to have it checked.

What is brake booster?

Brake boosters are used only on power brakes, not manual brakes. The booster's function is to give more braking power with minimal pressure on the brake pedal. If the booster is not working properly, you will still have brakes, but the brake pedal will be very hard to push.A brake booster is what gives power brakes their power. It works on vacuum from the engine. The booster pushes on the master cylinder with the pressure applied to the booster by stepping on the brake. If the engine is off, it cannot get vacuum, therefore the brakes will be hard when the engine is off. This is noticeable when pushing a stalled vehicle and stepping on the brake.ConstructionThe brake booster is made of five parts: the booster piston, body, booster return spring, control valve and reaction valve. The body has two chambers--the variable pressure chamber and constant pressure chamber--separated by a diaphragm.TypesThe brake boosters 's size and whether it has a single or more than one diaphragm depend on the year, make and model of the vehicle. When ordering a new booster, tell the auto parts store or dealer the year, make and model of your vehicle, and they will give you the correct one.


Does mixing kerosene with fuel in an octane engine produce a better output if so will it damage the engine?

your car will become a rocket but only for a while because the engine will probably brake.


How can you fix the mistake of putting engine oil in where the brake fluid goes?

If you only added engine oil to the master brake cylinder reservoir, remove the master cylinder and replace it with a new one. Engine oil in the brake system will destroy all rubber parts and seals, so if the engine oil worked its way to the calipers and wheel cylinders those would have to be replaced also.
