Explanation : If your brake pedal suddenly sinks to the floor, try pumping it to build up pressure. If that does not help, use your emergency or parking brake – but use it gently. Shifting to a lower gear will also help your vehicle slow down.

The switch is located right near the tip of your right foot near the brake pedal, so it’s easy to access. The switch may actually snap into place without the use of any tools at all.

In most cars, the brake light switch is installed right above the brake pedal. Inside, it has a one- or two-way electric switch. The most common symptom of a faulty brake light switch is when brake lights don’t come on or stay on all the time.

Driving with a ‘soft’ brake pedal is extremely dangerous because your brakes could fail at any moment, even if they don’t fail they will be inefficient, possibly leading to an accident. It could just be that something is jammed under the brake pedal.

The most common cause of spongy brakes after bleeding, is contaminated brake fluid. Usual contaminates include air or moisture in the system. Most common causes, include: Brake bleeding technique.

It will only go away if you chase it away. That means the brake lines need to be bled to remove the air. When there is air in the line, you are not transferring the force of the brake fluid, but rather compressing the air. It takes a lot more pressure for air to activate the brake calipers than it does brake fluid.

During brake bleeding, the master-cylinder cap should be left unscrewed but still in place atop the reservoir. With the car’s engine off, have your helper pump the brake pedal for several strokes until they feel solid resistance underfoot.

You can check the bleeder screw while getting the air out of the brake line. At the same time, remove the screw completely and put your finger carefully into the hole. Tell your friend to slowly pump the brakes until the fluid starts coming out and touches your finger. Fill up the reservoir before this process.
