There are three common reasons why your brake pedal may sink to the floor. All of them signal a problem with your brake system. Car Doctors Auto Repair explains that a sinking pedal is usually caused by an ABS unit leak, a brake fluid leak, or a problem in the master cylinder. No matter the cause, fixing the problem should be your priority because you may be unable to stop your automobile if you keep driving it.
Brake Pedal Resistance
Your vehicle’s brake pedal should always give you just about the same amount of resistance. It shouldn’t feel soft or squishy, nor should it sink to the floor. If you drive an automobile with power brakes, the resistance causes the pedal to stop at about 1 1/2 inches from the floor. Manual brakes give greater resistance, causing it to stop at about 2 to 3 inches from the floor. Changes in how it feels underneath your foot indicate a problem with the brake system.
Sinking Brake Pedal
As we said above, a sinking pedal indicates a problem with the ABS, brake fluid, or master cylinder. Usually, your brake pedal will sink if the ABS or master cylinder cannot maintain the proper hydraulic pressure. This inability to maintain hydraulic pressure will not only make your brake pedal sink to the floor, but it will also make it much more difficult to stop your automobile. A brake fluid leak will also release much-needed hydraulic pressure, and your pedal might also sink if there is air in the brake lines.
Other Signs of Brake Trouble
Aside from these problems, you may also notice other signs of brake problems that need your attention as soon as possible. It’s never a good idea to drive an automobile that is suffering from brake problems. As you know, anything wrong with the brake system could make it impossible for you to stop your vehicle. Other signs of brake trouble include
- A brake or ABS dashboard warning light
- Grinding, scraping, or squealing noises
- Burning chemical or carpet smells
- Pulling to the side when you brake
- Wobbling or vibration when you brake
- Smoke coming from the brakes
The latter accompanied by squealing sounds is a sign that your brakes are overheating and on a very quick road to failure. If you suspect that your brakes are too hot, pull your vehicle over right away and allow the brake system to cool off. If it overheats when you start driving again, call for a tow truck to tow you into our shop.
