Is it possible to have intermittent brake failure?
The brakes would work perfectly fine but very rarely you would hit the pedal and foot to the floor and nothing, pump the brakes and 100% fine again, scary. Popped a new master cylinder on there and never had an issue again.
What causes a hard brake pedal to intermittently work?
Hard Brake Pedal Intermittent – Vacuum Pressure. Vacuum – or really lack of vacuum pressure – is the most common cause of a hard brake pedal, and therefore the first thing to look at when a hard pedal is present. Any brake booster (whether from Master Power or any other supplier) needs a vacuum source to operate.
When do you know you have a brake problem?
If you notice a difference in the resistance in the brake pedal — it feels “softer,” or sinks all the way to the floor mat when you press on it — it’s a sign you need immediate service. There could be air or moisture in the braking system or a problem with the master cylinder.
What happens when you hit the brake hard?
If you hit the brakes hard (like a sharp initial tap on the pedal) they would work fine, but if you eased onto them they went right to the floor. This was, of course, an intermediate step towards brake failure, so I suggest you park the car until the braking system is fixed.

How to check for intermittent soft brake pedals?
Intermittent soft brake pedal 1 Bleed brakes / check brake fluid for funk/air bubbles, etc. 2 Check out master cylinder 3 Possible ABS issue….will probably take to garage for that one.
When does the brake light come on with hydraulic failure?
With an hydraulic failure (the symptoms of which would be the pedal going to the floor) the brake light should come on. As a test of the bulb, when starting the light should come on briefly and go out. Where the MC attaches to the booster, are there any signs of fluid leakage? Intermittent problems can be really tough to diagnose.
How does the foot brake work in a car?
Commencing with the foot brake system, it is a pedal connected to vacuum booster, which is used to stop or slow down the vehicle’s motor. This is also known as the system of hydraulic brakes that multiplies the foot-force applied in order to stop the car weighing several tons.
When to use pedal brake or foot brake?
Besides this, on hill start (sharp slope- upward or backward), the brake really helps against rolling forward or backward. On the other side, the pedal brake is mainly used to slow down or completely stop the moving car. Hopefully, gaining the industrial knowledge on handbrake and foot brake will enhance your driving tips and skills, too.
Why do my turn signals stop flashing when I apply the brake?
Make sure you have the right bulbs in and check the wiring harness on your lights and take a look inside the light assembly for any short circuit. Also any addition like the third brake light and, like mayer said, a trailer light plug that is shortened can do it too. Good Luck to you Was this answer helpful?
Why does my car make a noise when I put my foot on the brake?
Usually this is because the brake pad wear indicator is touching the rotor. If the wear indicator is touching the rotor, sometimes the noise disappears when you apply the brakes, and returns when your foot comes off the pedal. If you hear this type of noise when you’re not applying the brakes,…
Why do my brakes Squeak After sitting for a long time?
Most brakes squeak after sitting overnight. This is usually due to moisture from rain, dew, or condensation that collects on the surface of the rotors. When moisture collects on the brake rotors, it causes a thin layer of rust to form on the rotor surface.
What kind of car squeals when the brakes are applied?
Annoying squeak/squeal from car but stops when brakes are applied. Its a 6 yr old merc b class and it squeals all the time until you touch the brakes. Garage has checked the pistons and wheel bearings and said they were fine.

What should I do about intermittent brake locking dragging?
New rubber brake hoses in both front brakes. New wheel cylinders in both back brakes. New caliper with piston assembly in front driver side. Passenger side is fine. New wheel bearing in front driver side (there was visible smoke from front driver wheel when it first happened). Other bearings are fine.
