TOYOTA BRAKESYSTEM and its functioning is quiet simple but should be the first priority when comes to safety and security. Toyota Camry, Toyota Corolla, Toyota Venza, Toyota Avalon and every other model of Toyota use Toyota Brakes.
We know that by pushing a brake pedal we can stop a moving car. But what's in the pedal which causes some pressure by our legs to stop the movement of such a big car? A brake is a device which helps slow or stop the motion of vehicle by applying force on it; otherwise it is a device which helps to restrain the vehicle from movement. While the brake pad is pressed the caliper housing the piston thrusts the pad towards the rotor which eventually slows or stops the wheel.
Any braking system functions via friction to stop the vehicle and in the process convert kinetic energy into heat energy. Automotive breaking system can either be disc brake or drum brakes or a combination of two:
- Drum Brake: In drum brakes friction comes from a set of brake shoes that clasp to the inside surface of a rotating drum connected to wheel.
- Disc brake: The disc brake work through a rotor usually made of cast iron or ceramic composites connected to a wheel or axle. To stop the wheel brake pads which are fixed on brake caliper are pressed mechanically from both the sides. Different components included in brake system are Master Cylinders, Brake Fluids, and Brake Lines. Disc brakes were initially devised for use in sports car where highly reliable brakes were required however you can now find them in all cars.
Like every auto part your Toyota brakes are also prone to wear and tear. The main factors causing it are friction and heating of the brake parts. How to know your Toyota brake is due for maintenance and might need some replacement of brake parts?
- Air in the system: This is caused by air getting in the brake fluid area, usually from master cylinder. Due to wear and tear caliper piston rides far out of caliper and fluid starts depositing there. If there is air in the pedal it will appear malleable and may get pressed all the way to the floor. The standard way of dealing with such a thing is to perform an operation called "bleeding the blades." There are "bleeder screws" at each wheel cylinder and caliper for the same purpose.
- Hard Brake Pedals: Can be caused by non-functioning power boosters, faulty caliper pistons and caliper slides. Best way to repair it is rebuilt caliper and new pads.
- Brake squeal: You may hear a high frequency creak you may hear while going slow and not even applying the brakes. And the noise goes away when you apply the brakes. Such noise is generated from squealers or brake sensors. They are small springs attached to brake pads; when they get damaged these sensors start rubbing with the rotors leading to the noise. Best way is to fix this is changing the brake pads.
- Grinding Noise: This one is easiest to sort out. Check all four wheels and find out from which wheel you can hear the sound. Now raise that side of your car and provide it with some support. Unscrew the wheels and remove them. You will get the brake system consisting of brake pads, rotors, and caliper. Gently rotate the rotor back n forth until you identify the noise. Surface of rotor should be smooth if not then you need to replace them. Similarly if brake pads are worn out replace them too.
- Brake Pedal Pulsation: A brake pedal pulsates when your Toyota brake rotor is bent. To know whether it's the front or the rear wheels which is pulsating check pulsation on steering of your Toyota if you feel anything coming from steering then the problem is certainly on the rear wheels.
- Brake Grabbing: When you barely touch the brake pedal and one or more wheels get locked up or skid. It may happen because of the contaminated friction material on one or more wheels.
Driving safely is essential and brakes are vital to safety and security. In order to avoid risk and accidents always be regular with maintenance and upkeep of your Toyota. You may never get to replace the entire Toyota brake at once, its normally one part or other. Whenever replacing source only from an original part manufacturer and get the exact brake as per the model and year of your Toyota.
