Why Do Car Brakes Fail?
Failing car brakes are not something we should take lightly; if you are unsure of the state of your vehicles brakes, or you suspect they may be in the process of failing, it is always good practice to have them see to by a professional fitment centre (LINK) sooner rather than later.
However, if your car brakes repair seem to be going along well, and fail without prior warning, there could be more than meets the eye with this problem.
What Are The Causes of Brake Failure?
- Loss Of Brake Fluid Pressure
“The braking system in a vehicle works with hydraulic pressure. If there is any type of leak in the brake line, caliper or wheel cylinder, there could be insufficient pressure in the brake line for the brakes to work properly. When a vehicle has a serious leak in its brake line, a warning light should come on in the vehicle. This could indicate a loss of fluid pressure in the brake system. A vehicle in this condition is unsafe to drive. A professional mechanic will know how to properly inspect a vehicle’s brake system to detect any leaks and repair them.”
- Air Pressure
“When a person presses the brake pedal, and it goes all the way to the floor, the air pressure in the brake line could be the problem. When a person presses a vehicle’s foot brake, air is used, and it must build up quickly. If the pressure drops too low when driving, the vehicle should no longer be driven. This situation can become dangerous no matter what speed a vehicle is traveling.”
- Brake Line
“A rusty steel brake line is something that can be found in older vehicles. In Toledo OH, this can happen since older vehicles have been exposed to years of moisture as well as road salt. If the corrosion coating on an older vehicle’s steel brake lines is thin, or not of good quality, salt can easily corrode it. Once the line rusts, brake failure can occur as brake fluid can begin to leak.”
- ABS Modulator
“This could be faulty if it is causing brake pressure to leak internally. This will result in an insufficient amount of routing pressure being sent to the brakes when the driver steps on the pedal. It’s possible for rust or dirt in a vehicle’s brake system to get into its ABS modulator. This will make it difficult for its spring-loaded accumulator valve to close properly. When this happens, the ABS modular can have an internal leak.”
- Power Brake Booster
“When a vehicle has a faulty power brake booster, the driver has to press the brake pedal to the floor for it to work. The car can be driven for a very short distance before repairs are necessary. Most of the brake boosters found in current vehicles are vacuum controlled. Checking and repairing a brake booster will require a professional mechanic to use a vacuum measurement tool to detect and solve any problems.”
- Water In Brake Fluid
“When brake fluid reaches a high temperature, water will vaporize. It will cause steam to be compressed, and it doesn’t react like water. The braking motion will not be transmitted to the vehicle’s wheels. It will be dissipated, and the vehicle will not be able to brake.”
