Diagnosing any brake issues is important. Before you can dive deep into diagnosis, you must be wary of the many signs that point to Braking system malfunction. The most common one includes the decrease in braking ability. This means, that you should be wary once you start noticing that the car is not responding the same way it uses to when you press on the breaks. Another indication involves a spongy break. This means that you have to press the breaks deeper than normal for the car to stop. Diagnosing the brakes can help improve the safety for your vehicle.
Diagnosing a Spongy Brake Pedal
With a spongy brake pedal, you must check a couple of things instantly before you start replacing brake pads. You must keep a check on the fluid levels in your master cylinder at first once you find that the brake pedal is spongy.
Checking the brake fluid is easy, all you have to do is look for the fluid cap inside the engine, and it should have an indicator that alarms you when the brake fluid is low. If the brake fluid inside your car is not at an optimum level, then, you will benefit from pouring in more fluid inside the engine.
The reason why your car can be low on brake fluid could be indicative of a leak. To check whether that is true, you can start pumping the brakes after you fill up the master cylinder and try to observe any kind of a leak. If you find drops of brake fluid leaking from the engine, this can mean that you have to take your car to a proper technician.
If there is no leak in the car, then this can mean that your disc pads have wear, and need replacement. Overall, the lowering of the brake fluid inside cars is often a sign of other faulty issues with the braking system.
Testing the Power Assist
The way you can test the power assist is simple, to start, you have to press the brake pedal with all your force, keeping the engine off. You must press the brakes with full pressure several times with the engine shut down.
By doing so, ensure that the brake pedal is firm and stopping at the same position each time. If this does not happen, it indicates a major problem. Once you do that, hold the pedal at full extension and then start the engine. If the pedal goes down slightly and then stops firmly, this means that your braking system is working optimally.
There is plenty more to keep in mind when it comes to braking system diagnosis, however, checking the brake fluids, brake pads, and testing the power assist should be enough to keep you secure. These measures are essential as they can keep you alive on the road.
