Surging brakes mean there is an issue. If you step on the brake and the pulsation is minor in your steering wheel and seat, then you may not have to worry about it. Sometimes the brake pulsation can be out of control, and once you step on the brake, the car vigorously shakes.
This can lead to a much more difficult situation. Excessive pulsation of the brakes can be a safety concern especially during slippery road conditions. The reason why your brake is pulsating is that that brake calipers are unable to grab hold of the rotor. This can cause a slipping or sliding predicament.
Fixing the Problem
The first step towards fixing the pulsating brake issue is determining the cause of the pulsation. It is worth noting that a surging or pulsating brake can stem from plenty of different causes. One of the most common causes of pulsation is warped rotors. Rotors are components that undergo plenty of friction and heat since the brake pads press upon their surface whenever you step down on the brakes.
For this reason, you can experience minor tremors in either the steering wheel or from under your car seat if you have been practicing particular driving habits. These driving habits pertain to jamming the brakes too hard. However, a person can be forced to do this if they are driving during inner city rush hours, or even at a steep slope.
Excessive and forced braking will ultimately cause wear on the rotors, which will lead to damaged rotor surface. However, this is not the only way a car’s rotor will undergo stress due to braking friction. Once you have determined the particular issue that is causing the friction, then you must correct that issue.
Solutions for Surging Brakes
If you find that the pulsating tires is only because of warped rotors, you need to make sure that you are replacing the rotors with the pads. This is regardless of what conditions the pads were in, even if they are brand new. The reason for that is that the surface of the pad needs to come in contact with the surface of the rotor.
If you decide to cut costs and only replace the rotors, you will end up experiencing brake noises and a pulsating effect as well. The rotors that you find today consist of much thinner material and people try to keep them at a very minimum specification, which helps keep the vehicle lighter and is also more fuel efficient overall.
Cutting the rotor’s thickness will present issues. By the time you dig into where the metal is good, the rotor will become very thin. This would not be good if you have very thin brake rotors. They are not going to be able to dissipate the heat overall and the brakes will not function as they should.
You should not confuse a brake pulsation with any other problems. Some people confuse with ABS unit activation. You have to therefore know how to identify brake pulsations.
