4 Common Causes Of Brake Pedal Vibration And Ways To Fix!

Several questions arise in the mind, when a car shakes or vibrate. For instance, where does the noise or vibration appear to be coming from? Is it the steering wheel, brake pedal, or some other part of the vehicle that’s not working properly? Well, if the brake pedal shakes, then, it is potentially a serious issue which is simply making your vehicle unsafe to drive. There are ample of causes of brake pedal vibration. However, the solution is only to get the vehicle to nearest service station right away, for avoiding any further damage.

Brake Pedal Vibration: Causes And How To Fix

When the pressure is applied by foot on the brake pedal with optimum force, the system automatically strives to stop/slow the vehicle. It gives a nice firm feel while applying the pressure, however, sometimes the vibration in brake pedal occurs when this pedal is deployed.

This motion in brake varies from slight shaking to quite a severe shuddering, depending on the severity of the condition. So to your ease, here are certain roots causes explained, which may assist you in finding the main reasons for the “brake pedal vibrates when braking” question.

In fact, if the brake maintenance tips are followed then, these issues can also be kept at bay.

1. Brake Pad Issue

Each caliper of the wheel has two brake pads, with the friction surface of these pads confronting the rotor. So, when brakes are hydraulically applied (In simple words, brakes are made operational with liquid oil) then, the caliper squeezes the brake pads together onto the spinning rotor to stop the vehicle.

However, if pads are contaminated with oil, dirt, or other substance, then it causes brake pedal vibrates during the clamping of brake pads onto the rotor. Besides this, the wrapped, damaged, or excessively worn pads can also be one of the causes of brake pedal vibration.

How To Fix : You should dismantle the brake then clean it to remove all dust, rust and other pollutants. Getting rid of dirty things enable car brake to operate smoothier. In case that can not help, however, your last choice is replacement your pads. The cost of car brake pads vary from $35 to $150 for a complete set for one axle. It is higher for labor which costs from $100 to $300.

2. Brake Disc (Rotor)

The rotor part of the braking system is important. Therefore, it is critical to the overall safety of the vehicle that it is maintained properly. This spinning part of a wheel’s disc brake assembly works against the brake pads. Typically of grey iron color (a form of cast iron), the rotor functions to slow/stop the vehicle.

It is latched to wheel hub so this rotor spins in the direction of the wheel. When the brake is applied, the spinning rotor slows down the vehicle using friction from direct contact with the pads. Hence, bad rotor condition might causes brake pedal vibrates when stopping.

However, if this part of the system is scarred, cracked, warped or, rusted excessively then, it may cause an uneven grabbing of brakes, which can also produce squealing sounds or pulsating feel, when the brakes are applied.

How To Fix: Brake rotors need either resurfaced or replaced. Replacing or resurfacing both rotors (front set or rear set), even if only one of them is in bad condition, is crucial. New brake pads are highly recommended when replacing the rotors because worn surfaces of the pads will not make proper contact with new smooth rotors. It takes time for the surfaces of both parts to align properly, if you do not replace them in unison.

3. Improper Wheel Alignment

The aligned tires of the vehicle obey the steering wheel perfectly. On the contrary, when there is a disorganization of tires, they tend to produce squealing sounds. This unpleasant sound or vibration is caused by rubbing wheels against brake pads, when the vehicle is fastened or slowed-down.

Therefore, it must be dealt at an early stage before it worsens the functioning of the brake system.

How To Fix: For balancing issues, one indispensable process is wheel alignment. Applying an inspection will show which kind of alignment you need, a two or four wheel alignment. Commonly, a 4 wheel alignment is applied to SUVs while cars just need a 2 front wheel alignment. In case your rear axle is damaged, or the car frame itself, it is crucial to conduct a 4-wheel alignment.

4. Wear Out Components

Once the brake pads become thin or there is scarring or crack on the face of rotor then, getting the vehicle to nearest service station would help resolve the issue of vibrating pedal. Apart from these mentioned causes of brake pedal vibration, the worn out ball joints, tie rods, wheel bearings, and other parts of the system can also lead to brake problems.

How To Fix: This issue is the hardest one to solve because it takes time and many inspections to diagnose exact worn components. If you do not know much about engine or car, it is highly recommended that you should get a car suspension inspection to find out the cause of the brake pedal vibrations.

Wrapping Up

Knowing these causes can now possibly make you understand the warning signs of an unsafe brake system. So, whenever you experience such signs, get your vehicle right away to the service station.

    My toyota vitz 2005 model 2nd generation have a problem of brake failure.
    When I pressed hard the brake padle it’s touch the floor and start vibration and noise and don’t apply brakes.and when soft apply the brake it’s work perfectly and doesn’t have any vibration nor sounds. I recently changed the pads.
