Is The Brake Pad In Your Car Sticking?
The brake pad is possibly getting stuck because the caliper piston is damaged and can’t release. However, it might also be that an oil leak is causing the brakes to become oil-soaked and sticky. Alternatively, faulty sensors, collapsed brake hoses, stuck parking brake cables, or a failing ABS module might be the culprits.
If your car's brake pad is partially stuck, it might cause uneven braking and compromise your safety on the road. Therefore, taking action and identifying the cause of any brake-related issue is crucial to avoid dangerous consequences.
To prevent the problem from escalating and affecting parts like the rear brakes, consider talking with a qualified technician with expertise in brake systems. They can diagnose and fix the issue promptly, helping you avoid costly repairs and ensure your vehicle's integrity.
Regular brake maintenance and vehicle health inspections are essential for preventing issues like these from occurring. Remember, your safety on the road should always be a top priority, so don't hesitate to seek help if you notice any issues with your brakes.
Let's Get To The Bottom Of It!

The brake hose is a rubber tube that helps the brake fluid to move through to the brake calipers. It's a bit like a straw that lets the fluid travel to where it's needed. Over time, the inside of the hose can break down and cause a blockage. It's like when a straw gets clogged, and you can't get any liquid through it. This blockage can turn into a one-way valve, which means that when you apply the brake pressure, the fluid can get through the hose, but when you release the brake, the blockage stops the fluid from flowing back the other way. This can make your car pull to one side when you're driving

The brake caliper is vital to your car's braking system. Another essential part of this system, a piston, moves in and out to push the brake pads against the brake rotor, making the car brake. This process is powered by pressurizing brake fluid. To protect the piston, a piston boot removes dirt and water. However, water can enter the caliper if the boot gets torn, causing rust. If this happens, the piston gets partially stuck and gently engages the pads. This can make the brake pads heat up so much that they start smoking.

The brake pads are like cushions that help your car stop. They sit inside a brake saddle, like a little seat on which the pads rest. When you press the brake pedal, it makes the caliper - which is like a clamp that squeezes the pads - pull back. A rubber ring called an o-ring helps the brake fluid do its job. Usually, when you release the brake pedal, the pads release from the brake rotor (which is like a metal disk that the pads press against). But if there's dirt or rust in the slides where the pads sit, the pads can get stuck and not move away from the rotor. When this happens, you might hear a humming noise from your brakes. This noise is more noticeable at higher speeds.

The axle seal helps keep the gear oil inside the axle. This action ensures that things run smoothly. However, since it's made of rubber, it can wear out over time and start to leak. If this happens, oil can seep onto the brake pads, making them sticky. Consequently, the brakes stick to the wheels even after you take your foot off the brake pedal, making driving harder and damaging your vehicle.

The wheel speed sensor tells the anti-lock brake module how fast each wheel turns. If one wheel spins faster or slower than the others, the anti-lock brake system applies the brakes to keep the vehicle stable and prevent skidding. However, if one of the wheel speed sensors is broken or not working correctly, the anti-lock brake system can activate without necessity, causing the brakes to drag and impact the car's handling.

The ABS module is like an intelligent computer that helps control your brakes to keep the system safe. It regulates the wheels by stopping or accelerating them to ensure they spin at the same rates. If it's not working right, especially in bad driving conditions, the brakes can lock up, and you might lose control of the car. When there's a problem with the ABS module, you'll see lights on your dashboard that say "ABS" and "Check Engine."

Explore the following typical inspection results that show a potential cause for the symptom and select the one you believe is similar to your vehicle's issue.
Collapsed brake hose
Leaking axle seal
Faulty wheel speed sensor
Faulty abs module
Stuck brake pad
Stuck brake caliper piston
The proof image shows a cutaway of the collapsed brake line, causing the restriction.
A customer brought their vehicle because it was pulling to the right, so they thought they needed an alignment. During a test drive, the technician confirmed the pulling, which became more noticeable after a few stops. However, when pressing the brakes, the pull went away.
During a vehicle health inspection, the technician saw that the right front brakes seemed slightly applied, and the front right brake pads were thinner than the left. The technician then investigated the tightness of the right front wheel when spinning; while doing so, they found the brake pads still applied.
They loosened the screw on the right front caliper, and the wheel spun freely. However, the pads were still clamping. This proved that the brake hose was causing the restriction, and because all the brake lines were similarly worn, the technician recommended replacing all four brake hoses.
Due to the uneven wear on the front brake pads, the technician also recommends replacing the front brake pads and the rotors due to the hot spots on the rotors. In addition, the technician noted that the hot spots were likely caused by the brakes being applied for an extended period, which would also cause the thinner brake pads.
1/6
The proof image confirms that the brake pads were sticky due to oil contamination, and this is what caused them to drag, causing a pull to the right. In addition, the red arrow points to the oil on the brake pads, making them stickier.
A customer brought their vehicle to the shop and reported the brakes felt dragging. In addition, they noticed a slight pull to the right and pointed out a mark on the inside of the right rear tire.
During the test drive, the technician noticed the brakes released too slowly. Additionally, they confirmed a pull to the right. When braking aggressively, the right rear tire would lock up, and the ABS would activate.
During the vehicle health inspection, the technician found a leak in the right rear axle seal; the right rear brake pads were oil-soaked. Upon disassembling the brakes, the technician confirmed the oil made the system sticky and draggy.
Therefore, the technician recommends replacing the right rear axle seal, replacing the rear brake pads, and turning the rotors since they are still within the manufacturer's specifications.
2/6
The proof image shows the broken wire in the wiring harness leading to the left front wheel speed sensor. This was causing the ABS to engage unnecessarily and creating the issues that the customer was experiencing.
A customer brought their vehicle to the shop and mentioned the brake pedal felt funny sometimes. They also heard a growling noise from the dash.
During the test drive, the technician noticed the ABS module engaging when it shouldn't. Plus, the dashboard had ABS, traction control, and check engine lights.
During the vehicle health inspection, the technician did a code scan and found a fault with the left front wheel speed sensor. The customer authorized an additional cost for diagnostics, and the technician used a vehicle-specific scanner to verify the code.
The technician lifted the vehicle and had an assistant spin the wheels individually while watching live data on the scanner. They found that all wheels emitted an expected signal except for the left front wheel.
When the technician tried to unhook the wheel speed sensor connector to test it, they found broken wiring harnesses.
The technician recommended replacing the pigtail going in the speed sensor, and retesting. This should solve the issue and prevent the ABS from engaging when it's not supposed to.
3/6
The proof image provided shows both the ABS and check engine lights illuminated, confirming the customer's report of the warning lights being on.
A customer brought in their vehicle and reported they almost rolled it during a panic stop; the road was wet. Plus, they mentioned the ABS and check engine light had been on for about two months.
During the test drive, the technician verified that the dashboard had all the warning lights the customer mentioned. Plus, they found that the vehicle's wheels would lock up and slide on loose gravel when panic stopped, confirming the customer's concern.
During the vehicle health inspection, the technician found a vehicle code scan indicating lost communication with the anti-lock brake system. After obtaining authorization for additional diagnostics, the technician used a vehicle-specific scanner, confirming a communication issue with the ABS module.
The technician then accessed the ABS module and verified that power and ground were going to the module, indicating that the module had failed. The technician recommended replacing the ABS module and retesting the vehicle to ensure that the issue had been resolved.
4/6
The proof image shows that the rust in the brake pad slides caused hot spots and the humming noise. Essentially, rust built up on the brake pad slides, causing the brake pads to stick and creating friction that resulted in hot spots on the rotors.
A customer brought in their vehicle and reported hearing a humming or switching noise that got louder as they went faster; the noise appeared from the vehicle's front side.
During a test drive, the technician heard a noise that sounded like the brakes were dragging; it almost seemed like the emergency brake was applied.
During a vehicle health inspection, the technician found hot spots in the front rotors and extremely rusty front brake pads and slides. However, they found no issues with the caliper boots and pistons.
However, when the technician tried to slide the brake pads back and forth manually, they were almost frozen due to rust. This resulted in worn brake discs.
Due to the number of hot spots on the rotor and the pads' thinness, the technician recommends replacing the pad hardware, the front brake pads, and the rotors.
5/6
The proof image shows the torn brake piston boot that allowed water to rust the caliper bore, causing the piston to stick. This can develop into caliper slide pins problems.
The customer noticed a hot smell and saw smoke coming out of the right front wheel of their vehicle. They also mentioned that the steering wheel vibrated a bit, resulting in the car pulling to one side.
To investigate this issue, a technician did a test drive and observed the vehicle was pulling to the right. Interestingly, when applying the brakes, the pulling went away. This meant something wrong with the vehicle's braking system.
During the vehicle health inspection, the technician noticed that the right front brake pads were thinner than the left and had definite heat spots. In addition, the technician suspected the right front caliper was sticking due to the torn piston boot and rust.
The technician tried to manually engage the piston to confirm this suspicion, but it was stuck. Due to the number of heat spots on the rotor and the thinness of the pads, the technician recommended replacing both front rotors, brake calipers, and pads; they also recommended a brake system flush.
