Some vehicles exhibit brake-related issues such as brake noise, brake judder, or brake dragging. If you experience any of these symptoms, it’s important to seek a professional mechanic in Towson, MD to inspect your vehicle’s brake system. An experienced ASE-certified technician can diagnose the specific brake problem causing the concerning sensation and recommend the proper brake repair or brake service.

Braking Noises

There are various types of brake noise and many different conditions that can cause noise. Frictional coefficient between brake pads and rotors varies depending on pad material, temperature, humidity, braking force, etc. During braking, the brake pads are pressed with great force against the brake rotor. This generates friction to bring the vehicle to a stop.

If the brake pads are of a soft compound, a more substantial amount of brake dust will appear on the wheels, and the pads will wear more rapidly, but there will be less chance of brake noise.

If the brake pads are of a hard compound (as used in high-performance applications), less brake dust will appear, the pads will last longer, and braking performance will be improved.

Finding a stable compound with the qualities of both hard and soft compounds is difficult.

Squeak or Groan Noise

If you hear a brake squeak or groaning noise when applying the brakes, the brake pad material may be the cause. New brake pads that are overheated before being properly broken in can become glazed, leading to noise and reduced braking performance.

In some cases, scuffing the friction material may reduce glazing. If the brake pads no longer have sufficient thickness, a brake pad replacement is required to restore proper braking function.

Rattle or Clunk Noise

If a rattle or clunk noise is present, the technician will inspect and replace the brake pad shims and mounting hardware. If the brake pad assembly has excessive clearance and too much adjustment or shimming is required it may be necessary to replace the brake pad set.

The ASE professional brake technicians at Hollenshade’s in Towson will inspect the brake rotors and remove old pad material deposits when possible. The high-grade synthetic lubricant will be applied to the brake pad backing plate to further reduce vibration and noise.

Brake Dragging Noise

If the noise is due to a brake dragging, you should seek an experienced mechanic to diagnose the source of the issue. The professionals at Hollenshade’s will inspect the brake calipers and sliders to ensure they are not seized. If seized caliper slide pin(s) are found, they are appropriately removed in a manner that preserves their structural integrity and that of the brake caliper bracket. The caliper slide pin(s) are always cleaned and lubricated with every brake service at Hollenshade’s. The mechanics at Hollenshade’s will also evaluate the brake hydraulic system hoses and lines. An experienced mechanic will feel the condition of the caliper piston when returned during brake service. If excessive resistance is felt the technician will check the caliper piston boot for cracks, breakage, or poor sealing and possible water entry into the caliper piston cavity. A dragging brake pad will cause excessive heat and may warp the brake rotor. In extreme cases, excessive heat can damage the wheel bearing.

Brake Judder

Brake judder, sometimes referred to as brake rotor warping, is caused by uneven brake rotor thickness or run-out. As the brakes are applied, the clearance between the brake pads and rotor varies, creating vibration.

These vibrations travel through the brake hydraulic system, suspension, and steering components, and may be felt through the brake pedal, steering wheel, or vehicle floor. Even microscopic variations in rotor thickness can cause noticeable judder, especially when slowing from higher speeds.

Brake Judder Potential Repairs

The brake rotor will need to be replaced if the unevenness (run-out) is significant enough that resurfacing it will reduce the minimum thickness of the rotor past the manufacturer’s stated minimum.

Excessive heat damage will need to the rotor or pad (heat cracking) will require it’s replacement.

Significant rust and corrosion on the brake rotor, rotor hat, or cooling fins are also signs the brake rotor should be replaced during repairs and service.

 

If you are experiencing brake vibration or judder again after having the brake rotors replaced you should discuss braking/driving habits and vehicle storage patterns with your trusted mechanic. You should also seek an experienced facility like Hollenshade’s in Towson to inspect the other components that can affect braking performance including the wheel bearings, hubs, and tires.

Frequently Asked Questions About Brake Repair in Towson, MD

What causes brake noise in my car?

Brake noise can be caused by several issues, including worn brake pads, glazed pads, loose brake hardware, rotor surface irregularities, or seized caliper components. Squealing, grinding, rattling, or clunking noises are all signs that you should schedule a brake inspection with a Towson mechanic as soon as possible.

Is it safe to drive with noisy brakes?

Driving with noisy brakes is not recommended. While some brake noise may be minor, it can also indicate serious problems such as metal-to-metal contact, seized calipers, or damaged rotors. Continuing to drive may lead to brake failure, higher repair costs, or unsafe stopping distances. A professional brake repair shop in Towson, MD can determine the cause quickly.

What is brake judder and why does my car vibrate when braking?

Brake judder is a vibration felt through the brake pedal, steering wheel, or vehicle floor during braking. It is commonly caused by uneven brake rotor thickness (run-out), excessive heat damage, or corrosion on the rotors. Brake judder is especially noticeable when slowing down from higher speeds and should be addressed by a qualified Towson brake repair specialist.

Can seized brake calipers cause brake dragging?

Yes. Seized brake calipers or stuck caliper slide pins are one of the most common causes of brake dragging. When calipers fail to release properly, brake pads remain in contact with the rotor, generating excessive heat. This can lead to warped rotors, premature brake wear, and even wheel bearing damage. Brake dragging should be diagnosed immediately by a Towson auto repair shop.

How do I know if I need new brake pads or rotors?

Common signs you may need brake pad or rotor replacement include:

• Squealing, grinding, or groaning noises
• Vibrations or shaking while braking
• Longer stopping distances
• Brake warning lights
• Visible thinning of brake pads

A professional brake inspection in Towson, MD is the best way to determine the condition of your braking system.

Why do my brakes make noise after being replaced?

Brake noise after replacement can occur if pads were not properly broken in, if inferior materials were used, or if brake hardware was not correctly lubricated or installed. In some cases, driving habits or rotor surface conditions can contribute. An experienced Towson mechanic can inspect the system and make adjustments to eliminate the noise.
