How do you get rid of brake shudder?
Brake shudder is a common issue that many drivers experience, characterized by a vibration or pulsation felt through the brake pedal or steering wheel when braking. This problem can compromise your driving comfort and safety, so addressing it promptly is essential. At Kevin's Autos, with years of experience in car maintenance and repair, we’ve helped countless customers resolve brake shudder effectively. Here’s a detailed guide to understanding and fixing this issue.
What Causes Brake Shudder?
Brake shudder typically occurs due to uneven contact between the brake pads and the brake rotors. This uneven contact can result from several factors, including:
- Warped Brake Rotors: Excessive heat during braking can cause the rotors to warp, leading to uneven surfaces.
- Brake Pad Deposits: Uneven deposits of brake pad material on the rotor surface can create high and low spots, causing vibrations.
- Worn Suspension Components: Issues with suspension parts, such as bushings or ball joints, can amplify vibrations during braking.
- Improper Wheel Alignment: Misaligned wheels can contribute to uneven braking forces, resulting in shuddering.
Steps to Eliminate Brake Shudder
Follow these steps to diagnose and resolve brake shudder effectively:
- Inspect the Brake Rotors: Check for visible signs of warping or uneven wear on the rotors. If they are damaged, resurfacing or replacing them may be necessary.
- Examine the Brake Pads: Look for uneven wear or glazing on the brake pads. Replace them if they are excessively worn or damaged.
- Check for Brake Pad Deposits: Clean the rotors to remove any brake pad material buildup. Use a brake cleaner and a soft cloth or sandpaper for this task.
- Inspect Suspension Components: Ensure that suspension parts, such as control arms, bushings, and ball joints, are in good condition. Replace any worn components.
- Perform a Wheel Alignment: Misaligned wheels can exacerbate brake shudder. Have a professional perform a wheel alignment to ensure proper alignment.
- Bleed the Brake System: Air in the brake lines can cause uneven braking pressure. Bleed the brake system to remove any trapped air.
Preventing Brake Shudder in the Future
Prevention is always better than cure. Here are some tips to avoid brake shudder in the future:
- Use High-Quality Brake Components: Invest in high-quality brake pads and rotors to ensure durability and performance.
- Practice Proper Braking Techniques: Avoid hard braking whenever possible, as it generates excessive heat that can warp rotors.
- Regular Maintenance: Schedule regular brake inspections and maintenance to catch potential issues early.
- Allow Brakes to Cool: After heavy braking, allow your brakes to cool down before parking to prevent heat-related damage.

Frequently Asked Questions
How do you fix juddering brakes?
THE SOLUTION: Replace the discs and make sure the tightening torque isn't overly severe. Look for distortion of the hub itself, as it is possible for hubs to warp. Bolting a disc to a warped hub will lead to brake judder when braking.
How do you fix a shudder on a car?
Unbalanced Tires
If your tires are not evenly weighted, it can cause your car to shake at various speeds, especially noticeable when accelerating. Getting your tires balanced by a professional ensures even distribution of weight around the wheel, rectifying the imbalance and smoothing out your ride.
Is it okay to drive with a brake shudder?
Driving downhill with a shaking brake system can increase the risk of losing control of the vehicle, especially on steep grades. It's advisable to have the vehicle inspected by a qualified mechanic as soon as possible to diagnose and resolve the issue.
What causes a car to shudder when braking?
If the brake rotors are out of balance or warped, the vehicle can jerk to a stop or rapidly vibrate depending on your driving conditions. If the brake pads are worn or filled with dirt and debris, the area of the rotor under the brake pads can collect these substances, causing the car to pulsate when braking.
How to tell if calipers are bad?
Some signs that your vehicle may have a bad brake caliper can include abnormal noise, reduced braking ability, fluid leaks, or the feeling that your vehicle is pulling to one side. Unlike brake pads that should be replaced consistently, calipers ought to last with the vehicle.
Can alignment cause brake shudder?
Unevenly work or misaligned tires can, thus, cause a car to shake when braking. Sometimes, tires will only require alignment or another service like tire rotation. Other times, you may need new tires. Tire alignment is usually checked during a routine tire rotation, which should be performed every 5,000 to 7,500 miles.
How do you fix a stuttering brake?
THE SOLUTION:
If there's only minimal DTV, it may be sufficient to remove the deposits using a brush or sandpaper and road test the brakes. If this has not realigned the surfaces, the only solution is to replace the brake pads and rotors.
How much does it cost to fix a brake judder?
New pads on worn rotors can create issues with the new pads, cause vibration, or make braking less safe. So, plan to purchase new pads and new rotors together. Each aftermarket rotor costs an average of $30 to $75. Labor to service brakes can run from $90 to $200 per hour.
How do I stop my brakes from shuddering?
How to fix brake shudder. If a brake disc develops DTV (disc thickness variation), the disc needs to either be machined to iron out the flat spots or replaced completely depending on the condition of the disc. Brake calipers that aren't working the way that they're supposed to can also contribute to brake shudder.
How much does it cost to fix a brake shudder?
Depending on the reason for the brake shudder, pricing to get this fixed will vary greatly. If it's a quick hub clean or un-seizing a caliper pin, that will start from $50. If eliminating the problem means machining the rotors, pricing will start from $90.
