Why does my Chevy shake when I brake?

The most common reasons are warped or worn brake rotors and tire/wheel issues. Other brake or suspension problems can also cause braking vibrations, so a prompt inspection is important for safety and proper repair.

Braking-induced shaking on a Chevy can stem from several linked systems—brakes, wheels and tires, and suspension. This article breaks down the typical causes, how to diagnose them safely, and when to seek professional help.

Common causes by system

Here are the most frequent sources of braking vibration, organized by the system they affect. Start with these when you notice a shake during braking.

• Warped or uneven brake rotors (front rotors are most commonly affected), which can cause a pulsing brake pedal and steering wheel vibration.


• Worn, glazed, or unevenly worn brake pads that don’t grip the rotor uniformly.


• Sticking, seized, or dragging calipers that keep the rotor partially engaged as you slow down.


• Unbalanced wheels or damaged tires (out-of-round, belt separation, or uneven wear) that transmit vibration when braking.


• Damaged or bent wheels causing rotor runout and uneven contact with the brake surface.

Rotors, pads, calipers, wheels, and tires are the usual suspects when vibration starts with braking, but the symptom can involve other linked components as well. Identifying the exact combination is key to a proper repair.

Other contributing factors

In some Chevy models, braking vibration can be influenced by suspension or steering wear, tire condition, or ABS-related symptoms. The following factors can amplify or mimic braking shake.

• Suspension wear: worn ball joints, tie rods, control arms, or bushings can transmit motion that becomes noticeable when braking.


• Wheel bearings or a loose hub can produce vibration that worsens under braking.


• Tire problems: improper inflation, misalignment, or tires with unusual wear patterns can cause vibration during deceleration.


• ABS-related issues: faulty sensors or an actuator can cause pulsing if the ABS engages unexpectedly during braking.

Because many of these items require specialized tools to diagnose, confirming the root cause usually involves a professional inspection that includes road testing and component measurements.

What to do now: safe diagnostic steps

Take these safe, information-gathering steps to better describe the issue to a technician. Do not attempt disassembly of braking components unless you’re trained and equipped for it.

• Check tire pressure on all four tires and inspect tires for visible damage, cupping, or uneven wear. Inflate to the vehicle’s recommended pressures (found on the door placard or owner’s manual).


• Inspect wheels for bends, cracks, or visible runout. If a wheel looks damaged, avoid driving long distances and have it evaluated first.


• Note when the vibration occurs (speed range, light vs. heavy braking, straight-line vs. during turns) and whether you hear grinding, squealing, or feel a pulsing in the brake pedal or steering wheel.


• Assess brake pedal feel: a pulsing pedal often points to rotor warp; a soft or spongy pedal can indicate air in the brake lines or a hydraulic issue.

Sharing these details with a technician helps them pinpoint whether the issue is brake-related, wheel-related, or a combination of both.

When to see a mechanic

Arrange service promptly if you notice vibration that worsens, a drop in braking performance, or any unusual noises or smells. Braking problems can become safety risks in wet or icy conditions.

• Immediate danger signs: brake pedal goes to the floor, brake warning light illuminates, or you hear grinding.


• Ongoing symptoms: vibration that persists after tire/wheel checks or appears only after certain driving conditions should be inspected sooner rather than later.

A technician will typically perform a road test, inspect rotors, pads, calipers, wheel bearings, brakes lines, suspension, and tires, and measure rotor thickness and runout. Replacing warped rotors, resurfacing or replacing pads, and balancing wheels are common fixes when applicable.

Preventive maintenance tips

Regular maintenance helps prevent braking shake and keeps braking performance consistent. Consider these practices as part of Chevy upkeep.

• Have brakes inspected at least once a year or whenever you notice vibration, noise, or reduced braking performance.


• Rotate and balance tires regularly; replace tires when wear is uneven or excessive.


• Maintain proper tire pressure and watch for changes that could indicate a slow leak.


• Keep brake fluid at the correct level and check for leaks or signs of brake line wear.

Proactive maintenance reduces the likelihood of vibration during braking and helps ensure safe, reliable stopping power across your Chevy lineup.

Summary

Braking-induced shake in a Chevrolet is most commonly tied to warped rotors or tire/wheel issues, but it can involve calipers, wheel bearings, suspension, or ABS. Start with a tire and wheel check, then have the braking components inspected. Prompt diagnosis and repair help maintain braking performance and overall safety on the road.

What is the Chevy shake issue?

The "Chevy Shake" is a term for a violent shaking or vibration issue experienced by drivers of certain Chevrolet and GMC trucks, particularly Silverados and Sierras from model years 2015-2019. It is often linked to problems with the vehicle's 8-speed automatic transmission, with symptoms including shuddering in higher gears and hesitation or lurching in lower gears. The issue can also be caused by other factors like defective aluminum driveshafts, or by a failure to properly balance certain Chevy wheels on tire balancing machines.
 
Symptoms

• A violent shaking or vibration that can be felt in the steering wheel, seat, and dash.
• Shuddering specifically in higher gears.
• Hesitation or lurching in lower gears.
• The vibration can be so intense it affects vehicle control. 

Potential causes

• 8-speed transmission issues: The 8L45 and 8L90 transmissions used in certain 2015-2019 models are a primary focus of lawsuits and complaints. 
• Defective aluminum driveshafts: Some legal complaints have also pointed to issues with the aluminum driveshaft. 
• Tire and wheel balancing: In some cases, the problem was traced back to incorrect wheel balancing on machines that did not have the proper cones for Chevy wheels, leading to the wheels not being held correctly. 

What has been tried to fix it

• Transmission fluid flushes
• Replacing torque converters, transmission filters, and fluid
• Replacing the valve body, cooler lines, and transmission pan
• Replacing tires, rims, and brake rotors
• Performing alignments
• Replacing springs, shocks, and struts
• Replacing axles and ring and pinion sets
• Adding weight to the rear of the truck 

Legal action

• Because of the widespread nature of the problem, multiple class-action lawsuits have been filed against GM. 
• A recent appellate court ruling has decertified some of these lawsuits, but legal avenues for recourse may still exist, especially if damages or accidents are involved. 

How do I fix my car shaking when I brake?

A car shaking when braking is most often caused by warped brake rotors. To fix this, you can either have the rotors resurfaced (machined to be smooth again) or replaced if they are too thin. It's also crucial to replace the brake pads when you resurface or replace the rotors. Other less common causes include worn tires, damaged suspension components, or a bad wheel hub, which may require a professional diagnosis. 
Potential solutions
For warped rotors

• Resurface the rotors: A machine shop can shave a thin layer off the rotors to make them smooth and true again. 
• Replace the rotors: If the rotors are worn too thin (below the discard thickness), they must be replaced. 
• Replace the pads: Always replace the brake pads at the same time as the rotors, whether you are resurfacing or replacing them, because uneven wear on the pads is often the root cause of the rotor warping. 

For other issues

• Check your tires: Worn or unevenly worn tires can cause shaking. Have your tires rotated and your alignment checked regularly, and replace them if they are old or damaged. 
• Inspect suspension and wheel hub: Worn or loose suspension parts or a bad wheel hub can also contribute to vibrations when braking. If your steering wheel still shakes after addressing the brakes, these are the next things to inspect. 
• See a professional: If the shaking is severe, or you aren't comfortable with brake work, take your car to a professional mechanic for diagnosis and repair. 

To prevent future shaking

• Avoid riding the brakes, especially on long descents. 
• Avoid sudden, repeated braking, as this can overheat rotors. 
• Have your brakes and tires inspected regularly as part of your vehicle's maintenance.

This video explains common reasons for your car shaking when braking, especially warped brake rotors: 26sOne Trick TechnicianYouTube · Dec 28, 2024
Primary causes

• Warped brake rotors: This is the most frequent reason for shaking. The rotors can warp from excessive heat generated during braking, causing them to have an uneven surface. When the brake pads clamp down, this unevenness creates a pulsating or shaking sensation. 
• Worn brake pads: As brake pads wear down, the material becomes thinner and can cause uneven wear on the rotors, leading to vibration. You might also hear a squeaking sound when you brake if the pads are due for a replacement. 
• Stuck brake calipers: If a brake caliper is stuck, it can prevent proper contact with the rotor and cause vibrations.

Other potential causes

• Unbalanced tires or suspension issues: Worn or unbalanced tires can also contribute to shaking while braking. Other suspension components, like a bad wheel bearing or loose suspension parts, can also be the culprit. 
• Brake drums: In vehicles with drum brakes, wear or damage to the brake drums can cause shaking. 
• Improper brake work: Shaking can result from new brake pads not being properly bedded in or from rotors that were not installed correctly.
