Dirty brake rotors
After changing the brake pads, dirty brake rotors can cause the car to shake. Dirt, rust, and debris can build up on the surface of the rotors, generating uneven contact between the brake pads and the rotors and causing vibrations. In some situations, brake rotors can get glazed or overheated, worsening the problem.
Dirty brake rotors may be repaired by meticulously cleaning them, which can be done by a professional or yourself.
- To clean the brake rotors, your vehicle should be hoisted on jack stands and the wheels removed.
- Once the wheels have been removed, the mechanic or you yourself can use brake cleaner, sandpaper, or a wire brush to remove any dirt, rust, or debris from the rotor’s surface.
If the brake rotors are significantly damaged, deformed, or overheated, they may need to be resurfaced or replaced, necessitating a specialist’s assistance.
Resurfacing entails removing a tiny portion of the rotor’s surface to smooth it out, whereas replacement entails inserting new rotors. Repair costs vary based on the severity of the damage and the type of repair required, with replacement often costing more than resurfacing.
Ignoring filthy brake rotors can decrease braking performance, which can be hazardous and increase the likelihood of an accident. As a result, it’s critical to address the problem as soon as possible to ensure safe and pleasant driving.
Warped Rotor from Factory
A warped rotor happens when the rotor (the metal disc against which the brake pads press to slow the car) becomes uneven owing to overheating or uneven wear. When the brakes are engaged, the car may shake or tremble.
Here are some suggestions for repairing a warped brake rotor:
- Turn off your automobile and park it in a secure place.
- Take off the wheel cover and the tire from the rim.
- Place a piece of wood between the rotor and the hub to prevent damage to either item.
- Examine each blade for warping or bent edges.
- Replace the blade which you suspect for having bent edges.
Wheel Bearing Loose
A wheel bearing is a series of steel balls or rollers that hold the wheel in place and allow it to revolve smoothly on the axle. A loose or worn out wheel bearing can cause your automobile to tremor or wobble, especially at high speeds.
When a wheel bearing becomes loose, it causes the wheel to wobble and vibrate. This vibration is frequently felt in the steering wheel, making driving difficult. A loose wheel bearing can cause the wheel to fall off the vehicle severely, resulting in a difficult situation.
To repair a loose wheel bearing, follow these steps:
- Using a jack, raise the vehicle off the ground and secure it with jack stands.
- Remove the problematic wheel’s wheel and tire assembly.
- Remove the wheel hub assembly’s braking caliper and rotor.
- Remove the axle nut and washer from the axle shaft’s end.
- Remove the steering knuckle’s wheel hub assembly.
- Replace the old wheel bearing in the hub assembly with a new one.
- In reverse order, reassemble the wheel hub assembly, axle shaft, rotor, and brake caliper.
- To the manufacturer’s specifications, tighten the axle nut.
- If necessary, repeat the procedure for the remaining wheel bearings.
- Drive the car to confirm that the vibration is gone.
Dirty Hub or Flange
Before fitting the replacement rotor, the hub or flange against which the brake rotor is placed must be properly cleaned. Rust frequently accumulates on the flange. The rust gets disturbed when the old rotor is removed.
If the machined faces of the hub and rotor are not thoroughly cleaned, they will not sit flat with each other. Clean the hub with a wire brush or emery paper until it is smooth to the touch.
Incorrectly Seated Brake Pads
If the new brake pads are not correctly seated, the power supplied to the brake pedal and onto the caliper will be uneven. As a result, braking performance and shaking will deteriorate. This vibration is produced by incorrectly placed brake pads in the caliper.
Always keep your hands clean when installing brake pads. Make that the pads are evenly pushed on both sides of the rotor.
Loose Brake Caliper
A brake caliper is a disc braking system component that contains the brake pads and exerts pressure on them to slow or stop the vehicle. When a brake caliper is loose, the brake pads shake against the rotor, causing a visible vibration in the automobile.

A sloppy brake caliper can also create uneven wear on the brake pads and rotor, shortening their lifespan and potentially resulting in brake failure. Resolving this issue as quickly as possible is critical to guarantee your and others’ safety on the road.
To repair a loose brake caliper, follow these steps:
- Carefully remove the brake caliper bolts.
- Examine the bolts and bolt holes on the spindle critically for rust or corrosion.
- Retread the bolt hole using a thread cleaner or chaser.
- Install the brake system.
- Ensure the recommended torque pressure when tightening the caliper bolts.
Brake Caliper Sticking
A squeaking brake caliper might create vibration in your vehicle. A brake caliper is a disc braking system component that contains the brake pads and exerts pressure on them to slow or stop the vehicle. When a brake caliper becomes stuck, the brake pads can scrape against the rotor, causing friction and heat. This can cause uneven wear on the brake pads and rotors, shortening their lifespan and causing the car to shake or pull to one side when braking.
You can fix a stuck brake caliper by doing the following:
- Using a jack, raise the vehicle off the ground and secure it with jack stands.
- Remove the problematic wheel’s wheel and tire assembly.
- Examine the brake caliper for damage or wear after removing it from the rotor.
- Examine the brake pads for uniform wear and thickness. Replace them with new ones if they are uneven or damaged.
- Inspect the caliper piston and guide pins for wear and damage. Replace them with new ones if they are broken or worn.
- Brake cleaner should be used to clean the caliper piston and guide pins completely.
- High-temperature brake oil should lubricate the caliper piston and guide pins.
- Replace the caliper on the rotor and tighten the mounting bolts according to the manufacturer’s instructions.
- Replace the wheel and tire assembly and return the vehicle to the ground.
- Drive the car to confirm that the vibration is gone.
Brake Fluid Leak
If the brake hoses are not examined after any brake replacement or repair, brake fluid might leak. When the brake pedal is depressed, fluid will escape, or air will be allowed in, causing shaking as the pads bounce off the rotor. While changing pads or rotors, expelling any air from the lines is a good idea.
Worn Suspension
A vehicle’s suspension system is in charge of maintaining stability and managing wheel movement. When the suspension system is worn, the automobile will tremble or shake, especially when accelerating, braking, or turning. Worn suspension components, such as shocks, struts, or bushings, can cause wheel misalignment or uneven tire wear, resulting in vibration or shaking.
Here’s a step-by-step way to resolve this problem:
- Before repairing or replacing the suspension system, it is critical to identify the exact problem. A competent technician can diagnose the issue by thoroughly inspecting the suspension system.
- Replace worn components: Once the problem has been identified, worn components such as shocks, struts, or bushings must be replaced. Because removing and installing suspension parts requires specialized tools and knowledge, this is a job best left to a professional mechanic.
