How to Know if You Have a Bad Wheel Cylinder
The wheel cylinder is a critical element of a drum brake system, commonly discovered on the rear wheels of older or some modern vehicles. When you apply the brake pedal, hydraulic pressure is sent to the wheel cylinder, which pushes the brake shoes against the metallic brake drum, slowing down or stopping the vehicle.
Does Your Car Have Drum Brakes?
Drum brakes are typically located at the rear wheels of many cars. However, since disc brakes became standard for front wheels in the 1970s, most cars now have disc brakes at the front. In Malaysia, older cars or those with less advanced brake systems may still use drum brakes at the rear.
To verify if your car has drum brakes and wheel cylinders, check your owner's manual under the "Specifications" section.
What Are the Signs of a Failing Wheel Cylinder?
Once you’ve confirmed your car has drum brakes, look for the following signs of a failing wheel cylinder:
- Soft Brake Pedal: If your brake pedal feels soft or goes down further than normal before working, this may suggest a brake fluid leak, probably through a failing wheel cylinder. Check the brake fluid level and top it up if necessary. If the problem persists, contact MyMechanic for a quick inspection.
- Ineffective Braking: If your vehicle takes longer to stop, pulls to one side when braking, or doesn’t stop evenly, this could be a sign of a malfunctioning wheel cylinder. In such cases, it’s important to seek immediate help from a certified technician at MyMechanic.
- Unpleasant Noises: A sticking wheel cylinder can cause constant contact between the brake shoes and the brake drum, leading to unpleasant noises. This could progress to grinding sounds if neglected, as the friction material wears away. If you notice strange sounds, visit MyMechanic for a thorough inspection.
- Brake Fluid Leak: A leaking wheel cylinder often results in brake fluid pooling around your rear wheels. If you notice fluid on the ground or see it around the wheel, this is a serious sign that immediate repair is needed.
