Signs of a Failing Brake Caliper and Why It Needs Immediate Attention

When it comes to reliable stopping power, brake calipers are critical — yet often overlooked. If you've been feeling your car pull to one side, hearing grinding noises, or smelling something burning near your wheels, you might be wondering: is my brake caliper failing?

In this blog, we’ll break down what brake calipers do, how to spot early warning signs, and how Round Rock Auto Center can keep your brakes working safely and smoothly.

What Does a Brake Caliper Do?

Brake calipers are part of your disc brake system. They house the brake pads and use hydraulic pressure to squeeze the pads against the rotor when you press the brake pedal.

When a caliper starts to stick, seize, or leak, it can cause:

• Uneven braking

• Premature pad and rotor wear

• Dangerous handling issues

Top Signs of a Failing Brake Caliper

1. Car Pulls to One Side While Braking

If a caliper is stuck or applying more pressure on one side, the vehicle may pull to the left or right when braking.

2. Uneven Brake Pad Wear

If one caliper isn’t applying or releasing pressure evenly, it can cause one pad to wear faster than the other — or leave grooves in the rotor.

3. High-Pitched Squeal or Grinding Noise

If a caliper isn’t releasing properly, the pad may stay in contact with the rotor, causing constant squealing or even metal-on-metal grinding.

4. Brake Fluid Leaks Near Wheels

Calipers can develop leaks at the piston seal, which reduces braking pressure and can cause a spongy pedal or visible fluid around the wheel.

5. Burning Smell or Excess Heat

A stuck caliper can overheat, creating a burning smell and even smoke near the affected wheel. This can damage the rotor, pads, and nearby components.

What Causes Calipers to Fail?

Brake calipers are built to last, but wear and tear, exposure to moisture, and lack of maintenance can cause:

• Seized pistons

• Corroded slides or pins

• Rubber seal breakdown

• Brake fluid contamination

At Round Rock Auto Center, we’ll inspect, clean, or replace your calipers as needed — and always recommend replacing both sides for even braking performance.

Can a Bad Caliper Be Repaired?

In some cases, calipers can be rebuilt with new seals and hardware. But if there’s internal corrosion or mechanical failure, replacement is the safest and most cost-effective option.

We use top-tier OEM or equivalent calipers and always test the system after installation.
