The brake is dragging and the wheel rim is overheating: signs of a seized brake caliper and how to deal with it safely (Kirkkonummi)

The brakes are dragging if the wheel does not release normally after braking. Symptoms may include a burnt smell, an unusually hot wheel rim, the car pulling to one side, or the car feeling heavier to drive than usual. If you notice these signs whilst driving in Kirkkonummi, pull over to a safe place and allow the brakes to cool down. Do not touch the hot wheel rim. A noticeable drag should be investigated before your next long journey, as the heat puts strain on the brake components and may impair handling.

Brake drag: recognise the signs whilst driving

A dragging brake does not always start with a loud noise. You may first notice that the car pulls slightly to one side when braking or driving on a straight road. A smell of friction coming from near one of the wheels, a warmer-than-usual rim and a heavy-feeling ride are also signs that should be taken seriously. If your fuel consumption increases without any other obvious change, one possible explanation is that a wheel is constantly braking.

Only check the situation calmly once the car has been brought to a safe stop. Do not touch the wheel rim or brake components with your hands if you suspect they may be hot. Smoke, a strong burning smell or a noticeable deterioration in performance are reasons to stop driving immediately and arrange for the car to be taken for inspection. In Traficom’s vehicle inspection assessment criteria, brake drag is a separate fault to be checked, and the inspection also includes an assessment of abnormal heat build-up in the wheel rims. In Traficom’s guidance This audit method is described below.

A hot rim and the smell of burning are signs that should not be ignored.

The brake drags when the brake caliper does not release

In a disc brake, the caliper presses the brake pads against the brake disc. When the brake is released, the components must be able to return to their original positions so that the pads do not remain in contact with the disc. A seized slide pin can prevent the caliper from moving correctly. The caliper piston may also move stiffly, causing the brake pad to remain too close to the disc. In this case, wear may be concentrated on one side and heat will build up whilst riding.

In some cases, internal damage to the brake hose may prevent the pressure from returning to normal, so it is not advisable to determine the cause of the fault based on the symptom alone. We will inspect the brakes as part of repair services and at the same time we assess the condition of the brake pads, discs, calipers, slide pins and brake hoses. When the cause is confirmed before replacing any parts, the repair is targeted at the correct area. The condition of the brake calipers and slide pins also affects the even wear of the brake pads.

Brake drag: drive safely and take your car in for a service

Make a note of the circumstances in which the symptom occurs. For example, tell us whether the car pulls to one side constantly or only when braking, whether the smell comes from the front or the rear, and whether the problem only starts after driving for a while. If the brake or ABS warning light comes on in the instrument panel, this information will help us narrow down the fault. We can investigate any observations relating to the electrical system fault diagnosis alongside a mechanical inspection of the brakes.

We offer maintenance and repair services for cars and vans in Kirkkonummi. It’s worth booking a brake check as soon as the brake discs get hot, the car pulls to one side or there’s a persistent smell from the brakes. We’ll inspect any faults found and agree on the necessary repairs before starting work. This way, you’ll regain a consistent braking feel and the assurance that your car is once again fit for normal driving.
