Is There a Problem If the Brake Pad Return Spring Is Not Installed?
3 Answers
Brake pads generally do not have return springs, so not installing a return spring does not have a significant impact. However, brake pads with spring holes wear more evenly than those without. Below is some information about brake pads: Introduction: Brake pads are composed of a friction material layer, an insulation layer, an adhesive layer, a backplate, and other components. The brake pads work by the brake caliper pushing the backplate to press the friction material against the brake disc for braking, making the quality of the friction material particularly important. Precautions: Emergency braking causes significant damage to brake pads. Therefore, when driving normally, it is important to brake slowly or use intermittent braking (pump braking) to minimize wear on the brake pads.
From my driving experience, not installing the brake pad return spring can cause serious issues. This small component may seem insignificant, but it plays a crucial role in quickly retracting the brake pads to their original position after releasing the brakes. Without it, the brake pads tend to stick to the brake disc, causing continuous friction. Over time, this leads to overheating and warping of the brake disc, accelerated wear, and increased fuel consumption due to additional resistance when the wheels rotate. Once, I overlooked this small part and felt the brakes becoming soft while driving downhill. Upon inspection, I found the disc surface had turned blue from overheating, nearly causing an accident. Safety is no trivial matter—installing the spring takes only a few minutes but can save you the trouble and cost of replacing the entire brake system. During routine maintenance, take an extra moment to ensure the return mechanism functions properly for a safer drive. Never cut corners to avoid regret later.
When servicing your car, the brake pad return spring must never be omitted. Its job is to help the brake pads return to position promptly, preventing brake drag—similar to driving with your foot not fully off the brake pedal. This causes continuous friction between the brake disc and pads, leading to soaring temperatures that not only shorten component lifespan but may also result in brake failure. Especially during long-distance or high-speed driving, overheating risks increase significantly, extending stopping distances and greatly compromising safety. I've seen many people skip installing it to save effort, only to waste money later replacing discs and pads. It's advisable to install the spring every time you replace brake pads and check if its tension is normal. A small investment yields significant returns—proper maintenance ensures smoother driving and reduces the likelihood of future issues.
