What Causes the Brake Not to Return to Its Original Position?

The reasons for the brake not returning to its original position are as follows: Reason 1: The brake return spring is broken or has lost its elasticity. Replacing the brake pedal return spring can solve the issue. Reason 2: The brake caliper piston is stuck, causing braking resistance. Reason 3: The rear axle bearing is fixed or installed incorrectly, or the rear wheel bearing is worn out. Reason 4: The brake fluid is too dirty, or the master cylinder internal valve is stuck. It is recommended that the owner promptly visit a repair shop for inspection and maintenance to prevent affecting safe driving. Related information about car brakes is as follows: Introduction 1: As the name suggests, it is a mechanical braking device that can slow down the vehicle, also known as a decelerator. Simply put, the car brake pedal is located below the steering wheel. Pressing the brake pedal causes the brake lever linkage to be pressurized and transmitted to the brake shoes on the brake drum, clamping the brake disc to slow down or stop the vehicle. Introduction 2: The car manual brake is located next to the gear shift, connected to the brake lever. Common examples also include bicycle brakes, which rely on rod-shaped brakes fixed on the frame or disc-shaped caliper brakes to decelerate.

I recently encountered an issue where my car's brakes weren't fully retracting. At first, I thought it might be due to my driving habits, but upon inspection, it turned out that the brake caliper piston was rusted and stuck due to accumulated dust and rainwater, causing poor movement. Sometimes, it could also be a problem with the brake wheel cylinder, like insufficient oil pressure or leaks in the hydraulic system. My car has been running for several years, and neglecting regular maintenance can easily lead to such issues. I remember one time after high-speed driving, the brakes overheated, causing the rubber hoses to expand and deform, making the retraction very slow. Dirty brake fluid or air bubbles can also affect the retraction. The solution is to first check if the brake fluid needs replacement to ensure it's clean. If the piston is severely rusted, use a cleaner or replace the part entirely. I recommend having a professional mechanic inspect it with proper tools during regular maintenance to prevent unexpected issues. Safety should never be overlooked—this problem can extend braking distance and increase accident risks in severe cases, so I always take it to the repair shop immediately to ensure everything is functioning properly.

As someone who frequently deals with car repairs, I've seen many cases of brakes not retracting properly. The most common causes are rusted or obstructed brake caliper pistons, especially in areas with heavy rainfall where water can accumulate and corrode components; worn piston seals in the brake wheel cylinders leading to oil leaks, which reduce hydraulic pressure and slow down brake pedal return; or aged and contaminated brake fluid forming air bubbles that interfere with the pressure transmission system. I always remind my friends not to neglect basic maintenance—regularly changing the fluid and cleaning components can prevent issues. If you notice a sluggish feeling while driving, slow down and pull over immediately to check if the brake hoses are swollen or blocked. For drum brake systems, improper adjustment can also cause poor retraction. In short, while these issues may seem minor, precise solutions often require using a multimeter to test oil pressure or having a technician inspect the entire hydraulic circuit to avoid major accidents caused by small oversights. Remember, driving with fewer sudden stops and avoiding waterlogged areas can extend the lifespan of your brakes.

With decades of driving experience, I've often encountered brake drag issues in my younger years. It's usually caused by common factors like dust entering the caliper, making piston movement less smooth; or aging, swollen brake hoses delaying fluid return. Cold weather causing frozen, blocked lines makes lag problems more likely. I start by checking basics: confirming brake fluid level and quality, replacing if needed; then cleaning dust buildup near wheels. Developing gentle braking habits reduces heat damage. If you notice slow return, don't force it—find a safe spot to inspect. Simple maintenance like lubricating pistons often solves it, being both economical and practical.
