What is the problem with the constant leakage of brake fluid?
2 Answers
There are several reasons for the constant leakage of brake fluid: 1. Brake hose rupture (leakage occurs between the brake pump and the pipeline): When the brake hose ruptures, it will cause oil leakage, which will affect the braking effect of the car, so it must be repaired in time. 2. Damage to the sealing ring (leakage occurs on the sealing ring): Brake fluid is highly corrosive, but over time, it will age, and the sealing effect will also decrease, leading to oil leakage. 3. Loose or damaged oil pipe screw (leakage occurs at the brake oil drain hole): If the oil pipe screw is damaged, oil leakage will occur. At this time, just replace it with a new screw. If it is only loose, just tighten it.
I've been driving for over 20 years, and brake fluid leaks are quite common with various causes. Aging brake lines are the main culprit, especially rubber hoses that are prone to cracking or bulging under high temperatures and vibrations, leading to gradual seepage – you'll often spot oil stains on the ground. Worn seals are also very common, like those in the master cylinder or wheel cylinders; when the material deteriorates, the seal fails and fluid leaks through gaps. Loose fittings are another issue, whether from improperly tightened screws or bumps causing connections to come undone. If the reservoir gets hit and cracks, it'll leak directly. I always monitor fluid levels for drops and regularly inspect the entire brake system. At the first sign of trouble, I get it repaired immediately – never delay, because brake failure risks are too high, directly impacting driving safety. I always stress that professional shop diagnostics are the most reliable.
