How often should the brake fluid in the Excelle be changed?

[DeNaomi]

The brake fluid in the Excelle should generally be replaced every two years or 50,000 kilometers, whichever comes first. During driving, due to wear and the automatic adjustment of the brake friction pads, the fluid level may slightly drop, which is normal. However, if the fluid level drops significantly or falls below the MIN mark in a short period, it may indicate a leak in the brake system. Precautions for changing brake fluid: 1. Regularly change brake fluid: Brake fluid that has been used for too long can deteriorate and absorb moisture, lowering its boiling point, which may lead to brake failure and endanger driving safety. Therefore, it must be changed regularly. 2. Do not mix brake fluids: For brake systems with special requirements, a specific brand and type of brake fluid should be used. Different brands and types of brake fluids have different formulations, and mixing them can degrade the performance of the brake fluid. 3. When changing brake fluid, ensure the old fluid is completely cleaned out before adding the new brake fluid. 4. Avoid introducing air when changing brake fluid: Air mixed into the brake fluid during the change can cause discontinuous discharge of the old fluid, affecting braking performance.

I've been driving the Buick Excelle for almost four years now, and I always change the brake fluid every two years or 40,000 kilometers. This is mainly because brake fluid absorbs moisture over time, which lowers its boiling point and affects braking performance. Last time I delayed the change, the brakes felt noticeably softer and I nearly had an accident. When I took it to the 4S shop for inspection, the mechanic said it also depends on driving habits—frequent stop-and-go city driving causes faster wear, so he recommended checking it six months earlier. If the fluid turns black or becomes emulsified, it's time for a change. Don't skimp on safety; developing a habit of recording mileage is the most worry-free approach.

As an automotive technology enthusiast, I've studied the maintenance manual for the Excelle, which recommends replacing the brake fluid every two years or 40,000 kilometers. The reason is simple: brake fluid is hygroscopic. Over time, increased moisture content can corrode brake system components and even cause vapor lock, leading to brake failure in emergencies. For daily driving, extra attention is needed in mountainous or humid areas. It's best to regularly test the water content with a testing pen. A replacement only costs a few dozen to a hundred yuan, which is far better than major repairs after an incident. Proper maintenance can also extend the vehicle's lifespan.

From my experience driving the Buick Excelle, it's best to change the brake fluid every two years. Over time, the fluid can become cloudy and affect performance - safety always comes first. During each maintenance service, have the technician check the fluid reservoir condition - it's simple and hassle-free.

I was confused when I first started driving, but after learning, I understood that the brake fluid in the Excelle should be replaced every two years or 40,000 kilometers. The manual clearly states this, and you can also check if the fluid in the transparent part of the reservoir turns black or bubbles. If you're unsure, it's more reliable to go to a professional shop for a free inspection. Don't wait until the brakes make strange noises to take action—maintaining safe driving is key.
