Can I Still Drive My BMW After the Brake Fluid Maintenance is Due?
2 Answers
You can still drive your BMW for a certain period after the brake fluid maintenance is due, typically within 1,000 kilometers. Below is the relevant information:1. Introduction: Brake fluid is a liquid medium used in hydraulic braking systems to transmit braking pressure, employed in vehicles with hydraulic braking systems. Also known as brake oil or force oil, it is an indispensable part of the braking system, serving as a force transmission medium. Since liquids cannot be compressed, the pressure output from the master cylinder is directly transmitted to the wheel cylinders via the brake fluid.2. Types: Castor Oil-Alcohol Type: Composed of refined castor oil (45%-55%) and low-carbon alcohol (ethanol or butanol, 55%-45%). At -25°C, the castor oil forms a milky white colloidal precipitate, which increases as the temperature drops, potentially clogging the braking system and causing it to become heavy and ineffective. Synthetic Type: Made by blending ethers, alcohols, esters, etc., with additives for lubrication, oxidation resistance, rust prevention, and anti-rubber swelling. Mineral Oil Type: Produced by refining light diesel fractions and adding thickeners and other additives.
I remember when I was driving my BMW, the moment the brake fluid maintenance reminder popped up, I started worrying about safety issues. Once the brake fluid maintenance is due, it's best not to drive anymore. This stuff is like the lifeblood of the braking system—when it expires, it absorbs moisture and deteriorates, causing the boiling point to drop. During braking, bubbles can form, leading to a spongy pedal or longer travel distance, and in emergencies, the car might not stop in time. Once, I was in a hurry and didn't address it promptly. On the highway, I felt something was off with the brakes and nearly rear-ended another car. After taking it to the shop, the mechanic said the brake fluid had too much water content. After replacing it, everything was back to normal. BMW's braking system is quite sophisticated, and neglecting maintenance can increase wear, such as damage to the calipers or master cylinder. So, for your safety and others', I suggest stopping immediately, calling a tow truck to take it to a professional shop for a fluid change, and not taking any chances by risking a drive.
