At Hoover Street Auto Repair in Ann Arbor, MI, we educate our customers about several warning signs indicating contaminated brake fluid that requires immediate attention.
The most obvious sign is brake fluid discoloration. Fresh brake fluid is typically a light amber color, but contaminated fluid appears dark brown, black, or murky, sometimes with floating particles visible in the reservoir.
A spongy or soft brake pedal is another common symptom that Ann Arbor drivers experience when brake fluid contains moisture or air, reducing the hydraulic system's ability to transfer braking force effectively. You may also notice reduced braking performance, such as your brakes feeling less responsive, the pedal sinking lower than normal when engaged, or your vehicle taking longer to stop than usual. At Hoover Street Auto Repair, we use specialized testing equipment to measure brake fluid moisture content and boiling point. Still, visible signs our technicians check for include corrosion around calipers, wheel cylinders, and brake lines.
An illuminated ABS warning light or brake warning light on your dashboard can indicate contaminated fluid affecting your brake system's sensors and hydraulic components.
Unusual brake noises, such as grinding or squealing, may occur when contaminated fluid reduces the lubrication between brake components.
Leaking brake fluid beneath your vehicle near the wheels is a critical warning sign, often due to corrosion from moisture-contaminated fluid. If you notice a burning smell coming from your brakes, this could indicate your brake fluid is dangerously low due to leaks or has overheated, and you should bring your vehicle to Hoover Street Auto Repair in Ann Arbor immediately for inspection.
Regular brake fluid testing during your annual brake inspection can identify contamination before it causes expensive damage or compromises your safety on Michigan roads.
