Helping you stop on a dime every time

Brake Fluid

Brake fluid that delivers as expected without compromise

Your vehicle’s brake lines course with fluid that translates your brake pedal pressure into the squeeze at its calipers or wheel cylinders. The hydraulic pressure can exceed 600 psi under heavy braking application, and there’s no time to question whether your brake fluid can withstand the pressure or begin to boil. Rather than worry about braking performance, be confident that you’ll stop when you need to because you have AMSOIL brake fluid.

AMSOIL DOT 3 and DOT4 goes well beyond the DOT standards to provide next-level dependability from your braking system. It wards off brake fade and a spongy pedal by locking away moisture to prevent flash-boiling on hard applications and repelling corrosion from within. It’s compatible with all common brake fluid DOT 3 and DOT 4 systems, as well as the newest DOT 5.1 standard.

AMSOIL does not compromise on its chemistry formula for anyone, and what you get as a consumer product is the same product for commercial and industrial use. Unfortunately, that limits where AMSOIL brake fluids can be sold and delivered, and it’s not yet available in Canada, California, and other specific US regions. Rather than sell an inferior product, AMSOIL holds the line to sell you only the best quality, because that’s what we do.

How often should a brake fluid change be performed?

If you’re wondering why the brake fluid needs to be changed, it comes down to two things: wear and tear, and moisture.

First, it’s important to know that the fluid is hygroscopic. What that means is that one of its properties is to absorb water molecules. Moisture can be created inside the brake lines from huge temperature swings from hot to cold and back, and that moisture could corrode the brake system from the inside out. The fluid captures those particles so they can’t affect your brake parts negatively.

Secondly, the fluid can darken and carry particles as metal and rubber parts experience microscopic wear. Over time, the brake fluid goes from a bright, clear liquid to a honey-brown and then coffee-coloured fluid. It’s a clear sign that it’s time for a brake flush.

What happens if you don’t change the fluid? Left alone, your brake pedal will feel spongy and you might not stop as fast as you expect with hard braking. Unchecked for a long time, parts can seize from the inside including calipers, wheel cylinders, the proportioning valve, and the master cylinder.

A fluid flush is cost effective and a great way to maintain your vehicle. For most vehicles, it’s recommended to flush the brake fluid every two years or 40,000 km.
