Bleeding brakes is a very important part of maintaining your vehicle. However most people dread it.
Leaks, low fluid levels, or improper maintenance introduces air into to your brake system.
If air gets into the brake lines, it can prevent brake fluid from flowing properly, causing the brake pedal to feel spongy or soft.
This spongy or soft brake pedal can make it feel like you have a lack of braking power.
If air gets into your brake lines, either from an improper bleed or from a leak, then the force from the pedals compresses the air bubble and not the fluid. That means the energy from your foot isn't getting to the brakes like it should be.
Air expands when the temperature increases. If your brakes are hot, then the air expands and created a higher pressure in the line. This unintentional pressure can cause brake drag and therefore a decrease in gas mileage and premature brake pad wear.
Bleeding brakes removes air and returns your brake system to optimal performance.
Light yellow brake fluid darkens with water absorption
Why you should replace your brake fluid?
Time increases brake fluid moisture, lowering the boiling point. Therefore this increases the probability of brake failure due to vaporization of the fluid . Vapor leads to catastrophic failure
After a few years of moisture absorption, the boiling point is lowered to a hazardous level. Automotive professionals recommend changing your brake fluid every couple of years.
Are you in the danger zone?
Brake fluid with too much water also promotes corrosion and pitting. Such problems lead to very costly repairs down the road.
