Evanda brake fluid dropping
Summary of the thread
A 2006 Chevrolet Evanda owner noticed a dropping brake fluid level and unusual brake pedal feedback. Despite checking for leaks, no obvious issues were found. Suggestions included inspecting brake lines for corrosion and considering worn brake pads as a potential cause. It was explained that worn pads could lead to a drop in fluid level as caliper pistons extend further. The problem was resolved by replacing the brake pads and changing the fluid.

Thanks! Brake inspection hasn't been done for a while. So, worn brake pads actually cause the fluid level to drop? I thought it was a sealed system.

Yep, as the pads wear down, the pistons in the calipers have to travel further to press them against the rotors. This increases the volume within the brake system, and the fluid level in the reservoir drops to compensate. Still, I'd get the lines checked out. If you are not comfortable with that, I suggest you take it to a workshop

Took it to a shop, and you were right. Worn brakes were the main culprit. New pads and a fluid change later, and it's all sorted. Total cost: 480€ Thanks for the pointer!

Hey, I had a similar issue with my Chevy Evanda. Check the brake lines for any corrosion, especially where they connect to the master cylinder. Also, when was the last time you had your brakes inspected? Could be worn pads causing the fluid level to drop as the caliper pistons extend further.
