Occational Spongy Brakes

So i have a somewhat disturbing problem. While I am driving around, my brakes function normally without any problems, but sometimes when i brake, they get incredibly spongy and sometimes do not slow me down at all. I can quickly fix the problem by lifting my foot off the brake pedal and quickly pushing it down again. The brake fluid reservoir is full and my brake pads are still at 60%, any ideas what could be wrong? This is becoming a more and more frequent occurrence.

Sounds like you have air in your brake lines. I would change out your brake fluid and then bleed the lines. Very easy to do and can be done for $3 worth of fluid and a turkey baster.

Since your in that position of brake bleeding, why not go BG on it? Its a service that has a conditioner that supposedly improves flow of brake fluid. We have BG services at our dealership and the seller is a douchebag. I asked him for a test cart they offer, he gave me a little pad to wipe samples on and clean off with brake dust cleaner. I threw it right back at him and said, "I wont use this" lol.

If bleeding your brakes don't work check your slide pins and your calipers. They could be sticking

Clear sign of air lock. Just bleed brakes and you should be good.
