Alright guys,
I have a 2003 VW jetta GLS 2.0 L.
The issue: my brake fluid is leaking. I did a rebuild on the rear calipers for the boot and the inner seals and saw the pistons were all scratched up (rear calipers).
Also, when I press the brake pedal down just far enough, I begin to hear a hissing noise if I hold my foot down long enough and hard enough.
I am pretty sure the calipers need to be replaced but I was told about checking my vacuum line for any leaks.
Need some big time help here. I am tired of throwing brake fluid into the reservoir every one or two weeks.
Thanks for the suggestions
