Parking brake light stays on with parking brake off, brakes seem spongy

Water damage leading to rusting of the calipers and or the lines?

Texted my guy, did some observation traced the leak to a rusted line, no fluid coming from near cylinder or caliper no other wheels have fluid leaking. Took video too big to upload here's a photo instead.

WOW! One year makes a difference. Looks like drum brakes!

Yes I noticed that too, why go from discs to drums that are more expensive and harder to replace?

So rather than start a new thread Im hoping this one is still alive and kicking.The leak persists, the mechanic is MIA and I have no other options but to DIY, I think I can repair it with just some flared line and brake unions, but I need to know what the diameter of the line is? I looked up Chevy P30 brake line and it's indicating 3/8, so there is a repair kit on Amazon with stainless steel flared lines and break unions, but the line is 3/16 and is supposed to be inserted into existing line, so how does that work?

Have you checked with a good parts store? I got flexible brake lines for P30 chassis, although was about 7-8 years ago.

Well originally I was going to cut some of the line and take it to AutoZone but if I I can by pre flared line on Amazon it would be better since I have had good results DIY flare. I may have no choice but to do that and determine what line diameter is.
