Brakes weren’t working so I figure I check the master cylinder to see what’s going on, checked under hood and couldn’t find it, followed the brake lines and they lead me to this

seals were blown so I was lucky to find a replacement online, after installing, I noticed a leak by the inside of the front tires, checked the lines and they were OK, took off the tire and saw that the wheel cylinders were leaking, come to find out they were shucked an filled with corrosion

I found out after I drove the van to my house [:0] Lucky I didn’t get into an accident.
