What Can Happen To Brake Pistons

[ccrien]

There's plenty of other threads about sticky calipers, rusty pistons and options of stainless pistons etc, but I thought I would post up a pic of the 2 taken out recently from one of my forester 2pot calipers- this is after cleaning them up! Rebuilt using subaru parts, not enough time to order/ wait for delivery of stainless versions, but I made sure the boot was well fitted this time and plenty of brake grease around the boot/ calipers mating surfaces to stop water ingress this time.. Can't believe they were this bad, and one of them more or less seized.

Have seen a lot worse, saw a classic one split and have fluid coming through the centre
