I changed this piston boot because of the smaller cut that was visible from the side. Probably after someone put a screwdriver through the rubber trying to prize out a brake pad.
To the inside of the calliper the boot was completely worn out. My concern is if the damage is from heat or from rust tearing the boot. The piston hade some rust pores but nothing big and I managed to polish them down/away.
One theory is that water came in from the cut and gathered in the bottom and the piston started to rust. The other is that heat burned the boot and if so probably the other 3 pistons need a check. What do you think?
