RR caliper….
I need to check whether the rust is just at the surface and not damaged the calliper function.....





While the piston wall showed just rust stain, the parking brake mechanism side was covered in full of rusty debris….
The brown bit is not brake fluid but the rust.....




And once again, not only the bleeder screw but also the oil (banjo) bolt were heavily corroded.






The sleeve piston was also covered in surface rust....









RL side was better but still, not acceptable state.





Challenge continues……
