Brembo monobloc 4-pot caliper brake pad retaining pins. Taper fit steel pins in an aluminium casting that gets soaked by road spray. Very nearly wrote a caliper off last night trying to drift a corroded-in pin out.
In a similar vein: Land Rover’s conteputous use of aluminium and steel in the same structure for a vehicle that was designed to spend its life covered in mud.
Fiat’s rear drum brakes up to about 2004. The official method of adjusting being to replace absolutely everything, then reverse at full speed and jam the handbrake on repeatedly.
The drum assembly that bosch sold fiat to replace the above mechanism. Seemingly designed and built by an out of work Schwartzwald cuckoo clock manufacturer’s incapable apprentice.
