are these structural or can you run the brakes without them?
because they sound exactly like what I'm avoiding. the plastic spring retainer is a piece of plastic that sits over the canti boss and has a metal pin that inserts itself into a hole to the side of the canti boss.
On good designs, the metal pin that inserts into the boss and the spring itself should be a single piece.
On bad designs, the metal pin is in the plastic retainer and another, separate piece of metal, the spring, pushes against the plastic retainer. Eventually, on the bad designs, this plastic cracks, leading to poor adjustment and just odd arm return behaviour.
