Ok here’s a list of import part failures I’ve had -

I installed 2 NEW Orielly’s rear wheel cylinders on a 1970 Camaro two weeks later had to do an emergency stop, both cylinders failed completely

Got a brake light pressure switch from Speedway Motors and during a test drive the switch failed, fluid leaked out where the switches metal and plastic housings were crimped together

I rebuilt two rear disc calipers with rebuild kits from an online parts store, the caliper bores were perfect as were the pistons but after installation the rear brakes dragged. Either the o-rings were too large and/or swelled from the brake fluid.

Had a starter and alternator both fail within a few months from Orielly’s

Also had two different radiators leak, one was an import the other a Walker, both only lasted a few thousand miles.
