Something usually overlooked are the clevis pins and actuating rods when trying to bleed brakes or clutch hydraulics. Over the years we've found numerous cars with ovaled out rods and worn clevis pins, causing so much "slop" in the mechanical parts that actual travel at the "business end" of the systems is reduced significantly. Something to pay attention to. Case in point are the pins in the photo, from two different customers' cars. Excess freeplay was quite evident in both but the owners couldn't find the reason they weren't getting a full pedal.
