Was bleeding brakes after full caliper overhaul, so pedal goes to floor. Noticed that pedal stiffness would increase approx halfway down, then 'clunk' past the resistance before going easily to the floor. Suspected a dodgy master cylinder, which I removed. But have still got same feel to the pedal, so now I suspect the servo, as its the only thing still connected to the pedal (which is a biiiitch to remove!) Should it feel like this when you get full range of movement to the pedal? Brake servos are usually pretty reliable, but I wondered of the actuator rod is bent? I've double checked that the pedal itself isn't catching on anything. Do I need a new servo? Any ideas or suggestions welcomed. thanks!
