Hi All,
I'm not sure if my remote servo is working properly. I've read a few posts on the forum about pumping the pedal with the engine on/off etc, but am not completely sure whether the servo works. How can I test it without removing it from the system?
I've just redone the master cyl and all of the calipers with new seals and hoses etc. I dismantled the servo, but all of the rubbers were fine, so I cleaned it all thoroughly (there were gunky deposits everywhere) and reassembled it.
With the engine off, the pedal is now rock hard (as it should be). But with the engine running there is now significantly more travel on the pedal than before (about 3/4 of its total movement). I've had a little test drive and have found that I need to push the pedal a lot further to achieve braking, but don't have to push it anywhere near as hard as I was previously used to. With the engine stopped, I can expel the air from the servo with 2-3 pumps of the pedal, and it's rock hard again.
Does this mean the servo is working? I was used to a very firm pedal before that only moved about 1/2 of its total travel, but I'm beginning to think that maybe the servo wasn't working before, and is now.
All I know is that the brakes feel very different, and I don't whether that's a good think or a bad thing!!
Cheers all
