Possible servo fault

[gsxraddict]

Hi all. I'm building a rally car that I just bought. When driving the car home I noticed the pedal is pretty hard. And from what I can remember on my previous 172 the brakes were very sharp and a soft pedal. This one is not the same. Brakes work ok but not much feel in the pedal. Any ideas. Engine is out at the moment. I don't want to put it all back together then find the servo if fu##ed. thanks

Could have been a bad vacuum hose as well but yea, sounds like a servo problem

Check the pipe is easy to blow through and also check the one way valve is working properly. There's a chance that it could be master cylinder or servo related.

Were is the one way valve. I've checked pipe work etc. I've already bought one off here now. Mines visually pretty corroded so
I'll just replace it. Master cylinder is also being replaced with a cup m/c

The one way valve is at the end of the pipe that goes into the servo mate.

Just checked the one way valve. I can't blow through from the engine side but I can from the servo side. I would assume this is working correctly.
