Kia Maintenance Questions? Ask a Mechanic for Answers ASAP
Hi my name is Gavin can I help you with this ?
It is a expensive nightmare when this happens as it is sucking air in I would really take a good look at all the O rings as when ever I have had this it is normaly down to that the rubber has gone hard or has a small defect.
The way the hydraulics works are the same as most makes and models the O rings are on the end of each pipe there is no straight answer other than it has a very small leak which we know it is a matter of removing every pipe for close inspection and have a lot of patience and take time inspecting each pipe.
You have covered everything else like slave master cylinder etc every time I have had this issue it has been down to a O ring issue it is a nightmare for you and the garage as it never gives external loss of fluid and the air leak is so small. If you need me feel free to get back to me regards Gavin.
Has it always had the vibrations ?
I take it you feel that through the pedal ?
Has it been there from new and if so why has it never been resolved ?
Did you buy it from new and what is the reg number please.
Morning can we exchange personal numbers to discuss your vehicle ? regards Gavin.
The source of the problem for the first question and the second question is down to the vibration from the clutch.
With the vibration it is creating excessive fluid pressure on all the O rings and seals.
Yes the flywheel run out needs to be looked at then work your way back from that.
