Hi all,

I'm trying to find a replacement brake master cylinder, I've checked GSF, Euro nothing shows up at all, ebay there seems to be 50 different variations.

2007 year. 1.9TDI.

My booster part number is 1K2 514 105 AH

Image attached is what I believe is the same, with plug on side.

Can anyone point me in the right direction for brand new part?

Thanks

Hello. Has your break servo failed ? I’m asking as I’m on my third break servo as two have failed on me now in the last year. Seems it’s getting oil into it from the engine somehow and so the vacuum seal is failing. Very dangerous indeed for the break peddle to turn into a brick when you suddenly loose the vacuum assist when breaking at speed ! I was very lucky not to die or kill somebody the first time.

I’m on here now to see if anyone can think of what may be the culprit in the engine that’s letting the oil get into the servo. I’m aware there have an oil matrix instead of a valve on these Tsi engines. But I’ve no idea what I’m visually looking for in the engine.

Will the issue be my master cylinder ?
