940 master cylinder refurb

vickyg · Nov 2nd, 2021, 16:59

Houston we have a problem. I lost braking the other night. No leaks. Bad seals on the master cylinder suspected, no problem can buy a repair kits for a tenner. Have it in bits, the seals supplied bear no resemblance to mine. I was sent the repair kit for pre 1991. I am told for my year and others beyond 91 (1994) the seals are not available - period. PROBLEM!!!

I cannot believe they don't exist. A new MC will be £150 ish for a problem that could be fixed with 10 quids worth of seals. Does anyone know anywhere that might be sitting on old stock? Or maybe I can fit a different MC that won't cost so much. Car off road AGAIN

I've further learned there is no stock as Volvo never made a seal kit for this one

Have a word with Luke (360beast), he may have a master cylinder around.

My concern with used is there's no way of telling it's vintage, mine only passed MOT a few weeks ago with no sign of a problem 😞

Repair kits are a no with me. The problem is usually a worn bore and replacing seals is only very short lived.

There will be some of these second hand about for sure as they don't come up as a problem very often try luke he will hopefully find one for you

With such a safety critical item why would you want to risk anything other than a new part?

When you can get new I fully agree but in same cases new is not even a option
