Re: Re: 1952 Paris built Normale RSJ 834

I bought my new master cylinder from CAS – it did not last long, about 2 pushes of the pedal. the non return valve failed and the pedal locked up just as I was headed for the garage door.

CAS were very apologetic and sent out a replacement and I sent them the failed part. But this is the problem with these remanufactured parts, you never know and it could happen with anything.

My new CAS parts have worked perfectly since.

I have just done my 4CV master cylinder and that was a similar design (and size) and I chose to keep the original return valve but clean it up. Once bitten……. 😕
