Fantasia
If you recall as while ago I replaced the rear brake cylinders on my Fantasia as one of them was seized and would periodically slow the car down. Once replaced the brakes never felt right. I put this down to how old the fluid looked and set about getting a bleed kit and flushing the system out.
This went well yesterday.
As well as giving me a craving for Guinness the old fluid looked more like I'd done an oil change. Anyway due to the car not having a current M.O.T I used a private farm track to test the brakes and...
...they were the same as before if not worse. :roll:
The pedal would feel firm and the brakes start to bind then the pressure would drop the pedal would travel to the floor before any pressure built up again. If I pump the brake the rear wheels would lock up first and the car would pitch in the direction of whatever rear wheel decided to lock. There is no air is the system as far as I can tell so I pop the bonnet to find brake fluid was leaking out of the master cylinder cap. Could the loss of pressure be due to the cap not being sealed? No, but I changed it for the 750 anyway as it was cleaner and there have been no more leaks from there.
With the rear locking first my next guess was the compensator valve located under the spare wheel. I undid the bolt removed the rubber cover to find the grease had solidified and the piston was locked in place. I cleaned it with some WD40 and a toothbrush and pumped the brake again to see if it would free up but it was solid. Could the compensator valve being stuck be caused by or a contributor to the slave cylinder failing? Again no, it's probably just due to the age of the components. Anyway nowhere local sells them unless I wanted to adapt one from another vehicle to make it fit. As far as I'm aware Cinquecento and Seicento ones are different as well so I had to order one from here...

...fit it when it arrives, bleed the rear brakes again and hope for the best.
Pretty stupid bit of design if you ask me (not that anyone had or tends to) I would have put a bleed nipple on the compensator valve as well as I'm sure air could be trapped in there.
That's three to five day delivery, so Monday is most likely. I'll be cycling to work for another week then.
Much as I enjoy/endure cycling to work I've missed my little car.
