I cannot see any leaks from the master cylinder side in the engine bay, but on the passenger side hub I can see, what I thought was a leaky Birfield joint ( was like that for a while now ), some wetness around the whole area. I assume that the slave cylinder seals have kicked the bucket.
So now I need to replace them. Anyone have any advice where I can get seals or is it agents only. What type of brake fluid should I use ( dot 3 or dot 4 etc....)?
