there is a clip holding it to the top of the slave cylinder and a clip (which you should be able to see ) holding the t-piece to the pipe.Before I go any further I should tell you about a recent experience I had with one of these. Having fitted a new clutch/dmf and cylinders to a mondeo 6 months before the customer complained that she had lost pedal pressure. As I saw a drip of fluid underneath I concluded the slave cylinder must have failed and fitted a new one under warranty. Having put it all back together (6 hours later) I found I was unable to bleed the clutch properly. Having closed the bleed nipple I decided to pump continuously to see if I could get a little bit of pressure. No I couldn't!. When I came and looked in the engine bay I saw that fluid was dribbling down the front of the gearbox. I discovered to my horror and amazement that the bleed nipple was allowing fluid though even when closed! Fords do not sell the t-piece seperately so I had to buy a complete pipe for £63. I natrually only fitted the t-piece. To Make sure this isn't happening to you, top the fluid up to the brim, close the bleed nipple and pump the pedal about 30 times. Check the fluid level. It shouldn't have moved.
Well, today I did some back tracking from the T-piece and undid the gland further back along the pipe and found that the fluid was not even reaching that point. Now it is pointing back to the master cylinder as fluid was getting to it but non coming out on the high pressure side. So it would appear that even though the pedal was up, the piston must be jammed closed resulting in no flow.
Having discovered this I obtained another master cylinder and will be fitting it tomorrow, i will let you know the results.
I have a question regarding fitting this replacement; what is the best sequence of assembly, should I bolt the Master in place first with the white plastic retaining clip that goes into the pedal fitted to the push rod and then fit the pedal after. The last time I did it I tried to fit the whole assembly as one and I had a hell of a job getting the fixing bolts in . As a result I might have damaged it causing me all this grief.
One more thing, what type of bleed screw is it that fits in the T-piece. It is all plastic with a little rubber insert at the end. The one in a 5 speed model is a standard steel one with a pointed end, which I don't think will do the job.
Many thanks for your help,
