This is about a 2016 fiesta st clutch slave issue but my car has a long back story listed below. Know this is not an oem or dealership molested car but it is my own built daily.
Now at 72,000 miles I have recently had a new issue that began to show as a what i thought was a clutch master failure and was only where the car was driven hard the clutch would sink or not return fully… I proceeded to replace the clutch master and rebelas the system. I did buy a new slave but it seemed to hold vacume pressure and showed no leaks. One week later driving hard the clutch began to slip and when pulled over at work the slave was leaking in the clutch housing. I spent the next morning pulling out the trans and decided to order a new woosh high pressure clutch setup, and just for extra I got a new oem slave and the oem master line along with a cool works shifter I was eyeballing….
a week of driving and all seemed great. A decent amount of breakin driving and I hit the touge for some therapy… I have a rear tire rub I’m working on ( inside back bracket to bumper I’m working on) and clutch began to sink again.
I reached out to Ron and again verified the clutch was correctly placed ( clutch says gearbox on it so it clear what side is out) checked the master found a small seeping connection and fixed it, but also found the joint on the slave was leaking and fixed this. Vacune pressure showed perfect over night so I cleaned it all up and got it back together. On week of driving and started a therapy run through little Tujunga cyn and got to the top and again the clutch failed to return.. I was able to pump it up but by the time I got to my work that night the brake fluid was everywhere under the car. Next morning I limped it home… I notice a few patterns. It’s not the clutch itself but could the brake vacune cause this? I literally felt it under my foot pull away in a right turn. Could the heat from the brake fluid cause this… could the traction or ABs system cause this? I usually turn it off but I know it still has function…
I’m considering separating the clutch system from the brakes? Thoughts… I go through new pads every 4 months, tires every 5 or so months…etc so yes it’s driven hard. Have to flush the brake fluid often as it gets burnt.. ( need brake coolers…)

Below is what I have done to the car thus far.
have loved my little fiesta since purchase… with that said my fiesta was totaled at 13488 miles while parked by a drunk driver hitting the left front.
I personally have a lot of mechanical know how so I took it upon myself to rebuild it myself.
i have a friend that is an expert at frame straitening unibody cars so I bough my car back for a wooping $1500 after it was paid off.
No No trust me it was not truely a total, it required one frame horn to be pulled strait and a new “a” arm, sub frame and all the plastic. I did find a good used motor trans but didn’t need it since the motor mounts were the only part there broken…( the extra motor and trans are still sitting waiting for the originals to fail…)
I first had some fun hand porting every hole on the intake turbo exhaust and anything that looked off… , cleaned up the valves as well all myself…still otherwise all stock motor just slight higher compression…Cobb access port tune and yes it passes smog)
I also added a qualif limited slip diff, cp-e full engine and trans mounts, montune Springs 1inch front strut spacers, 3/4 rear spring only spacers. 25 mm front sway and the ajustable rear bar, móntune intake pipe, cp-e all other pipes, Wilwood front 6 pod full bbk and Wilwood rear big dual piston rear 2011 kit with Timkon bearings all around, hardened 4x108 hubs all around with additional holes for 4x100 pattern…on stock rims with 20mm spacers ( I was running 15mm but the Wilwood kit is thinner and the hubs brought it in some..) for tires I use currently a 235/40/17 and just installed the cool works shifter…(I admit I think the stock was very smooth… so I will report if I like this over time if anyone asks…

Sorry I’m a nut) let me know any thoughts why the clutch keeps failing…
