I'm aware if this but I was also aware some vehicles shared this fluid in some vehicles I'd owned.

Just was checking my clutchc feels spongey and it's A big power one so don't know why ATM. Really annoying me.

Going to do whole new fluid flush when I put my new gearbox in . Just annoying me I have I use it for work still

I'd check if theres a brake fluid leak somewhere if the reservoir has suddenly got low :shock: sounds like air has got into the system as a result if things are feeling spongy. I'd go careful until you sorted it out and bled the system imo, if no leak on the lines maybe master cylinder? clutch isn't slipping is it I don't know if the fluid is shared.

Na no slipping just horrid pedal feel and brakes feel minging too but they are also shot in their pads and will be being fixed this week. I'm going to get pads done and brakes and clutch fluid flushes and see how I go.

If it remains I'll buy a new master cylinder if that fails guess I've goosed my stage 4 already lol

Cheers for the replies , it's the clutch feeling soft I'm really concerned about as it was a new fx400 less then 8k ago and I don't launch it, but it became soft after some spirited driving and my gearbox going , I have a new box at home waiting to go in a just hope I didn't ruin a seal on the master cylinder. Does anyone know how much the fn2 master cylinder and slave is ?

Or any upgrades which would go in for a similar price

Caused by seal failure ?

Will take a look later mate and let you know. Where else should I check ? Pedals and firewall ?

All the hydraulics is in the bay or under the car . The reservoir, booster and all lines etc . You need to work out if moisture was in the system or got in . If moisture can get in fluid can get out so it will be easy to find. Refit the pads and re bleed fresh fluid . I would be tempted to put through some cheap **** too to flush it then some high quality fluid . Then monitor the fluid level for a few days

Seal on the reservoir is perfect
